Checking Firmware Revision

1. Turn the K3 off and remove the top cover.

2. Plug the Serial Cable connector into the RS232 connector on the K144XV module (red arrow below). Connect the other end to your computer and run the K144XV Utility program.

3. Turn on your K3 while watching the STATUS LED on the K144XV module. It should flash once, indicating normal operation and that it is ready for firmware.

4. Enter the letter “V” in the Utility program Command Tester. The K144XV will respond with the version of the firmware currently installed. Example: “V1.00;” (revision 1.00).

Installing New Firmware

You must have an active internet connection or have downloaded the new firmware to your computer. Prepare to install new firmware by first performing the steps above under Checking Firmware Revision, then continue as follows:

1. Using the Utility program, start the download. The STATUS LED should flash indicating it is loading new data from the Utility program.

2. When the download is complete, turn the K3 off, wait at least 10 seconds, then turn it on again while watching the STATUS LED. Verify that the STATUS LED flashes once or twice and then turns off, indicating normal operation.

3. Turn the K3 off, unplug the RS232 cable from the K144XV and replace the K3’s top cover. Be sure to reconnect the loudspeaker.

4. Turn the K3 on again and confirm that the K144XV transmits and receives normally.
