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
adjustable DC and AC voltages to a DA-300

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.
