Overview
IC-100 security installations often require integration with touch-screen control systems, graphic
annunciator panels and camera controllers. TOA offers two options for meeting this requirement:
1. The DI-100 and DI-110 interface products offer a hardware solution—they provide the call
LED outputs and select switch inputs required for graphic annunciator panels. They also
provide relay outputs for camera switcher integration. Using this off-the-shelf method requires
no knowledge of computer programming or serial communication.
2. Integrators using a microprocessor-based product (usually a PC or PLC) as their integrated
system's control center, often prefer direct control and monitoring of IC-100 control station
activity through the IC-100's integral serial port. Using Remote Control and Monitoring
eliminates the need for installing DI-100s and DI-110s and elevates the programmer's level of
control.
This document targets programmers who need an understanding of how they can remotely
control and monitor the IC-100 by communicating through its RS-232 port. The following
document sections provide the details:

Connecting to the IC-100
The MU-110 CPU card includes a DB25 connector for serial communications. Its wiring follows
the RS-232 standard for Data Terminal Equipment (DTE). If the serial port on your equipment is
also wired as DTE (typical for a terminal or PC), connect to the MU-110 using a straight-through
serial cable plus a null-modem adapter. If the serial port on your equipment follows the RS-232
standard for Data Communicating Equipment (DCE, typical for modems), you will not need the
null-modem adapter.
Jumper J1 on the MU-110 CPU Card sets the IC-100 serial communication baud rate. TOA ships
the MU-110 with jumper J1 in position 4, yielding 1200 bps. You may increase the baud rate to
2400 bps by moving jumper J1 to position 3.
Each data byte communicated through the MU-110 serial port contains 8 data bits, no parity and 1
stop bit. The MU-110 does not support flow control.
IC-100 remote control and monitoring features are only available after you purchase and
install optional MU-110 firmware. Any TOA Electronics, Inc. authorized IC-100 dealer may
purchase the optional firmware as model IC-EPROM v2.xR. Installing IC-EPROM v2.xR firmware
disables the "Speech Path Control" IC-SOFT maintenance screen.

Communicating with the IC-100
Message Tables in this Document
This document describes several types of command messages you can use for controlling and
monitoring IC-100 activity. You will find a separate document section for each command message
type. Each command message section includes a brief explanation, followed by a table detailing
the contents of the fields associated with that message type. The ‘Value’ column of these tables
displays hexadecimal values with an "H" suffix, and ASCII character values within parenthesis.
Your development tool(s) may not display all of the ASCII characters represented in this
document. True Type and Type 1 fonts reserve characters below 20H for control functions such
as indicating tabs and page breaks, rather than for printing or display.
Many commercial terminal emulator programs install their own font for displaying “non-printing”
control characters. Similarly, 32-bit versions of Windows ship with a special font, aptly named
“Terminal”, which displays all of the ASCII characters represented in this document. While
Windows’ HyperTerminal and MS Excel support the Windows Terminal font, few other programs
do, as it is neither a True Type nor a Type 1 font.
Message Packaging
All MU-110 serial port messages are packaged using the following format:
<STX><COMMAND><DATA><CHECKSUM><ETX>
The second (<COMMAND>) byte of each message identifies its purpose as indicated below.

of all bytes after STX and adding 30H to each of
the result's two, least-significant, hexadecimal
digits.

Acknowledgment
The IC-100 transmits a six-byte acknowledgment each time it receives an error-free message
through its serial port.

Using the Remote Dial Command
Using the IC-100 Remote Dial Command, you can remotely perform any action normally taken by
IC-100 sub-station or control station users. The command you send to the IC-100 identifies the
line number of the station for which you want to dial and the digits you want dialed.
Answer or place control station calls by dialing C/# C/# followed by the station number. The two
C/# dial digits reset any existing control station activity before initiating the call.

Monitoring Control Station Activity
Using IC-100 remote monitoring, you can request a copy of all information transmitted to the
control stations in the exchange to which you are connected. Once the IC-100 accepts your
request, it sends you the information control stations use for updating their LCD screens as well
as the information DI-100s use for updating DI-110 LED and Relay outputs. IC-100 integrators
typically intercept and utilize the information DI-100s use for updating DI-110 LEDs and relays.
See Interpreting DI-100 Call LED Data for more information.

Interpreting DI-100 Call LED Data
The IC-100 embeds DI-100 call LED messages within the control station display data stream. The
IC-100 transmits one of these 12 byte messages with each control station call queue change. The
table below details their contents. For a complete listing of all control station display data types,
