General Setup
Mainboard Testing
Live battery and internal temperature
readings, power to the switched 12 volt
excitation, SDI-12 line tests, audio, and
LED testing can be evaluated via the
Mainboard Testing screen.
Miscellaneous Testing
The date, time, real time clock (RTC)
alarm, View Status button, USB and SD
operations can be evaluated via the
Miscellaneous Testing screen. The RTC
enables the System 5000
™
to properly
wake up and respond to scheduled
Scan Rates and is vital to proper
operations.
Serial Ports Testing
Proper communications through the
serial ports can be evaluated via the
Serial Port Testing screen. To test a serial
port, first attach a loopback connector,
then press the Test Port button. Without
a proper loopback connector, the
port will fail the tests. The loopback
connector should have pins 1, 4, 6, and
9 connected together, pins 7 and 8
connected together, and pins 2 and 3
connected together.
