7.2. Controlling the OM2501A with Flex Radios Series 6xxx
There are two possible methods to connect the Flex Radio series 6xxx to the OM2501A:
•
Using the SmartSDR CAT program
•
Using the USB connector at Flex 6xxx
Flex Radio 6xxx series connection using SmartSDR CAT
Choose the control port in the SmartSDR CAT window that you will use to control the power amplifier.
It must be an existing serial port – a hardware COM port in your PC or an USB to serial port adapter.
Connect the chosen COM port and the transceiver port ( TCVR DB9 )to the OM Power amplifier with
a null modem serial cable (both ends of the cable have a female DB-9 connector and pins 2 and 3 are
crossed).
You must assign this serial port to the TX slice that is associated with the Flex 6XXX.
otherwise the amplifier will not set on the proper frequency.
