I am currently using my parallel port for the same application. I am not sure
how specific your question was, but the output voltage is 5Vdc. However,
remember that this is a logic level which means it will not give not give you
more than ~20mA ( I am not sure). So if your load require more than that, you
might need to use a separate 5Vdc source. The output pins and input pins of
the parallel port that you are looking for is as follow:
INPUT PINS
DB25 BIT #
------ ------
15 3
13 4
12 5
10 6
11 7
OUTPUT PINS
DB25 BIT #
------- ------
2 0
3 1
4 2
5 3
6 4
7 5
8 6
9 7
Good Luck!

| Re: Parallel Port... if you want to see how to get 8 input bits, all straightened out, see: (URL) is also a program called SEEBITS that allows you to easily see all the input bits and set the output bits on and off.

| One manufacturer of such a device is Fascinating Electronics of Oregon. They make a device that hooks to your serial port, you send it "commands" and it answers. The board has a/d inputs digital inputs and outputs a relay output, etc. It works by (...) (25 years ago, 15-Sep-99, to lugnet.robotics.handyboard)
