When using Yaesu TCVR you need to configure the STOP BIT parameter correctly and
confirm selection with SET.
The communication settings menu can be left by pressing the AUTO button. The amplifier
will enter AUTO mode only if all settings are correct and connection has been established
with your transceiver. You can verify that the correct frequency and transceiver type is shown
on the LCD display.
5.2.2. Connection with not supported TCVRs
For communication with TCVRs, that are not supported by OM2500A (for example JST-245
and older types of Kenwood), an external IF-232 converter is to be used. You can also use
devices from several companies that produce compatible CI-V output which deliver frequency
information in ICOM format through the CI-V output. Then the PA will be connected in the
following configuration:
JST-245 <> DB37- JST-245 cable <> MKII ( or other device which has a CI-V output ) <>
PC. OM2500A is connected to the CI-V output of the CI-V device (MicroHam for example).
Example of communication
5.2.3. Communication loss
If TCVR is not connected or communication settings are incorrect the message
“COMMUNICATION LOST” will be displayed. You can still use PA by entering MANUAL
mode (MAN Button) or by correcting the transceiver connection problem.
