SECTION 6: WAM USE and TROUBLESHOOTING
Refer to the WAM Installation Guide (IRF or Cellular version) to perform initial WAM installation and testing.
WAM Use
Once installed, the WAM (including its integrated modem) automatically communicates with both VACs and the
PowerFleet Vision Pro system software. Normal operation does not require any further human interaction.
Note:
Wi-Fi deployments do not require WAMs, however they can be used as supplemental communication.
