Signal configuration table

Correct signal configuration is critical for all connections. For dial connections, the modem bank (Mbank) uses signal configuration (sigconfig) records to ensure a proper speed match-up between a connection and a modem. Sigconfig records are located in the sigconfig table and are configured in the sigconfig Row Edit dialog box.

Omnicomm computes expected remote response "windows" that are largely based on the remote’s line speed. For this reason, correct signal configuration is critical for non-dial (leased-line) connections and even for normal fixed-speed connections. For example, if signal configuration is specified at 9600bps and the remote actually communicated at 1200bps, then data return would take eight times longer than what Omnicomm expects. Therefore, Omnicomm will stop "listening" after only one-eighth of the data has been returned and consider the message to be "short" and possibly compute a CRC error.

The sigconfig table is used to define communication characteristics for the connection, remote, and modem tables.
