Connecting digital inputs from other equipment

Details

Some devices provide digital outputs to indicate their state. For example, a proximity meter might output a high TTL signal whenever something is close to it.

The ANY-maze Digital interface TTL input ports can be used to connect to TTL (or CMOS) signals of this type. The signal should be connected to pin 1 and ground to pin 2 (odd numbered ports) or pins 3 and 4 (even numbered ports).

After connecting the signal, you will need to configure the ANY-maze Digital interface so that it knows that the port you've connected to is being used to read a TTL input signal - specifically you should set the port to be a TTL input (note that the signal is an output at the device and an input at the ANY-maze interface). You should then test that the input is working correctly using the I/O page, where you'd want to select the relevant ANY-maze Digital interface's Input switch ports.

To actually use the input in an experiment, you'll need to add it to the protocol as an on/off input.
