Ameritron RCS -4 sainsmart connection points.

W7NIK

I have the Sain smart  USB  board , the RCS -4  has 12vAC going down the coax, 
This Flex community has so much responsive knowledge , 
I been trying to get this to work , not sure if i need to cut traces on the board  take out the rotary completely .?
This will be remote in my house , 
If anyone has pictures  etc that would be great or send me to a web site , that would greatly appreciated . . 

Then I was thinking of BCD data  controlling the RCS -4 ) 

I have learn alot , still alot to learn .:)

SAINSMART boards are junk , 2 already they corrupted my USB ports,  FTDI chip is fake  i guess .  I did connect  the RCS -4 , blew a fuse . Not sure on this simple circuit .

Make sure you pull the ground wire that goes to the Rotors switch and leave the rotory switch to position 4 If you don’t then you will have a short circuit and **** the fuse

Well the ground is couple places , pwr supply, ground leaving going to control box . Ground to the rotary switch is solder into the circuit board?

As I stated before, The Ground going to the ROTORY switch (ONLY),  Looking at the Schematic at S1A it shows the TOP contact of the Switch going to ground, this is the Ground that needs to be removed.
Then Leave the switch in this position which leaves the lead going to the COAX open for your external REMOTE Relay switch to send +12V_--12V and Ground down the COAX. 
Sorry if I am unable to explain this so it is easier to understand, Maybe this is just to complicated for some.

Yes , I make things more complicated, sorry. I even got the schematic for a 2 pole 6 position switch. This sending voltage to the relay box is confusing, the voltage is not steady it throws bursts to just switch the relay I guess. . I ordered a kmtronics board lan connection. The SainSmart board is in conflict with other USB devices, I take the board Out Every thing works . Position 4 I will trace it out

I had to cut the  ground trace on the circuit board. Basically  the component location  and schematic, are different  
ALL works great now, I leave it in position 4  or shut off the power to the controller.
I have position 4 as  1kw dummy load .  Thank you all for the help . I am full remote  to my closet .
