Specifying a Default Port

There may be times when you want to specify a default OMEGA port. Specifying a default port enables the host to automatically contact the same OMEGA port with each call. This feature is convenient, for example, if you want to connect to a telephone set at the OMEGA site.

To enable a default port, connect a laptop computer to OMEGA’s DB-9 connector, start a terminal-emulation program such as HyperTerminal, set up the program to use the parameters on page 62, and send the following command from the program: \PD=<port number> <Enter>

In this command, <port number> is a port number from 1 to 8 you want to specify as the default port.

Example: Specifying OMEGA port 4 as the default port: \PD=4 <Enter>

When OMEGA is configured with a default port, the host can dial OMEGA using the dial string for either the Time Delay method or the Second Dial Tone method; however, the port number must be omitted from the string.

Time delay example: ATDT 19495552468,,, <Enter>

Second dial tone example: ATDT19495552468W,, <Enter>

When OMEGA is configured with a default port and receives a dial string with no port number, it waits 10 seconds and then automatically routes the call to the default port specified by the command: \PD=<port number> <Enter>

To disable a default port, use a laptop computer connected to OMEGA’s DB-9 connector to send the following command from a terminal-emulation program: \PD=0 <Enter>
