RX-Vx700 RS-232C Protocol

2. Start Commands

2.1 Startin

Communication

The Ready command is the first command to be sent to the RX-Vx700 at the start of

communication. TOUT0 - 2 in the Ready Command sets communication timeout.

RX-Vx700 sends a Configuration command (Model ID, software version and setting data)

to the host in reply to the Ready command.

The RX-Vx700 will send a Configuration command within 1 sec. after receiving a Ready command from the host. If not, send a Ready Command

again (max 5 times).

If the RX-Vx700 won't send a Configuration command after the fifth retry, cancel the transaction because there may be a problem.
