I have just purchased a SainSmart 8 USB relay board and have it working wonderfully with SSDR 1.10.16.  However, I would like a little help with the hard wiring part to my Ameritron RCS-4 control box.  Does anybody have some simple instructions to help me connect my relay board to the RCS-4 controller? 
Thanks and 73,
Terry, W0ZS

This is simple to connect, how ever if your asking if it will work using the FLEX USB control panel your on your own.

Simply the RCS-4 has a 4 position switch, a 12VAC transformer so you will need 3 of the relay contacts with the AC transformer tied commonly to the three relays.
It requires 12 Volt AC to one relay, another relay requires +12V DC, and the 3rd Relay requires -12DC, and the 4th position is ALL voltage off so the easiest way is to connect into the RCS-4 control box then the output of each SainSmart8 relay will connect inside the RCS-4 control box to the appropriate points. 

Hope this helps, I run mine from a Control by WEB 4 Relay controller. 
OH VERY important make sure you only have ONE relay on at a time, this is why I use the "Control by WEB" box as it uses Scripts and I built a script so only one relay can be on at a time.
AND don't have your Control Box switched to anything but the OFF position when using it remotely.

Thanks Chris, I have looked at both of the links you have provided me.  Bret, you are close to what I need.  However, I am looking for a simple schematic of where I connect outgoing wires of the relays on the usb board to the  rcs4 controller.

Whoops.  Here is the schematic for the Control box.
