5.11 USB EXTENDER RECEIVER
The USB specification severely limits the distance of an USB peripheral from the computer.
The USB Extender allows that distance to be increased to a maximum distance of about
300 feet. The USB Extender Receiver is located near the Personal Daq/56 on the top end
panel of the Data Acquisition Unit. See Figure 5.6. The receiver is powered by an isolated
+5V power supply.

5.12 DIGITAL INTERFACE MODULE
The digital interface module connects the 5V digital outputs of the Personal Daq/56 to the
24V digital inputs required by the backplane. This module consists of an input terminal
strip, an interface integrated circuit, and an output terminal strip. The module is located
adjacent to the Personal Daq/56 Data Acquisition Module. See Figure 5.7.
