Omega Vehicle Security DAQ-16 - Manual (Page 24)

CH0-,CH0+,...,CH7-,CH7+ : Analog inputs to the analog to digital converter. Amplitude and
polarity depend upon jumper settings. The input resistance of these lines is 1.5K ohms
typical.
AOUT0, AOUT1: Analog outputs from the digital to analog converters. Polarity and
maximum amplitude depend on the jumper settings and voltage references. Output
resistance of the analog outputs is typically 70 ohms.
VREF0, VREF1: External voltage references for the digital to analog converters. Input range
is 0 to 5.5 volts with a no-load input resistance of 7.5K ohms.
EXT CLK, EXT TRG, EXT INT: External clock, trigger, and interrupt inputs respectively.
Inputs are TTL compatible.
DOUT0, DOUT1, DOUT2, DOUT3: TTL compatible digital output lines.
DIN0, DIN1, DIN2, DIN3: TTL compatible input lines.
