Any suggestions would be appreciated. I can handle any electronics but very limited on programming.
The Sainsmart relay board works well and is genuine FTDI so it is supported by the USB cable feature of SmartSDR.
Since the RCS-8V doesn't have a BCD input this is your best option. You can program it as a BIT cable and each relay will be closed for a particular band. You can use this in place of the rotary switch control box. Connect the common to +12v (relay board must have 12v as well) and each of the relay control wires to the N.O. contacts. Then set it up in SmartSDR as a BIT cable and assign the bands you want to switch on for each control wire. Dead simple.
I'm using them with DDUTIL and with Denkovi's control software. I didn't realize they could work with the new cables. I have a hamshack pc running Teamviewer and SmartSDR connecting via a VPN (Thank's to Ria's Raspberry Pi Script).
I use the Denkovi boards. Around $23 US. Link is http://denkovi.com/usb-eight-channel-relay-board-for-automation

Following the advice in this thread I ordered a Denkovi 8 position switch which arrived yesterday. A question for Ria, Bill, or whomever: What typed of USB cable do I use to connect the Denkovi to the USB ports on the back of my 6700. Since the Denkovi is an FTDI device does the cable connecting it to the 6700 need to be an FTDI cable or just regular USB? Please pardon my PC ignorance.

I suggest that instead of replacing the rotary control, you consider supplimenting it with whatever relay board you choose & maintain manual control capability. From time to time manual control is desirable for convenience when in the shack or when some electronic thing stops working. I have a reset button on my relay board. If I need to, this button releases all the relays & the rotary control can then make a selection.
Buy a relay board with double throw relays. Wire the rotary switch's common lead through the common & N.C. contacts of each relay in series so that when no relay is selected the rotary switch is active to select an antenna in the normal maner. When any relay is activated the rotary switch will be disabled & the relay will activate the chosen antenna. Each N.O. relay contact wires in parallel with the corresponding "select" lead from the rotary switch.
By the way, this arrangement helps insure that only one antenna can be actived at a time. Some selection systems rely on the rotary switch's non-shorting contact nature which isn't usually a feature of the relay boards, except for possible software safeguards.
1) antenna A is tri-bander (20-15-10 mt)
2) antenna B is vertical 3band (160-80-40 mt).
It means that I have 6 band for just two rele' output.
It should means that for pin 1 (for exemple) I Would set aFrequency range instead of Band ,right? Same must be done for pin 2 (for antenna B) . This is mandatory because more frequency in just ONE antenna, right? OK but frequency range seems does not work...some suggestion? Maybe syntax is wrong for the frequency range or other?
The last chance could be , set frequency (for exemple 20 and 10mt ) rispectly with pin 3 and 4 and put the corrispective rele' contact in parallel with rele cupled with 15mt (left for pin 1). Pleaase some suggestion ...thanks . 73 Roberto IZ2ODM
