1 About this Guide
This guide explains how to control the COS using commands through RS-232C communication and transmit
RS-232C data between TX and RX.
There are two modes
“Setting mode” : For controlling transmitter or receiver from external device
“Transmission mode” : For data communication between transmitter and receiver
The setting procedure is common to both transmitter and receiver.
Use appropriate RS-232C cable for connected devices.

2 Command outline
A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases), and parameters (one-byte numbers*). For some commands, several parameters can be specified or
no parameter is required. Processing is executed by sending a delimiter at the end of the command.
Example: @S*S, 1
“,”( a comma, “2C” in hexadecimal) is indicated between a command and parameter and between two
parameters.
An error command is returned if an undefined command or wrong parameter is included.
Example:@S*S, 10
@ERR, 1
If only delimiter is sent, the command list will be returned.
Example:
--------------- HELP (1/2) ---------------
(Com Port Setting Command)
@SCT / @GCT: Set/Get RS-232C Interface
(OTHERS Command)
@GIV: Get ID & Version
@GIS: Get Input Status

4
Set the Receiver ID. *1
Set “[C18]” (RS-232C communication Receiver ID setting) to “01 to 15”.*2
5
Set the Destination ID and Bidirectional enabled ID.
Set the Destination ID using (@S**) command from the transmitter and control device connected
RS-232C.
Set the Bidirectional enabled ID using (@S*R) command from the transmitter and control device
connected RS-232C.
6
Set the RS-232C communication mode of the transmitter and receiver to “Transmission mode”.*3
Set [F99] (Maintenance/Status display menu) to “on” or “ALL” (Always displayed).

7
Set “[F99]” (Maintenance/Status display menu) to “oFF” (Not displayed) as needed.
*1 If the RS-232C communication settings between control device and transmitter/receiver are set correctly,
the Receiver ID can be set using (@S*I) command.
【See: @S*I / @G*I】
*2 Receiver ID “0” cannot be used. Set all Receiver IDs to values other than “0”.
If the same Receiver ID is set to multiple receivers, data can be sent from the transmitter to all specified
receiver. Data can be received only from the receiver that is closest to the transmitter.
*3 If the RS-232C communication settings between control device and transmitter/receiver are set correctly,
the RS-232C communication mode can be set using (@S*S) command.
