About INT-20X
The INT-20X unit is a breakout box that allows the user access to the PCI E or M Series multifunction I/O boards from National Instruments with a 68 pole SCSI connector. An USB version with built-in interface (USB-6221) is also available.
An USB version for the Measurement&Computing USB 1608GX-2AO interface is also available!
A standard system includes the INT-20X breakout box module, NI-M series board and software to record and generate analog signals and to store the data on hard disk. 2 analog output channels to generate analog signals and a digital port with 8 digital lines to write digital signals are available as well. Usually this breakout box is used with the software package CellWorks or with the free Strathclyde Electrophysiology Software WinWCP and WinEDR. CellWorks is a modular program especially developed for electrophysiological and pharmacological experiments. It is used to automate experimental protocols under computer control.
All analog in- and outputs and the 8 digital lines are BNC connectors. The INT-20X can be triggered manually using a push button or from an external devices via TTL pulses connected to the trigger in BNC connector.
A TTL signal indicating the “Wait for Trigger” status of Cellworks (WAIT) and a TTL signal for synchronizing external devices with the sample rate of data acquisition (SYNC) are available.
The digital POWER OUTPUT port with 8 lines can be used, e.g. to control magnetic valves of perfusion systems directly.
A breakout box is also available as module for the EPMS-07 system.
