I converted the hex number incorrectly. Address 53264 decimal works.

If the computer running windows 7 has a built in parallel port I can successfully run the I/O ttl test at address 888.
However that computer is being replaced with a win 7 computer without a built...

I just attached my test device to the computer that will be used for data collection. The led is lit as soon as the device is plugged into the parallel port.
I run the ttl i/o test and enter 888 as...

I have constructed the circuit. Positive of the led to pin 2, negative of the led to the resistor 250 to 470 ohm range, resistor to pin 19 on the connector.
When I plug in the connector to lpt1, the...

Actually Com 1 is port 1016.
I think you meant Lpt 1 is port 888.

I will test your suggestion in the morning.
Thank You

Confident this will work and we can set the pulse duration to...

The computer has a parallel port. Your suggestion is?

I have a serial cable plugged into the 9 pin serial port of the computer. I have attached an led across pin 5 signal ground and pin 4 DTR. The led is off. Now at a dos command prompt I type echo...

I want to attach an led across 2 pins of a 9 pin serial connector and have that led light when a command is sent to that connector (com1)
If I attach an led across those pins and from a DOS command...

Hi John,
Are we able to obtain the schematic/parts list for this black box, or is this something we can purchase from Empirisoft?
You state that your black box has a composite video input, so that...

Hi,
For the first item in our questionnaire, participants must choose their gender. I'd like for the answer to this question to determine which of two questions they will be presented with later in...

That is similar to what I need, but I need it a little different. I've attached what we actually use in the lab. I've tried to play around with it to see if I could modify it to our purposes, but I...

Our lab uses the Affect grid frequently in our lab, but I'm not sure how to create this in MediaLab. Has anybody used this, or anything that resembles a grid as one of their measures?

Basically...
