5.4.4 Test commands and Responses
5.4.4.1 @CT Test data transmission
Transmits test data from the source station for the time specified. Specify ‘ON’ to transmit data continuously, specify
a count value when transmitting for a specified time, and specify ‘OF’ to stop transmission. The transmission data is
‘
C
R
L
F
’ sent repeatedly, and the receive response of the target station is ‘*DR = 00’. If there is any input data during
transmission, the data is transmitted.
Default: ‘OF’
Value: ‘ON’: Continuous transmission (on), ‘OF’: Continuous transmission (off), Count value: ASCII code that
expresses 01h to FFh
The count value is 10 seconds per count. The maximum value is FFh, 2,550 seconds.

・If the Destination ID matches, data
receive is output for specified time.
・To measure the RSSI of the test signal,
set the target station Equipment ID to
'FFh' and use the '@RA' command.
5.4.4.2 @CP Packet test
Transmits data for packet testing.
Transmits data packets to the specified target unit, and the target unit returns the data without change. Any packet
length from 1 to 255 bytes can be specified.
Format 1: ‘@’ + ‘CP’ + data size + data + ‘/’ + route infor ‘C

Format 2: ‘@’ + ‘CP’ + data size + data + ‘C

ss: Shows the data size in 2 hexadecimal digits and ASCII characters. Value: 00h to FFh, maximum 255 bytes
DD...D: D expresses 1-byte data. Value: 00h to FFh, amount of data: maximum 255 bytes
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 Format 1, the route information is entered directly in the command.
With Format 2, 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.
