Installation Guide
The PC AD1200 board connects to the real world devices
using a 50 way IDC ribbon cable or a 50 pin D connector cable,
available from your dealer or via the HELP line on Intro page 2.
The 50 way IDC connector is arranged as two parallel
rows of 25 pins on a 0.1 inch pitch, the pin outs are given
above.

Signal Types.
The AD1200 card signals may be grouped as follows.
i)
Analogue Inputs.
AD CH0-CH15.
These are the 16 inputs to the A/D converter when in
Single Ended or Pseudo Differential Mode.
Analogue Ground.
The return line for CH0-15. The analogue inputs in
Single Ended Mode are measured relative to this
signal, AGND.
Amp Low.
The return line for CH0-15. The analogue inputs in
Pseudo Differential Mode are measured relative to
this signal.
AD CH0-CH7, & CH0-CH7 Return.
These are the 8 input with the relevant return to the
A/D converter when in using Differential Mode.
ii)
Analogue Outputs.
DAC0 Output, DAC0 Ground.
The analogue output and return line for D/A
converter
connected to analogue ground, AGND.
DAC1 Output, DAC1 Ground.
The analogue output and return line for D/A
converter
connected to analogue ground, AGND.
iii)
Power Outputs.
+12 Volts, -12 Volts and Power Ground.
Power supply lines and return to drive the users own
interfaces. The +/-12 are fuse protected on the
