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>
