11.1 Check the Ethernet cable
If you connect a radio and the Ethernet LED does not light on the radio, you may
have used the wrong cable type. In other words, you may have used a cross-
over cable when you should have used a straight-through cable, or vice versa.
Use a straight-through cable when connecting the radio to an Ethernet hub or a
10/100 Base-T Ethernet switch. Straight-through cables are used in most cases.
Use a cross-over cable when connecting the Ethernet radio directly to any device
that is NOT a switch or a hub (e.g., a direct connection to a PC, PLC, or printer).
11.2 LED display
The RLXIB-IHW-66 front panel includes a set of LEDs that indicate the radio’s
status:
LED Description
Power/Status This green LED indicates that the radio has power.
RF Transmit This yellow LED indicates RF transmission.
RF Receive This green LED indicates RF reception.
Ethernet If this green LED is lit, the Ethernet cable is connected. If this LED is flashing, an
Ethernet packet is being transmitted or received.
Signal Strength If only one of these three LEDs is lit, then the radio is linked. If two LEDs are lit,
the radio’s signal strength is fair. If all three LEDs are lit, the signal strength is
good.
If a radio is configured as a master, the middle light of the three Signal Strength
LEDs will always be on, and the bottom Signal Strength LED will always be off.
The top LED on the master will flash if any radios are linked to this master.
After you first plug in the power cable and Ethernet cable to the radio, the
Power/Status LED should be green, meaning that the radio has power. If the
Ethernet LED is green, then the Ethernet connection is working. The RF Transmit
and RF Receive LEDs should blink.
