paralell or serial plugin to drive external relays ???
is there such a pluggin for girder ???

It really depends on how you plan to wire the relays to the PC.
The LUA Port IO plugin would let you write anything to the parallel or serial ports.

i havent built the hardware yet (or found any schematics),, but i hope to have girder controlling several things via external relays, door latches, curtains, control motors, etc etc, so i will need a bank of relays that can be addressed and directly controled by girder
hardware recomendations (that i can source parts and build) would be nice if you know any :-)

Check out the link in this thread. I ordered one of these but haven't taken the time to try it out. (Work really interferes with my free time)

i did find that post when i searched the forum (like a good boy) :-) hehehe ....before posting,, was looking or something to build myself though,, i have a surplus of parts and the £££ situation isnt good, so cant really afford to buy new things

I'm a software weenie, not a hardware weenie. I have to buy electrical stuff pre-made or it has a VERY low probability of working.

lol,, im more of a hardware,, well bit a both really,, but better on hardware, the IT background i spose :-)
have found a few schematics on the web, but most work via lpt just using any of the 7 ouputs and a 3704 to invert the signal,, so its a simple on and reset,,
would prefer serial and pic based maybe so theres a little more control
in that case i hope someone else reads this post :-)
thanks anyways Mark

would girder be capable of driving this ?

this time it's my turn to help Mark
i guess that girder can drive your device, you just have to know the deveice protocol,and also to see how many relay u want to control.
if only 8 relays are enought for you, u should use a lighter device plugged to your parrallel port, without any processor that need hardware to be programmed.
you also should opt for a little more complexe device that should return relays states

here the cheapest i found (parrallel port input)
but those devices do not protect your port agains electik shock. :-?
i've also found this device that is protected , but include a microcontroller , and only control 4 relays (serial port) :
if you have comments about all of this, or find something interresting in this way, plz tell us
