RE: IR Tx/Rx

["Ian Lowe" <ian@xxxxxxx>]

Ahhhh. This circuit is *not* powered from the Serial Port (although the
original UIRT was) My version of the circuit is powered by a Y-Splitter
Power Cable on one of the Hard Drives in the server...

Extra useful because it provides +5 for the UIRT and +12 for the IR Bus,
although extra nervous-inducing when testing new modules. probably don't
want to fry my PC PSU!

The circuit I supplied to you is the highest res on the net, lifted from
the
site of the guy who came up with the mod to the original UIRT

Time to hide????

Have got the bits from Ian and the circuit is very simple. The diagram is a
little low res, is there a better one on the net anywhere?

Notes: if you want to power the LEDs any harder you will need a separate
power supply and a transistor. The PIC can only source 25ma max and I don't
know what the serial port can supply.

Do folks want this?

Ok, in that case I will have no other option than to stalk Ian
"Board" Bird
instead then ;-)
