Measurement Computing DBK Part 2 - Manual (Page 170)

Overview
The DBK85 is a low-noise, high-speed, unity-gain multiplexer module that provides 16 channels of
differential voltage input. Up to 16 DBK85 modules can be attached to a single LogBook or Daq device,
providing a possible 256 differential input channels. The module’s unity gain of x1 combines with
DaqBook, DaqBoard, and LogBook gains to accept full scale inputs from
±156 mV to ±10 V. The
DBK85’s channels can be scanned at the maximum 200 kHz rate while maintaining measurement integrity.
Hardware Setup
Configuring the DBK85 Module
Up to sixteen DBK85 modules can be attached to a single LogBook or Daq device. Each module must
have a unique channel address because they connect to the primary data acquisition device via parallel
interface.
CAUTION
Adjustment of the channel address must only be performed when the system
power is OFF. Failure to do so may result in equipment damage.
To assign a channel address to the DBK85 module, first locate the DIP switch on the right side of the rear
panel. Four micro-switches [on the DIP switch] are used to set the module’s channel address in binary.
After ensuring that the system power is OFF, adjust the micro-switches to set the desired address. The 16
possible addresses are illustrated in the following figure.
Each module in the system must have a unique primary device channel address.
