8-Port Expansion Module Option

cEach comma represents a 2-second pause.

c<port number> is the port number with which the host wants to communicate.

c<Enter> is the pressing of the Enter key on your computer.

Example: ATDT 19495552468,,,4 <Enter>

In this example, OMEGA dials 1 949 555-2468, waits 6 seconds to allow a connection, and connects the line to port 4.

Second Dial Tone Method (Manual Connection)

With this method, the host computer calls OMEGA and waits for a “second” dial tone from OMEGA. The second dial tone signals the host to enter the DTMF tone that corresponds to an OMEGA port.

To enable this method, 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:

\PR=1 <Enter>.

When OMEGA is configured for the second dial tone method, the host issues the following dial string:

ATDT<phone number>W,,<port number> <Enter>

In this string:

•<phone number> is the OMEGA phone number (and area code, if required).

•W indicates that the host is to wait for the second dial tone.

•Each comma represents a 2-second pause.

•<port number> is the port number with which the host wants to communicate.

•<Enter> is the pressing of the Enter key on your computer.

Example: ATDT 19495552468W,,6 <Enter>

To switch from the second dial tone method to the time delay method, use a laptop computer connected to OMEGA’s DB-9 connector to send the following command from a terminal- emulation program: \PR=0 <Enter>
