Overview
Overview
TAC has several families of distributed intelligent controllers that function within the
TAC I/NET integrated network system. These include the Unitary Controller (UC)
family, the Micro Regulator (MR) family, and Door Processor (DP) family. Additionally,
TAC offers Application Specific Controllers (ASCs) that use hardware and software
designed for specific applications.
The MRs, DP family, and ASCs use the 7790A LAN Interface Unit (LIU) to connect to
the TAC I/NET controller LAN and communicate with TAC I/NET workstations and
other controllers. When software is successfully downloaded from a TAC I/NET host, the
7790A LIU is reconfigured for a family, or a mixture of families, and the model number
of the LIU changes within the system to reflect its new role.
The LIU can be configured as any of the following interface controllers:
✦
7791 Door Processor Interface (DPI) — This interface manages a portion of the
database for up to 32 Door Processor family controllers.
✦
7792 Micro Regulator Interface (MRI) — This interface supports a mixture of up
to 64 Micro Regulators (MRs) and Application Specific Controllers (ASCs).
✦
7793 Micro Control Interface (MCI) — This interface supports a mixture of up to
64 MRs, ASCs, and DP family controllers.
The LIU provides two subLAN channels (channel A and channel B). Each subLAN
channel supports the connection of up to 32 micro control units (MCUs). When the LIU
is configured as a DPI, a single subLAN channel (channel A) may be used. When the LIU
is configured as either an MRI or MCI, both subLAN channels may be used.
The LIU also allows each subLAN channel to be connected in an open-loop or closedloop installation. When the subLAN channel is configured as a closed loop, the LIU
communicates through both primary and alternate paths, ensuring communication in
case of a break in the subLAN channel cable.
The LIU supports the definition of internal points with all of the extension capabilities
typical of the 7716 PCU. The internal points in the LIU are defined only for point
addresses not currently used by MCUs on the subLAN channels. The LIU has 256KB of
battery-backed RAM for processor use.
Note:
This product contains a Nickel-Cadmium (NiCad) rechargeable battery. This battery
should not be crushed or incinerated when disposing of this product.
Door Processor Interface
For the 7790A to support the Door Processor family of controllers, it must be configured
as a 7791 DPI or a 7793 MCI. Similar in organization to the Unitary Controller family,
the Door Processor family uses the 7791 DPI to connect to the TAC I/NET controller
LAN. The DPI handles all communication with TAC I/NET workstations and other
controllers. The Door Processor Units (DPUs) reside on the subLAN controlled by the
DPI. The Door Processor family includes the following controller models: DPU-7900,
TCON109–09/10
1
Overview
DPU-7910A, DPU-7920, DIU-7930, and DIO-7940. Each controller model provides
different reader options and input/output point capabilities.
The DPI communicates with up to 32 DP family controllers through shielded twistedpair cables connected to channel A of the LIU. The segment extends up to 5000 feet (1500
meters). The DP subLAN connections are provided through an RS485 plug-on termination (TB3). Communication speed on the DP subLAN is 9600 bps.
The DPI maintains Automatic Time Schedules (ATS), Access Initiated Control (AIC),
and elevator control information. If two or more DPUs are in the same anti-passback
zone, the DPI allows them to communicate and enables the anti-passback function
between them. The DPI also contains a redundant copy of a portion of the Access
Control database contained in the DPUs.
Note:
The DPI configuration supports only channel A of the subLAN, and a total of 32 DPUs.
Micro Regulator Interface
When configured as a 7792 MRI, the 7790A provides support for MRs and ASCs. The
MRI handles all communication between TAC I/NET workstations and the MRs and
ASCs residing on both channels of the subLAN.
The MR family of controllers include the MR123-210MB (MRA), MR123-430MB
(MRB), MR123–032BM (MRC), MR123-400MB (MRD), MR88 (MRF), MR632
(MRG), MR16C (MRH), and the MR88R (MRK). Each controller model is aimed at a
specific application environment, although it can migrate to other applications that can
be handled through the Micro Regulator’s DDC and Calculated point functions.
The ASC family of controllers includes the MR-VAV-AX, MR-AHU, MR-VAV-X1,
MR-VAV-X2, and MR-HP. ASCs are similar to MRs except that they include pre-engineered control algorithms. These controllers use hardware and software designed for
specific applications, and can operate in a stand-alone configuration or as part of a TAC
I/NET network.
The MRI forms the communication point between the controller LAN and the subLAN
where the MRs and ASCs reside. The MRI communicates with up to 64 MRs and ASCs
through shielded, twisted pair cables. The MRI connects to two subLAN segments, each
containing up to 32 controllers. Each segment extends up to 5000 feet (1500 meters). The
subLAN connections are provided through two plug-on terminations (TB3 and TB4).
Communication speed to the subLAN controllers is 9600 bps.
Micro Control Interface
When configured as a 7793 MCI, the 7790A allows for the connection of the MR, DP, and
ASC family of controllers on both subLAN channels. The MCI is the connection between
the TAC I/NET controller LAN and the controllers on the subLAN. The MCI communicates with, and supervises, up to 64 subLAN controllers through shielded, twisted-pair
cables. The MCI connects to two subLAN segments, each containing up to 32 MCUs.

