Antenna Genuis Band Changing Tutorial LAN/BCD/Pin to Port

Thought it might be useful to some to detail my experience with the 8 x 2 Antenna Genius Plus. I've had a cluster of Alfa-Delta switches to select the multiple beam/wire antennas and it was messy and clumsy. Then got a used 8 x 2 8-Pak from Array Solutions which really cleaned up and simplified antenna switching, but when the Antenna Genius (AG) came out with the automated antenna/band switching, I had to get it and never looked back. It was the first and most logical step to station automation with four different methods of selecting antenna ports. The DIP switch must be set to the control mode desired and are detailed in the manual referenced below. There is a 25 pin male connector (just like a VGA monitor connector) for Port A and another for Port B.

1. LAN control - In this mode the AG gets band data from any 6xxx using the TCP/IP network. The AG must be connected to the same sub-net, you configure the AG via PC app and can assign what band and/or frequency ranges you want to be assigned to what 1 of 8 antennas connectors. Works great, but downside is have to have the shack PC on all the time.

2. BCD control - In this mode AG gets band data from any 6xxx using the standard BCD protocol. A USB to parallel adapter would send the BCD to the AG. Big advantage is that no PC is needed, so great if you operate remotely.Unlike the LAN control where you can assign frequency ranges to certain antenna ports, the BCD control method is just band data and does not select any antenna if outside of the standard ham bands.
3. Pin-to-Port control
- In this mode you can use an external switch for manual switching. You
can buy a control box or DYI, just apply appropriate 12 volts to one of 8 pins of the 15pin connector to select one of 8 antenna ports.
4. Interface Genius control - In this mode AG gets band data from Interface Genius, using the TCP/IP network. Interface Genius is a product also by http://www.4o3a.com

I use LAN control and the application software run on the PC is pretty good and useful if your in the shack, it is not perfected yet for remote use. At this time there is no way to control AG from Maestro but it is planned in an upcoming SmartSDR release. I can see myself eventually building a box with 2 rotary switches with LEDs so to manually control things, this will be especially useful when I want to use a different radio with Port A or B on the AG.

How to Interface the AG to a Flex 6xxx for BCD control
You will need a USB to parallel adapter for Port A and Port B for SO2R but for simplification I will detail just connecting just to Port A. The DIP switch must first by set to BCD control for Port A which the AG manual indicates select switch 2 to ON. For Port B switch 4 to ON. Again, I've reference manuals with links below.
This USB to parallel adapter I used was:

but Flex also has one you can buy, http://cart.flexradio.com/USB-to-Parallel-adapter-for-the-FLEX-6000-series_p_1001.html

Luckily I found an old shielded 10' VGA cable which gave me lots of length to get to my radio. Was going to cut the end off the cable but decided just to use 5 pins of this header plugged into the female VGA connector pins 11 - 15.

The USB to parallel adapter has color coded wires with jtab connector on each, this is what I used from adapter to VGA connector:
  • black (ground) on adapter to VGA pin 15 on VGA connector
  • brown (BIT4) on adapter to VGA pin 15 on VGA connector
  • green (BIT3) on adapter to VGA pin 15 on VGA connector
  • yellow (BIT2) on adapter to VGA pin 15 on VGA connector
  • orange (BIT1) on adapter to VGA pin 15 on VGA connector
Plugged the VGA cable into the Port A connector on the AG and the other end, plugged the adapter into a USB hub that I have connected to my 6700, I selected USB Cables in the SmartSDR menu, saw the new cable, made these changes:
  • Name: Antenna Genius
  • Cable Type: BCD
  • Source: TX Slice
  • Type: HF-BCD
  • Polarity: Active High (default)
Tested and worked as should. I used the TX slice as the source because I'm using RXA for receive antenna and I don't want to accidentally select a receive only antenna as a TX antenna.

Ideally, until the AG app can be run remotely on a computer to control the AG antenna switching and/or AG control added to the Maestro I would like the AG software modified to sense control method instead of having to manually select the DIP switch. So if the AG does not see a LAN connection to the App on a PC, then it should default to BCD control, if no BCD is sensed then look for Pin to Port control. Simple enough right.
