Connecting photobeam arrays

Details  

Photobeams arrays consist of a number of photobeams mounted in parallel. A typical use for an array is to detect rearing; here the array is positioned horizontally above the apparatus floor such that the animal will only break beams in the array when it rears.

The ANY-maze Digital interface photobeam array port can be connected directly to photobeam arrays made specifically for AMi. These arrays are available in a number of sizes, including 40cm x 40cm and 100cm x 100cm. Unfortunately, arrays from other manufacturers won't work with ANY-maze.

To connect the array you just need to plug it in it to a port on the ANY-maze Digital interface (the array is supplied with a connector already wired-up). 

After connecting the array, you will need to configure the ANY-maze Digital interface so that it knows that the port you've connected to is being used for a photobeam array. You should then test that the array is working correctly using the I/O page.

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