Introduction
The Catalyst defaults are designed for ordinary telephone line connections. When using the Cellularm there are certain delays that are inherent to cellular connections. The incoming and outgoing sessions will take longer to make connection to selected destination types. These delays will need to be extended.
There are also ways to optimize the performance of data and fax transmissions over a cellular phone network. This is accomplished by the use of modem initialization commands.
Setting Session Delays
The Catalyst has three delays that will need to be changed in order to make incoming and outgoing Cellularm connections:
In order to change the length of these timers, you must either connect with Alarmware™, or make the changes from the front panel using keycodes.
To make the necessary changes using Alarmware™, connect to the unit and go to the "Configuration Menu." From the Configuration Menu, select "Devices." The following dialog will appear:
To change the "Protocol Detection Timer" you will need to select "Session Params" from the Configuration Menu:
Using Keycodes from the Front Panel
Optimizing Data and Fax Transmission
You should also configure the Catalyst modem to optimize performance. To insert a modem initialization command into the Catalyst, select "Devices" from the Configuration Menu and click on the RTU Modem tab:
We also recommend that you enter the same command for the Alarmware™ modem. To access the Alarmware™ modem settings, you should start Alarmware™ and then Cancel the "Select RTU" dialog box. You will then have access to the "Options Menu." From the Options menu, select "Modem."
When connecting with a Remote Data Terminal you will need to add the modem commands to the Windows modem configuration. First launch the Windows Control Panel. From the Control Panel, select "Modems." Select the proper modem from the list of available modems. Click on "Properties." Next click on the "Connection" tab. Next click on the "Advanced" button. You should be seeing the following dialog:
