Firmware Updating Process - Detailed

Over time, new versions of CallFinder firmware will be issued. When these newer versions

become available, you will want to secure the firmware files (typically by downloading them from

the MultiTech web site) and install them in the CallFinder.

There are three parts to a full firmware update:

(a) updating DID Channel1/Modem firmware (with file name of the form

gpqg<x><y>.hex; where x is a number and y is a letter),

(b) updating DID Channel2/Modem firmware (same file name as above), and

NOTE: You must have the update files on your computer before beginning this

procedure. The latest version of these files will be available on the MultiTech

web site. Put them in a directory on a computer connected to the network on

which the CallFinder unit is running.

NOTE: Updating the CallFinder unit will take it out of operation for a few minutes (allow

10 minutes for each update if you already have the new firmware in a directory

on the host computer). Do the update at a time that is not critical to your

organization's usage of DID service.

To update firmware, follow the steps shown below.

1. Bring up the FaxFinder/CallFinder Manager software main screen. In the Device column,

identify the CallFinder unit on which the update is to be done. Be sure that the Status of that

CallFinder unit is idle before continuing. (You cannot update the CallFinder while it is

handling a call.) Select that CallFinder unit and right-click on it. In the menu that appears,

select Update .
