Connecting to the Service Port
The service port on the SNC is an RS-232C port, configured at 19200 Baud, with 8 data bits, 1 stop bit, no
parity and either hardware flow control or Xon/Xoff flow control.
To connect the SNC service port, a service terminal will be required. The service terminal can be any
standard personal computer that contains a serial (COM) port. Connection between the SNC and the
service terminal is established using a 9-pin to 9-pin straight through cable.
