• Voltage outside of 12-24 VDC parameters, too high or too low will cause unit to shut down
• Using PoE injector instead of power supply, unit is passive PoE

Issue: No communication (LAN)

• No power to unit
• Check cable connections
• Check cable pin out (see Cabling: ISS Provided Cable)
• Forgot sensor IP address - Device locator tool via direct connection

Issue: No communication (Wi-Fi)

• No power to unit
• Wi-Fi not enabled (see Settings: Wi-Fi)
• Not within range
• Forgot Wi-Fi password - the default is echo123456; otherwise, define a new password (see Settings: Wi-Fi)
