Parameters:
9600 Baud
8 Data bit
NO Parity
1 Stop bit
RTS means ready to send, normally active (+V);
CTS is waiting for the Clear-to-send signal from the control device (PC), if no CTS is sent, Pin 7
and 8 must be shortened inside the connector.
Software protocol:
Data exchange in true ASCII-Code. After any command a Carriage Return (0x0D) will be sent.
The Request-to-talk list is handled internally by the MCS 50 unit.
Please use a straight, standard RS 232 cable.
