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.
Turn the K3 off, unplug the RS232 cable from the K144XV and replace the K3’s top cover. Be sure to
connect the loudspeaker (see Replacing the Top Cover on page 17).
Turn the K3 on again and confirm that the K144XV transmits and receives normally.
Serial Port Control
The Serial Port is provided primarily for updating the firmware (see Using External Transverters with the
K144XV
The K144XV may be used with higher-frequency converters and the KXV3 interface will provide band data to
control the external transverter. The
CONFIG:XV1 ADR menu selects the band data to be sent. The default for
the K144XV is Int. Trn0. Int. Trn0 through Int. Trn9 provides band information for external transverters. See
Band Data in the K3 Owner’s manual for details about the data signals.
Firmware Updates on page 20). However, certain commands can be useful if troubleshooting is required or for
special applications.
