Using A Direct Serial Connection; Connecting Via Modem - Omnia 6EX Installation And Operation Manual

Using a Direct RS-232 Connection for Local Communications
When a computer can be located near the Omnia-6EX, 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-6EX end, and probably a DB-9 female connector on the
computer end. You should verify the exact type required by your computer.
Remote Control Using a 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.
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-6EX
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-6EX'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.
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
