I'd like to know how to use the I/O connectors and just few examples of electronic circuits to transfer some I/O signals between the 2 RRC.
e.g. if I switch on a contact on the RRC-control, how to activate e relay on the RRC-Radio, or how to get a relay or led on on the RRC-Control, activated by a status signal on the RRC-Radio. Which supply should I use? I suppose the 8V on the connector are non enough to use relays...
Idas about which other ways could I use these I/O signals (apart from keyers, CW pads, etc.).
could be this one a replacement of the webswitch?
I really appreciate.
thx in advance.

if you refer to this thread (http://www.remoterig.com/forum/index.php?topic=341.0), I'm not able at all to open the gif files. I do not know why. I tried in several ways, could you help me?
thx in advance.
regards.

A while ago the forum's attachments somehow got corrupted. I was unable to restore them. So the only way of fixing it is for the author of them to upload them again. Sorry about that.

thx a lot now it's more clear.
I imagine that the resistance 1K2 means 1K ohm, and if I need just to use a led, I can just connect it in the same way as for the diode within yhe 4n35.
while, if I need a led together with the relay, I'll connect it (clearly with 1K ohm resistance) btw the +12 and the collector of the 4n35.
Am I correct?
regards.

1k2 means 1k2 = 1200 Ohm and not 1000 Ohm
the rest is ok
