Terminal Does Not Start
Properly This section provides general troubleshooting information to assist you when
trying to isolate anomalies.
Check for Adequate Power
A terminal that does not receive adequate power could result in unpredictable
behavior. Refer to
Chapter 2 for power requirements.
Check Indicators at Startup
When the terminal starts, the fault and comm indicators flash on and off, then
the comm indicator flashes to signal progress during startup. When startup is
complete, the comm indicator remains on, and is controlled by the
communication driver or application. The comm indicator typically flashes when
communication is active.
If the indicators remain off, the power supply or logic module has failed. Check
the power cable:
• If the power is not within range, replace the power supply.
• If the power is within range, replace the logic module or terminal.
The table shows indicator states if the terminal powers on and stops during
startup.
