Overview
The Data Aggregator DA-300
signals as well as detector outputs from a traffic cabinet. The DA-300
outputs. Production testing and demonstration of a DA-300
traffic cabinet and thus a bench tool capable of simulating these inputs to and receive the
outputs from a DA-300

The DA-300
IO tester (model DIOT) was created to fulfill this need. It provides user

relay outputs displaying the contact statuses.
The DIOT supports a simple intuitive user interface consisting of 36 labeled toggle switches
(one for each DA input), Two front panel rotating knobs (one for DC adjust and one for AC
adjust) and 8 LEDs (one for each relay output). The adjustable AC and DC voltages are
read by two different meters.
Labeled toggle switches apply or remove either AC or DC voltages from an AC or
DC input respectively.
Other labeled toggle switches simulate discrete detector input states.
The left top panel knob when rotated clockwise increases the DC voltage, while
rotating it counterclockwise, the DC voltage drops.
The right top panel knob when rotated clockwise lowers the AC voltage, while
rotating counterclockwise raises the AC voltage.
The front panel toggle switch labeled PWR, turns the tester on or off, when in the
"off" position all AC and DC voltages are removed from the inputs to a connected

regardless of the status of their toggle switches. As a safety feature, if
the DIOT is still plugged in but turned off, the AC voltage will still be displayed.
