OPERATION GUIDE
Data receive 3 (Target station output)
Example: Receives 5-byte user data (05h) ‘ABCDE’
Source station = 01, relay station = 02, when the received signal level is -69 dBm (45h)
Data transmit command 3 with ACK:
@DT 05 ABCDE %A 02,03 C
R
L
F
When RI is OF
*DC = 45 05 ABCDE C
R
L
F (default)
When RI is ON
*DC = 45 05 ABCDE /A 01,02 C
R
L
F *1
*01= Note that the ‘%’ for data transmit commands is ‘/’ for data receives.
ACK response (Source station output)
When data transmit command 3 with ACK is issued from the source station, an ACK response is output from the
source station. Regardless of the mode set with the attach RF received signal level mode setting command ‘@SI’,
RSSI information for the received signal at the target station is attached to the ACK response. The ACK response is
issued after the relay time has elapsed.
Example: The appearance of the source station ACK response when the 10-byte (0AH) data ‘PPPPPPPPPP’ is
transmitted with control transmit command 3 with ACK.
Following the characters ‘DC’, the RSSI information and ‘00’ indicating the ACK response are output.
Source station equipment ID = 01, relay station equipment IDs = 02, 03, target station equipment ID = 04
When the received signal level of the target station is -85 dBm (55h)
