LCD Timer
Default: OFF
The display can be automatically turned off after a preset time using this feature. Adjust the
timer to a value between OFF and 3,600 seconds.
RS-232
Default: Yaesu CAT
This setting governs a number of peripheral features. It can be set to the following modes:
JUMA TRX2
This mode is used to enable serial communication with the companion JUMA PA100D
100W linear amplifier.
Yaesu CAT
This allows communication with PC logging programs, and emulates a Yaesu transceiver. For
a list of commands that are emulated, please see Annex C.
Kenwood CAT
This allows communication with PC logging programs, and emulates a Kenwood TS-480
transceiver. For a list of commands that are emulated, please see Annex D.
Voice Memory
This mode is used with the accessory voice memory board.
Test
This mode is used to verify the integrity of the transceiver’s internal circuitry and software, as
well as check that the serial communications port is working correctly. In this version of the
firmware several serial port bugs were corrected, and a user help feature added which briefly
describes the operation of each command.
Connect the transceiver to a PC, use a suitable terminal program, ensure that the speed
settings are correct. Send the letter I, ?, H, or h from the PC and the transceiver should
respond with a screen of information. The actual usage of these commands in beyond the
scope of this document, and in any case is only likely to be of interest to those wishing to
customise the software.
Note that these commands are not in any way destructive – they cannot permanently affect the
overall operation of the transceiver. For a brief description please see Annex E.
Baud Rate
Default: 9600
This allows setting the speed of the serial port from 1,200 – 115,200 Baud. The default of
9,600 is usually satisfactory.