Communication
The LIU provides up to six ports, as follows:
✦
A standard synchronous RS485 controller LAN port.
✦
Two standard asynchronous RS485 subLAN ports.
✦
Two asynchronous serial ports. These ports provide access to external PCs, external
modems, and the HC7410 hand held console.
✧
The first asynchronous port (P1) provides a modular TTL level interface to a
standard HC7410 hand held console (HHC) and operates at 1200 bps.
✧
The second asynchronous port (P2) provides an RS232 port for direct connection to a PC or external Auto-answer Hayes-compatible modem. The RS232
port’s baud rate is set through the HHC.
When connected directly to a PC, the LIU performs the functions of a TAC
7801 Tap without consuming an additional LAN address or additional hardware.
When connected to a Hayes-compatible modem, the “Integrated Dial” function (i.e., one-way dial from the host PC to the controller LAN) is provided.
✦
An optional plug-on board providing an RS232 serial port that can be used to
connect an external modem or one of several communication multiplexing devices
is available. Refer to “RS232 Serial Expansion Module” on page 5.
Reset
Upon power loss/restoration, the LIU executes an automatic reset memory test of RAM
and EPROM. The test uses an array of RAM test bytes and a Checksum check on the
EPROM. If the check is successful, control and execution are passed to programmed
memory. A manual reset that is started by pressing the reset button executes the same
tests.
Memory
The LIU provides support for several types of memory with variable amounts of each.
The memory is currently organized as follows:
Table 1. LIU Memory
Socket
Amount
Memory type
U1
32KB
EPROM (Stores boot firmware)
U2 and U3
256KB
RAM (Stores download software and database)
The 7790A LIU provides 512 bytes of non-volatile RAM (NOVRAM) storage. This
memory holds all parameters necessary to establish basic communication with the
controllers after a long-term power outage (for example, loss of RAM).
The software design and memory organization support the complete download of all
software, including revised LAN drivers that are invoked after completion of the download. The downloaded software is held in RAM. The software can be downloaded while
the LIU is on-line with TAC I/NET.

TCON109–09/10
When the LIU is emulating a 78061 Tap, it can store the telephone numbers as a standard
78061 Tap would. Memory is sized to ensure accommodation of at least eight telephone
numbers of at least 25 digits each.
The optional RS232 Serial Expansion Module provides an additional serial interface for
the 7790A. It supports two-way dial or dedicated-line communication as currently
supplied by TAC’s 78061 or 78035 Tap, respectively. The data rate is user-selectable. This
optional interface can be connected to any of the following devices:
✦
Note:
External auto-dial/auto-answer (AD/AA) modem — When connected to a Hayescompatible AD/AA modem, the 7790A will provide the functionality of the 78061
Tap. The following types of modems are supported:
✧
Synchronous — Use a synchronous modem when the controller is loaded with
a TAC I/NET version 4.x or earlier binary file. The controller must also have
TAC I/NET version 4.x boot firmware (EPROM).
✧
Asynchronous — Use an asynchronous modem when the controller is loaded
with a TAC I/NET 2000 or later binary file. The controller must also have TAC
I/NET 2000 or later boot firmware (EPROM).
Ensure that all AD/AA Taps within your TAC I/NET system are configured to use the same
communication protocol — either synchronous, or asynchronous. Mixing AD/AA protocols
will cause communication errors.
TAC I/NET 2000 is compatible with TAC I/NET version 4.x Tap and controller binary
loads. Therefore, when synchronous AD/AA communication is required on a TAC I/NET
2000 system (for example, when using a 78040, 78050, or 78060 Tap), you must continue
to use TAC I/NET version 4.x Tap and controller binary loads.
✦
External synchronous dedicated line modem — When connected to an external
Hayes-compatible dedicated line modem, the 7790A provides the functionality of a
TAC 78035 Tap. Refer to TCON101, TAC I/NET Tap and Repeater Installation
Guide, for a complete description the 78035 Tap function.
✦
Another RS232 data communication device.
Power Supply
Electrical power for the LIU enters at the bottom left edge of the board (TB1). A single,
24 VAC, 50/60 Hz, 40 VA external transformer provides the input power for the LIU.
TCON109–09/10
5
Universal Enclosure
TAC’s universal enclosure provides a protected environment in locations in which dirt,
dust, or other contaminants may exist. The model recommended for the LIU and MR
controllers is the ENCL1813, which is UL916 listed.
The universal enclosure allows both door and back panel mounting, providing additional space for optional equipment such as transformers and electrical junction boxes.
The enclosure includes a key lock for the enclosure door.
The LIU board comes already mounted on a baseplate. That baseplate/PCB assembly is
then mounted into the universal enclosure.
If the perforated backplane is used to mount the baseplates, then the size of the baseplates and the enclosure are the limiting factors. Baseplates vary in length depending
upon the type of controller, but the width is consistent. The baseplate has a keyhole
mounting pattern (see Figure 1 on page 3). All controllers or interface units are attached
to a baseplate for mounting in a universal enclosure. See Table 8 on page 28 for the
dimensions of the universal enclosure.

