9 Firmware Updating

ThefirmwareintheOSMAC Base can be loaded with firmware updates via the serial port number 1

(lower of the two serial ports). Use the following procedure:

1. You may need to reset the Flash memory and reload the database of pagers after loading the new

firmware into the unit. Therefore, before updating the firmware, it is recommended that the pager

database be downloaded and saved as described in the "Retrieving the Pager Database" section

of this manual.

2. Connect a computer’s serial port to the OSMAC Base, and on the computer, run a terminal

emulation program such as Hyperterminal or ProComm. Set the baud rate to 38.4kbps, 8 data

bits, 1 stop bit, no parity.

3. When powering up the OSMAC Base, hold the “-” button down. You should see a sign-on

message from the OSMAC Base that looks like this:

4. On the computer, press Y for yes if you would like to load new firmware into the unit.

5. ThefilenamefortheOSMAC Base firmware is 307xxxxL.BIN, where xxxx is the revision code

and L is a code for the language of the voice prompts. If you are interested in a language other

than English, contact your distributor for availability.

6. Begin the file transfer of the new firmware from the computer, using either YMODEM or XMODEM.

If one protocol fails to work, try the other. When the update is complete, the unit will reset and

begin operation.

7. Check to see whether the old pager database is compatible with the new firmware version. If the

previously programmed pagers function properly, then the installation is completed and the

following steps do not have to be performed. If the pagers do not function properly, then the

following steps must be performed to restore the pager database:

8. Edit the pager database previously saved and add the following on a line by itself before any of the

pager entries:
