SureCross Quick Start Guide for MultiHop Ethernet Data Radio
Troubleshooting
No Ethernet Communication
Ethernet Port: The green light on the right side of the Ethernet port indicates a proper electrical
connection. If the LED is not green, try a new cable or switch. The yellow light on left blinks when an
Ethernet packet is received properly.
No Radio Communications
LED 1: A quick green flash every 4 seconds indicates the radio is OK or working properly. A red flash every 4 seconds indicates a lost
radio connection; this radio is not communicating with another radio.
To solve this communication problem:
1. Verify only one radio is configured to operate as a master radio and one radio is configured as
a slave radio.
2. Run the binding procedure again.
3. Verify the 1 Watt 900 MHz radios are at least 6 feet apart.
4. Perform a site survey.
LED 2: A amber flashing LED indicates data packets are being sent. If this is flashing very quickly and
the network does not work, or works intermittently, the network is likely overloaded.
Stop all Ethernet traffic and test the connection using the Ping command. If the Ping works reliably, the
wireless connection is good and you must reduce your network traffic level.
For More Complex Systems:
• Always use a managed switch or isolate the wireless Ethernet network.
• Eliminate unnecessary traffic.
• Turn IGMP Snooping OFF.