Caution:
Before you apply power to the LIU, ensure that the 24 VAC leads are connected only to TB1.
Connection to any other terminal block will damage the LIU.
1.
Note:
Connect the 24 VAC input leads from a separate, isolated, 24 VAC, 40 VA transformer to terminals 1 and 2 of terminal block TB1.
Do not attempt to use the same AC transformer for any subLAN device (MR, DPU, UC,
ASC, or transducer) and its associated LAN interface device (MRI, DPI, MCI, UCI, or
I/SITE LAN). This will result in improper operation of one or both of the devices.
2.
Connect terminal 3 of TB1 to a good earth ground using 14 AWG (2.081 mm2)
wire.
Grounding Requirements
To ensure proper operation of the controller, it is imperative that the unit be correctly
grounded as follows:
14
✦
Terminal 3 of TB1 must be connected to a good earth ground through the best
means possible. This should be accomplished by connecting a 14–18 AWG (2.081–
0.897 mm2) wire from terminal 3 of TB1 to metallic structural components known
to be grounded. The controller depends on this ground path for transient protection.
✦
Do not connect the controller LAN shield drain to the LAN terminal block (TB2).
The controller LAN shield drain must be connected directly to earth ground at one
location only. (This may be at the LIU.)
✦
Shield drain wire continuity must be maintained as the LAN cable passes through
each controller. Shield drain wires from each LAN cable segment must be spliced
together, insulated, and tied back such that wires do not come in contact with
ground or any conductive surface within a controller.
TCON109–09/10
Set Up and Operation
This chapter describes the various components of the LIU and how to setup the
controller for operation. This unit mounts on an indoor wall surface in an area that
meets the specifications outlined (refer to “Specifications” on page 28). You should set
the LIU’s address after first powering up the unit and prior to connecting the controller
LAN. For the LIU, identify and record sub-controllers that connect to the sub-controller
LANs on channel A and B. Write this information on a copy of the Sub-controller Chart
located on page 26 of this Installation Guide.
LIU Setup
Setup for the LIU requires the power line frequency setting to be 50 or 60 Hz, depending
on your power source. Use the following procedures to set the LIU controller address,
Tap emulation mode, and baud rates. These procedures use the HC7410 hand-held
console (HHC) to program the LIU.
Connecting the Hand Held Console
The asynchronous port (P1) provides a modular TTL-level interface to a standard HHC
and operates at 1200 bps.
Insert the HHC cord into the RJ11 jack on the LIU (see Figure 10). The HHC can then
be attached to the inside of the universal enclosure using the Velcro® tabs provided with
the HHC.

