604A|604D|604E: Data Acquisition Signal Interface

request a quote

The 604A|604D|604E A/D Signal Interfaces were designed to enable physiology researchers to easily interface any Aurora Scientific dual-mode muscle levers, force transducers, high-speed length controllers and stimulators to a National Instruments PC-based A/D card. All models can be mounted in a rack, the 604A and 604E models are 1U (1.75”) high while the 604D is 2U (3.5”) high. All models have BNC connectors on the front that connect to other Aurora instruments and one or two data connector(s) on the back. All models include BNC patch cables, BNC terminators and a BNC T-fitting.

The front-panel connections are separated into 3 main groups: A/D inputs, D/A outputs and Digital I/O. Analog inputs measure the signals coming from other instruments, D/A outputs provide analog control signals for other instruments and Digital I/O lines allow for triggers in and out and stimulator timing output. The 604A provides eight A/D inputs, 2 D/A outputs and 6 Digital I/O lines. The 604D provides two independent 604A units contained within a single enclosure. As such the inputs and outputs are the same as for the 604A but there are 2 sets of them. The 604E provides eight A/D inputs, 4 D/A outputs and 4 Digital I/O lines.

The Stimulator connection (I/O 3) is used to connect the A/D software to an external stimulator. Depending on the stimulator being used, the output from the Stimulator connector may simply trigger the stimulator to perform a pre-set stimulation routine or Aurora software products can be used to control pulse width, pulse frequency, frequency duration, train, train frequency, and train duration.
