SR245 Computer Interface
The SR245 Computer Interface module is a powerful tool
for data acquisition. It provides both an analog and a digital
interface between your computer and your experiment.

RS-232 and GPIB interfaces
Both RS-232 and GPIB interfaces are standard features of
the SR245. Simple commands make programming easy from
a variety of high-level languages—all that’s necessary is
the ability to send and receive ASCII strings. For example,
sending “?5” instructs the module to measure the voltage
on the 5th analog input BNC. Other commands allow you to
record in the module’s 3500 point buffer memory, ramp an
analog output at a specified rate (for gate scanning), or read
the contents of a digital counter.

Analog I/O
The eight analog I/O channels can be designated through
software as all inputs, all outputs, or as a combination of
inputs and outputs. All channels have 13 bits of resolution
over the ±10.24 VDC full-scale range, with 0.05 % accuracy.
Digital I/O
Two front-panel digital I/O bits are provided for use as
counters or triggers and can be set or read by the computer.
Additionally, an 8-bit input and an 8-bit output port are
available (on an internal connector) for your own custom
digital interfaces.