Hand Held Console Port
The first asynchronous port (P1) provides a modular TTL level interface to the HHC,
and operates at 1200 bps. An RJ11 modular jack is provided along the lower left side of
the controller for connection of the HHC. The HHC is used to set the LAN address and
baud rate of the LIU before connecting it to the TAC I/NET controller LAN, and to field
check the LIU. Refer to “LIU Setup” on page 15 for procedures using the HHC.
RS232 Port
The second asynchronous port (P2) provides an RS232 port for direct connection to a
TAC I/NET host PC, or external Hayes-compatible modem. The RS232 port’s baud rate
is set using a HHC. Refer to “Setting the LIU Tap Baud Rate” on page 17.
When connected directly to a PC, the LIU performs the functions of a 7801 Tap without
consuming an additional LAN address. When connected to a Hayes-compatible modem,
the “Integrated Dial” function (i.e., one-way dial from the host PC to the controller
LAN) is provided. Refer to “Setting the LIU Tap Emulation” on page 16.
Port P2 provides asynchronous communication through a 9-conductor, D-Subminiature connector. This port allows the direct connection of a host workstation or asynchronous modem to the LIU. The circuit connections at this port are typical of the serial
COM port on the PC. Use cable number CBL072 for DE-9, and CBL073 for DB-25
connections to PC COM ports. Use cable number CBL074 to connect the LIU to an asynchronous modem using a 25-pin connector.
RS485 LAN Ports
The three RS485 LAN ports (TB2, TB3, and TB4) are accessed through 5-position
terminal blocks located along the bottom edge of the LIU (see Figure 12). TB2 provides
a communication pathway to the TAC I/NET controller LAN while TB3 and TB4 provide
support for two sub-controller LAN channels (channels A and B).

Not Used
Protocol – The RS485 LAN port uses a synchronous data link communication (SDLC)
protocol and implements a token passing bus to regulate access to the controller LAN.
The LIU controls the RS485 LAN port through a serial communication controller
located on the processor chip.
LAN Node Address – The controller LAN node address (0–63) of the LIU is selected
using an HHC. Refer to TCON073, HC7410 Hand Held Console User Guide for operating
details of the HHC.
The LIU controller LAN address can occupy a single node address or a range of two
consecutive node addresses. The first address identifies sub-controller LAN channel A
while the second consecutive address (if used) identifies sub-controller LAN channel B.
When entering the controller LAN node address, it must be entered as a range. If only
one channel is used, channel A for instance, enter the same address twice. Refer to
“Setting the Controller LAN Address” on page 15.
Note:
The LIU, configured as a 7791 DPI, supports only 1 station address. Once the LIU is configured as a 7792 MRI or a 7793 MCI, the device can be configured as 2 stations.
Data Rate – The data rate for the RS485 SDLC controller port on the LIU is selectable
from the HC7410, with the current selection maintained in nonvolatile storage. The rate
selection supports 9600 or 19,200 bps. The normal rate is 19,200 bps. Refer to “Setting
the LIU Controller LAN Baud Rate” on page 17.
Sub-controller LAN
When connected through ports TB3 and TB4, the LIU can communicate with the MCUs
on channels A and B of the sub-controller LAN. When configured as a 7791 DPI, only
Channel A (TB3) may be used. When communicating with MCUs in a 7792 MRI configuration or configured as a 7793 MCI, both A and B (TB3 and TB4) channels may be
used. Each sub-controller LAN channel may have up to 32 sub-controllers. Both subcontroller LAN channels have a primary and alternate connection on the terminal block
(see Figure 12). The LIU uses the primary and alternate terminals to connect a closed
loop circuit allowing signal flow to either side of the MCUs.

Protocol – The RS485 sub-controller LAN ports use an asynchronous protocol and
implement a host/remote polling network to access the controllers. The sub-controller
LAN can accommodate up to 32 MCUs per channel.
LAN Node Address – Full addressing of a point includes the LIU, MCU controller, and
bit offset information. The format is SSPPBB, where SS is the LIU, PP is the MCU, and
BB is the point bit offset.

