Hi folks,
I'm trying to interconnect my KX3 and KRC2. I read the posts on this topic
dating
back to early March. The KRC2 is a very versatile unit allowing parallel
operation of
band filters via the BCD outputs and antenna relays the same time. So I would
really
like to get the KRC2 running
When Eric VA7DZ, Fred KE7X and I were all experimenting with KRC2s for
our K3s, I also connected mine to the KX3 with the help of Jack Brindle,
KRC2 expert.
Here's what I did to the KRC2 to make it work in between the KX3 and the
computer:
1. Set KX3 menu item RS232 to 19200b. Set the appr
This is not a good idea - the two are not compatible. The KX3 does not speak
the auxbus protocol the KRC2 needs, plus the voltage levels are not compatible.
The best way to use the KRC2 with the KX3 is to use serial port communications.
Realize the KRC2’s highest data rate is 19200 bps. Also reme
Robert,
The KX3 ACC2 I/O menu parameter should be set to TRN CTRL.
The output of the KX3 ACC2 IO is 3 volt logic while to KRC2 uses 5 volt
logic. It may be that the AUXBUS signal from the KX3 is not properly
switching the input of the KRC2. You may have to add a 3V to 5V
translation circuit
Hello,
I'm trying to interface a KX3/KXPA with a kRC2 band decorder. Basically, I
built a cable to connect the AuxBus pin on the KRC2 XCVR port t the GPIO input
on the KX3-KXPA adapter cable, which is driven by KX3 ACC2 port. This doesn't
seem to be working and I'm not sure the right setting is
