5.4.5 Extended command and extended response
5.4.5.1 ‘@DTxx@CHxx/C’ Change the target station channel
Changes the channel used by the specified target station. Start changing the channels of the equipment located
furthest away.

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.
