If connecting via Direct Serial or Modem, then select the COM port that you wish to use on your
PC. This COM port should be configured in Windows for the highest baud rate that your PC will
support, but in any case, should be set to at least 57,600 bps.

If connecting via Direct Serial, no other information is required.
6.
If connecting via Modem, in the “Phone #” box, enter the telephone number of the modem that is
connected to the Omnia at the remote site. Any characters present in the “Phone #” box signal the
Omnia Remote program to attempt a connection via modem!

Click on OK to save all the changes and close the Edit Connection dialog.
If you need to use a Modem Initialization string, you may enter it into the “Modem Init” string box. If you
require a modem initialization string and feel more comfortable building the entire connect string within the
“Phone #” box you may do this. See “Using Custom Modem Initialization Strings” for more information.
If your connection attempt times out before the Omnia can answer, you can increase the value (in seconds) of
the “Connection Timeout” setting. This value sets the amount of time the software will wait for the carrier tone
from the Omnia’s modem before timing out and hanging up the computer’s modem.
Omnia Remote Control supports a wide variety of Hayes command set compatible modems. If you have
difficulty using your modem, you may call Omnia Customer Support for assistance, but please gather as much
information about your modem as possible before doing so.
On the Omnia Side...
Remote Control Using the Optional Omnia PCMCIA Modem
Before use, ensure that the Omnia-approved PCMCIA modem card is fully inserted into the lower PC Card slot
on the back of the Omnia. Press on the modem card's “XJACK” connector to extend the modular telephone
jack. Using a standard RJ-11cable, connect your telephone line to the Omnia modem. Make a note of the
telephone number corresponding to this line, as you will need it later when you configure the Omnia Remote.
Note: The modem card can only be safely installed and removed when the Omnia's power is off. Only the
PCMCIA modem card supplied by Telos Omnia has been tested and approved by Telos Omnia. We cannot
ensure correct operation of any other modem card with the Omnia-3, nor can we provide support for such non-
approved cards.
Remote Control Using a External Hayes Compatible Modem
The Omnia supports nearly every Hayes command set compatible modem available. Please note that in order to
support the widest possible variety of externally connected serial devices the Omnia-3's RS-232 port does not
support hardware or software handshaking. This is of no concern, and we are aware of no instances where this
has prevented an externally connected modem from operating properly. The externally connected modem will
need to auto-detect one of the Omnia's three rear panel serial port's baud rates (9,600, 19200, and 57,600).
Because the Omnia and the modem are both DCE devices, you will need to use a crossover (null modem) cable
between them.
Remote Control Using a Direct RS-232 Connection for Local Communications
When a computer can be located near the Omnia-3, it may be convenient to use a direct serial cable connection
rather than dial up. Use a standard, straight-through serial cable -- null-modem cables will not work! A typical
serial cable will need a DB-25 male connector for the Omnia-3 end, and probably a DB-9 female connector on
the computer end. You should verify the exact type required by your computer.
