5. Serial Communications Option
If your Genesis-VP™ has a communications connector on the side, you may
connect it to Decatur’s large display signs, in-car video, or a Personal
Computer which is running Decatur Electronics’ software. If connecting to a
Personal Computer, plug the 9-pin end (DB-9 connector) of the computer
cable into the serial communications port on your computer. Use the cable(s)
that come with the sign or software (if purchased). Make sure you select the
correct value under “port” on the secondary menu.
6. Field Tests
There are two field tests to verify the accuracy of the GENESIS-VP™.
6.1 Self test
Pressing the TEST button on the display initiates a system self-test. This test
checks the left and right numeric displays and runs a simulation of the target
speeds. The Genesis-VP™ will not power down while a self-test is in
process.
Display (LCD) test
The segments in the left and right displays will be illuminated in a circular
pattern to test for faulty Liquid Crystal segments.
Circuitry (DSP) test
The Digital Signal Processor will be tested. “PASS” or “FAIL” will appear
on the display when test is completed.
Speed simulation
The Genesis-VP™ verifies vehicle speed acquisition using synthesized
Doppler frequencies corresponding to the series of four speeds listed below.
“PASS” or “FAIL” will appear on the display when test is completed.
The speeds are:
MPH 15, 30, 45, 60 (if your Genesis-VP™ is in MPH)
KPH 25, 50, 75, 100 (if your Genesis-VP™ is in KPH)
