Remote Control Using Ethernet
The Omnia-3 can be controlled via Ethernet using the optional Omnia-3 Ethernet hardware interface (Part
number 2091-00013). This part supports connection via 10-base-T or 100-base-T Ethernet. Installation and
configuration of this hardware is covered in separate instructions included with the hardware interface. Once
configuration is complete, connections behave identically to any other method.
Connecting via Direct Serial Connection
In the Edit Connection window, create a New Connection and name it. Then fill in the Password box (the
default password is “tomtom”-lower case only!). The password may be changed at any time using the File
Menu “Change Password” option. Note that you must be connected to the Omnia in order to change the
password, and that the password change becomes valid the next time you attempt to log in with Omnia Remote
control. Changing the password here also affects the front panel password used to unlock or login to the unit.
Select the COM port that your computer will use under the drop down list box labeled “Port”. If the Omnia and
computer are connected by a straight through serial cable, you should be able to connect and control the Omnia-
3 locally using the remote control program.
The Omnia is designated as a DCE serial device, and has a DB-25 female RS-232 port connector. Your
computer will typically be a DTE device, and will usually have either a DB-9 or DB-25 male connector. Since
only connections between the same type of equipment require a null modem cable (DCE to DCE, or DTE to
DTE), the Omnia to PC cable should be a straight-through type! A null modem cable will not work!
Connecting via Modem
Configure a new connection, also entering the telephone number to which the Omnia-3’s optional Modem Card
is connected. Then fill in the Password box (the default password is “tomtom”-lower case only!). The password
may be changed at any time using the File Menu “Change Password” option. Note that you must be connected
to the Omnia in order to change the password, and that the password change becomes valid the next time you
attempt to log in with Omnia Remote control. Changing the password here also affects the front panel
password used to unlock or login to the unit.
If your computer needs to dial an access code (such as “9”) to get an outside line, that digit must be entered as
well. Sometimes if the outgoing connection passes through a PBX, it might require a short pause between the
outside line access code and the telephone number you're dialing. In this case, the telephone number will need
to have a comma inserted into it after the '9'. (In the standard Hayes command set, a comma is a “pause”
character). You may use as many commas (pauses) in the dialing string as necessary to get whatever delay you
require for your situation.
Example: suppose you need to connect to a remotely located Omnia and it is connected to telephone number
555-1234 in Area code 717. To make things more interesting, your local PBX system requires you to dial a “9”
to get an outside line. In this case, you'll need to dial “9” to get an outside line, as well as a “1” because it is a
long distance call. In this situation, the correct entry for the “Phone #” box would be:
9,17175551234
To enhance 'human readability', you could parse the telephone number entry with hyphens. Doing this has no
effect on the ability of the program to dial out. The entry in the Phone # box entry would then be:
9,1-717-555-1234
