connecting i/o devices for any-maze software

This family of second generation ANY-maze Interface (AMi-2) devices replace the original ANY-maze interface (AMi); providing improved performance in a smaller form-factor and at a lower price. Driver set-up, device updates, configuration, testing, etc. are all performed from within the ANY-maze software. All the AMi-2 devices are fully integrated into ANY-maze and connect to the PC via USB, in most cases you don't even need a power cord.The following AMi-2 devices are available for use with ANY-maze:

The Optogenetics interface is designed to independently control up to four optogenetic lasers during behavioural tests performed with ANY-maze. Using the interface, you can either pulse a laser with very high precision at a specific frequency and duty cycle for a set duration, or you can 'play' a series of arbitrary pulses. If your laser supports it, the interface can dynamically adjust the laser's intensity too.

  • Using the Optogenetic interface and ANY-maze, you could, for example, easily set up tests in which a laser would pulse at 10Hz with a duty cycle of 33% for 2 seconds, whenever an animal enters a specific part of your apparatus. What's more you could alter these parameters as the test progresses; perhaps increasing the duration or changing the duty cycle, each time the animal presses a lever.

The Touch switch interface is designed to detect when an animal touches something conductive.

For example, the touch switch can be used to detect when the animal licks at a bottle spout, when the animal's paw touches a metal plate on the wall of a cage, or when the animal slips from a grid and its paw touching a metal floor. In all cases the animal needs to be in contact with something else that's conductive - usually the floor of the cage - so that the animal completes a circuit between the two things when it makes a touch.

The ANY-maze Remote control is designed to provide a simple and practical way to remotely start tests. It consists of two parts: a receiver, which connects to a USB port on your computer, and the remote control itself, which has two buttons and works through walls and at distances of 10 to 50 metres.

The Relay interface has 6 output ports which can be used to turn things on and off under software control. For example, an output could switch on a shocker, turn on a light or activate a pellet dispenser.

  • The AMi-2 Relay interface uses what are called solid state relays (hence the interface's name), but you can think of them as simple on/off switches, like a light switch. In other words, using the Relay interface, ANY-maze can simply open or close a switch, which can be very useful in a wide range of situations:

* Many shockers have 'remote control' inputs, which turn on the shock when the two terminals of the input are connected together. Connect the terminals to a Relay interface output port, and ANY-maze can control the shocker.
* Many pellet dispensers are activated by connecting a specific input to power (or in some cases to ground). Connect this input to one side of a Relay interface output, and power (or ground) to the other, and ANY-maze can dispense pellets.
* In fact anything which can be activated using a simple switch can be controlled by an AMi-2 Relay interface, for example, a cue light, a speaker that plays white noise, a motor that opens and closes a door, etc.

The Digital interface is designed to connect ANY-maze to a wide range of equipment typically found in behavioural labs, such as: levers, photobeams, running wheels, some shockers and pellet dispensers, cue lights, etc.

The Analogue interface is designed to connect ANY-maze to devices which output analogue signals, for example a respiratory gas analyser, a blood pressure monitor or an EEG. The interface can also output digital signals, which can, for example, represent the location of the animal in the apparatus.

The Audio interface has six outputs which can be connected to 4-ohm or 8-ohm speakers. Each output can independently play white noise, tones or a sound file under full software control.
