OPERATION GUIDE
5.4.5.2 ‘@DTxx@CHxx/F’ Changing channels of multiple stations at once
Changes the channels used by multiple specified target stations at once. It is possible to change the channels of the
stations and source station entered in the route information at once. The timing by which the channels of the stations
are changed is the moment when, after the target stations receive the change channel command from the source
station, the ACK responses are received by the various stations. Stations that cannot confirm the ACK signal due to
an error remain in their original channel. In this case, investigate the channel range of the system, and change the
channels with the target station channel changing command, starting with the most distant stations.

cc: Enter the channel number in 2 hexadecimal digits and ASCII characters. Value: 01h to 7Fh
rr,rr,...,rr: Shows the route information in 2 hexadecimal digits and ASCII characters. Value: 00h to FEh,
number of relay stations maximum 10 units
With Formats 1 and 3, the route information is entered directly in the command.
With Formats 2 and 4 transmission is based on route information set in the route register with the RT command
or on the content of the Destination ID. When entering the route information, enter the Equipment ID of the
target unit at the end. If no route information is set (NA set for the RT command), the equipment set as the
Destination ID will be the target station.
Formats 3 and 4: To fix the changed channel in the EEPROM, attach the ‘/W’ option.
Example: Change the channel of the target station equipment number = 8F to 14ch (0E) channel. The relay
stations are 01, 02, and 03.

Control response (Source station output)
When the channels of the equipment in the system are changed, a control response is output as the change
completion result.
