Author Topic: Software for parallel port relay control?  (Read 30630 times)

I am remotely controlling a station using LogMeIn.  The station has a SPST toggle switch that controls a relay on the tower that switches between 2 antennas.  Trying to figure out an easy way to control that relay remotely.  I came across this simple parallel port relay controller:
http://www.dakeng.com/relay.htm
This would seem to do the trick, except the FKEYBIT software that controls the circuit uses the F8 key to turn the relay on and off.  With LogMeIn, I can click but do not know of a way to trigger the F8 key.

Does anyone have a suggestion how to control my antenna switching relay remotely?  Perhaps different software with an on/off click GUI?  Or is there a way to trigger F8 with LogMeIn?

Think I found the answer to my own question. It can be controlled with my logging/rig control program, Ham Radio Deluxe, Tools > Parallel  Port > Monitor, then click to toggle on or off.

I use LogMeIn to control our club shack computer. The "F" keys DO work...

There is also a free program called DXSoft Switcher that controls all 8 bits of a parallel port from a simple GUI.  Works well.

I use the parallel port monitor on HRD to control the auto bandswitching of my homebrew 600 solid state linear.  I have found it to be extremely reliable and easy to configure. I also use Wavenode to monitor the SWR/PWR in and out of my amp. Wavenode has the ability to control 4 digital outputs, with on-screen buttons.  They provide a very simple circuit diagram to hook up relays to their 5 V digital outputs.  I am going to use that to remotely turn off the line voltage in to my amplifier power supply and in the future to remotely switch antennas, and/or ground them. I also use a DTMF decoder as a fail-safe to shut everything down in the event of an Internet failure in the middle of my operation.  I use a DTMF code to reset my LDC autotuner, if, or should I say when, it wants to lock up and stop fuctioning.

Lots of different ways to accomplish the same thing.

Good luck,

Don

Bill,'

Did you solve your remote relay problem?

If not, I can share with you what we do at K4VV.  We can control about anything remotely and we do.  What's more, we're really cheapskates!  HI

Let me know if I can help.
