LED Indicators
DC Power
If all the LEDs are off, no DC power is reaching the radio modem or the internal fuse is open.
Successful power-up is indicated by the Pwr/Tx LED showing a continuous GREEN state for
Remotes or an alternating Red/Green for Access Points.
When the transmitter is active the Pwr/Tx LED is in a RED state.
Note: The J Series radio will take approximately 45 seconds to boot up - during this time, the DC
power LED will remain solid green and various LED activity may occur. Please wait at least 45
seconds before attempting to use radio.
Received Signal Indicator
A regular flashing GREEN LED indicates that the modem is synchronised to its Access Point. The
GREEN LED will also flash when the modem is receiving data.
A regular flashing RED LED indicates the REMOTE is not synchronised to a Access Point or
BRIDGE. Check the antenna, all RF connections, and the radio configuration as the Subnet ID may
not match the Access Point or there may be insufficient RX signal or too much interference.
LAN 1 & LAN 2
The Red TxD and Green RxD LEDs indicate ethernet status on the two LAN ports. These LEDs will
show solid Green when an Ethernet Link is established and will flash Orange to indicate Ethernet
data transmission is occurring.
Port A Data Flow
The RxD/TxD LEDs indicate data flow into/out of the user port. Data being sent to the port for
transmission is indicated by a RED flash, and data being received over the air and then sent from
the port is shown as a GREEN flash.
Error LED Indications
In some circumstances the radio will indicate an error state. This is shown as all LEDs flashing
RED for 1 sec and then a pattern of green LEDs for 1 sec. The pattern of green LEDs indicate the
type of error. Please consult the user manual for further information.
