I have a couple of Orion-Tr 12/12-9 isolated DC-DC converters on my boat that I would like to control remotely using electronics. To do this, it would be nice to know a bit more about how the remote control works. There are basically two wires that need to be connected on the device. This could of course be done with relays, but I prefer using transistors since they use less power and are more reliable. From the manual, it is clear that I need to manipulate the right hand wire.
The question is: To turn the device on, do I need to pull the voltage up or down on the wire? (probably up) If I need to pull it up, is 5 V enough or does it need to be pulled up to 12 V?
Unfortunately, I am not near my boat right now, so cannot do any experiments on this.
