SteppIR SDA2000 to Flex-6400 USB issue

Member ✭✭
I have two different brand FTDI cables and a the SteppIR S12 cable. For some reason I cannot get the either FTDI cables to communicate between the SteppIR and the 6400. The USB log does show activity though. I am using a SteppIR S12 cable too.
The USB cables are shown in the photo. The SDA2000 is set to data in/out 9600 Kenwood. Autotrak is turned on on the Steppir. The S12 is plugged into the data in (top port) on the 2000.
BTW the S12 cable worked with my desktop hooked into a serial port.
Any thoughts on what I am doing wrong? It seems to be set up correctly per the Flex USB Cables Interface for the FLEX-6000 PDF document.

Zack,
I am running two SteppIR antennas here from the back of the radio. One controller is a SDA 100 and the other is a SDA 2000. Using a FTDI cable I wire it myself like the attached diagram. Note: you must jumper pins 7 and 9.
Controllers are set up for Kenwood 19.2 kbs though the baud rate doesn't matter.
Make sure you are using the Data OUT RS232 connector on the back of the controller.
Your USB settings look OK. I use TX ANT 1 and ANT 2 for tracking the antennas.
Let me know if you need more help.

You also need a null modem adapter on the KPA-500.

I can see that on your KPA500, the radio is sending commends to the KPA500, but the KPA500 is not responding.
This is why you need a null modem cable on the KPA500.

I took the DB9 covers off and found which one had the jumper on 7 & 9. Then I put that side in the data in on the 2000 and it talks now. Thanks! Oh and I labeled both ends of the S12 cable so that I can tell where to plug it the next time I rewire my setup.
This is going to be sweet as I can now sit in my living room and use a laptop and have the 2000 track the rig.0 -
I do have a null modem adapter on the FTDI cable to the KPA500. The 500 is set to radio-serial, serial pol-on and RS232 x 9600. Still not talking.0

Oh the frustration. The 2000 is tracking but the SWR is skyhigh at 5.91. All bands are high. Did a calibration on the 2000 but it made no difference. This is just great

Retract your elements then do a calibration twice. That should fix it. Any arrows stored on the controller?1
-
The calibration worked but the antenna no longer tracks. AutoTrk is on BTW. This is so frustrating.0

We will get it working. Screen shot the USB logs and settings1

After I reset the radio i found that the baud on the rig USB was set to 38400. Once I found that I put it back to 9600 and all is good.
This is so nice being out of the ham shack dungeon and in the living room with the wife. Now she is less of a radio widow.0
