Hi Velleman support,
I am using a VM110 and put the digital outputs 1 to 8 to the K8023S. I am using a 12 volt battery connected to the 12-15v terminals of the receiver and both LD11 & 12 light up. When I set any or all of the digital outputs on from the VM110, I do not get a corresponding LED on the receiver lighting up. Are there any other connections I need to make?
I have connected all the outputs from the VM110 to the K8023S and the +VTX- to the correct terminals on the K8023 receiver.
As I mentioned I have connected a 12v battery to the 12-15v terminals. The battery is a new one giving 12.9 volts.
Hope you can help,
Peter Luton
[quote]I have connected all the outputs from the VM110 to the K8023S[/quote]Have you connected also the GND terminal to COM terminal of the K8023S?
Does the LEDs on the receiver unit be lit if you connect the input terminals on the K8023S to COM terminal?
Hi Velleman 255,
Connecting the COM and GND worked fine. I now have LEDs lighting up at will. The next step is to connect it to a K6714. Is it possible to install any number of relays to this board or is it only 8 or 16?
Thanks for your help,
Pete

Hi Vel255,
Is there any reason why I should just not install the transformer on the K6714 and fit connectors to the 12-15 volt output points on the PCB so I could use a 12 volt battery instead?
This would solve my problem of not being able to use the device outdoors.
Cheers,

Please make sure the right polarity of the battery to avoid damaging the unit.
Hi Vel255,
I am using the relays on the K6714 to switch 12 volt DC solenoids. What is the best way to protect the relays from the back-EMF of the solenoids? Is it enough to fit a diode in parallel with the solenoid coil with the Cathode on the +ve side of the supply? If so, what would be the best diode to use?
Cheers,
