INTRODUCTION
This section provides specifications for ICS's Models 4807 and 2307 Data
Acquisition and Control Boards and Models 4867 and 2367 Data Acquisition
and Control Modules. All specifications and functional descriptions apply
equally to both types of units unless otherwise stated.

DESCRIPTION
1.2.1
All Units
All units covered by this manual provide the same analog and digital
interface that contains digital and analog signals to control external devices
and input digital data, analog voltages and temperature readings from
external devices.
The analog section of the interface provides four analog outputs, six analog
inputs and four thermocouple inputs. The analog outputs are programmable
over a 0 to 5 Vdc range. The analog inputs are single-ended inputs with
programmable ranges of
±
10,
±
5, 0 to 5 and 0 to 10 Vdc. The thermocouple
inputs accept type J thermocouples and can read temperatures from -100
°
C
to + 400
°
C.
The parallel digital interface provides 32 programmable digital lines with
TTL levels for controlling devices or for inputting digital data. The digital
interface is user configurable into gated inputs and/or latched outputs in
increments of eight bits. As inputs, each data line has a pullup resistor for
sensing contact closures or for interfacing with CMOS signals. As outputs,