✦
Note:
External auto-dial/auto-answer (AD/AA) modem — When connected to a Hayescompatible AD/AA modem, the 7790A will provide the functionality of the 78061
Tap. This following types of modems are supported:
✧
Synchronous — Use a synchronous modem when the controller is loaded with
a TAC I/NET version 4.x or earlier binary file. The controller must also have
TAC I/NET version 4.x boot firmware (EPROM).
✧
Asynchronous — Use an asynchronous modem when the controller is loaded
with a TAC I/NET 2000 or later binary file. The controller must also have TAC
I/NET 2000 or later boot firmware (EPROM).
Ensure that all AD/AA Taps within your TAC I/NET system are configured to use the same
communication protocol — either synchronous, or asynchronous. Mixing AD/AA protocols
will cause communication errors.
TAC I/NET 2000 is compatible with TAC I/NET version 4.x Tap and controller binary
loads. Therefore, when synchronous AD/AA communication is required on a TAC I/NET
2000 system (for example, when using a 78040, 78050, or 78060 Tap), you must continue
to use TAC I/NET version 4.x Tap and controller binary loads.
Use cable number CBL048 for connecting to either of these modems. Refer to the
TAC I/NET Technical Reference Guide for more AD/AA information.
22
TCON109–09/10
✦
External synchronous dedicated line modem — When connected to an external
Hayes-compatible dedicated line modem, the 7790A provides the functionality of a
TAC 78035 Tap. Use cable number CBL048 for this connection. Refer to TCON101,
TAC I/NET Tap and Repeater Installation Guide, for a complete description the
78035 Tap function.
✦
Another RS232 data communication device.
Refer to TCON101, 7800 Series Tap and Repeater Installation Guide, for details about
TAC Taps.
78061 Tap Emulation and Beeper Operation
Beeper calls are used to notify a user of a specific condition occurring in the TAC I/NET
system. This condition is user-definable using message masking and priorities. The
beeper is only a notification tool. It contains no originating code or phone number. It
issues either a tone or vibrates the beeper. To specify a beeper call, select Beeper in the
Type field of the 7806 Configuration editor. If a beeper service is used, enter the beeper
service phone number. If a human response is expected, enter an @ symbol at the end of
the beeper number. This will allow the 78061 Tap emulation to retry on busy and no
answer conditions.
The @ symbol will cause the modem to listen for a 5-second period of silence after the
first ring is detected. The length of time that the modem will listen for this period of
silence is established by the Timeout field in the editor. If a period of silence is detected,
the call will be considered to be completed.
Note:
Some experimentation with the timeout period that is set in the Tap editor may be
required. This timeout period should be set long enough to cause the modem to “hang on
the line” until the 5-second period of silence can be detected.
Since this beeper function is used internationally to dial out to numbers that must have
a human response, it is necessary to accommodate differences in the manner in which
beeper systems and humans respond. When using an external modem (78061 Tap
emulation) you should initialize your Hayes compatible modem with the X4 command
(factory default), which enables your modem to return the busy response code if it is
expected that a person will answer (or not answer) the telephone. This will provide a
rapid response to a busy error.
Note:
It is imperative that any modem used for beeper interfacing operate as described above.
The 78061 emulation will alter the modem initialization timing sequence to always
initialize at a 2400 bps data rate.
Note:
The 7790A LIU will send a setup string to the modem to place it in the auto-answer mode.
This auto-answer function will be set to answer on the first ring.
78061 Tap Emulation and Pager Operation
Select pager operation in the TAC I/NET software by selecting Beeper from the Type
field. Pager operation is used to notify a user of a specific condition occurring in the TAC
I/NET system. This condition is user-definable using message masking and priorities.
The pager is designed to receive a string of characters that are displayed on the recipients
pager. This string could represent a phone number or a recognizable warning code. You
TCON109–09/10
23
may call a pager using the 78061 Tap emulation. The current version of TAC I/NET adds
several additional phone number characters for use with dial strings. Table 7 shows the
additional characters and their definitions.
Table 7. Pager Character Definition

;

!
Issues a Hook flash, forcing the phone to go on-hook for 0.5 seconds.
W
Wait for a dial tone.
A pager differs from a beeper in that the pager sends a string of characters after a 5second period of silence. Also, beepers never use the semi-colon in their call string, while
digital pagers always require the semi-colon at the end of their call string. It is important
that you be familiar with your pager service and phone system so that you know of any
specific characters that may be required to place a successful call. For example, if you
were to enter a phone number for SWB MobileComm pagers in a 78061 Tap emulation
using an ITT System 3100 PBX, you would use the following format:
T9W8172731511#@123456;
The “T” at the beginning of the character string initiates tone dialing, the 9 obtains an
outside line. The “W” causes the Tap to wait for the modem to receive a dial tone before
dialing the pager service phone number. At the end of the phone number is a # sign that
causes this PBX to perform speed dialing, eliminating any unwanted delays. The @ character causes the 78061 Tap emulation to listen for a 5-second period of silence and then
sends the code that will display on the recipient’s pager. The semi-colon causes the Tap
to signal the modem to immediately go on-hook, ending the call.
If your telephone system has no speed dial function, but has a period of silence exceeding
five seconds before the connection is made, add additional @ characters or commas to
prevent the Tap prematurely sending the pager code.
If the number being dialed is really a pager system (particularly a digital pager system),
the modem should be initialized with an X2 command. This will cause the modem to
ignore at least some of the tones presented by the digital pager system (that may be interpreted as busy) when the call is successful.
Note:
24
Some experimentation may be required to find the proper combination of characters to
make the pager call successful.
