SERIAL PORT CONNECTIONS
Depending upon the model, the asynchronous serial ports on may be presented as DB 25
sockets, DB 9 sockets or 8-pin RJ45 sockets. On some models, a combination of the above
may be used. The following tables list the pin designations of each type of connector for
each Digi model.
The RS-232 port pin-outs are suitable for both Async and Sync port connections. When used
in Async mode the pins for TxC, RxC & ETC are not required, these are needed for Sync
mode only.
