J-Series Data Radio – User Manual
(1) Pwr/TX - DC Power & TX LEDs
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.
Tx Indicator (Tx) : 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.
(2) Sync/No RX - Synchronisation and No Received Signal LEDs
A regular flashing GREEN Sync/No RX LED indicates that the modem is synchronised to its Access Point. The Sync/No RX LED will also flash
GREEN when the modem is receiving data.
A regular flashing RED Sync/No RX LED indicates the REMOTE is not synchronised to an Access Point or BRIDGE. Check the antenna, all RF
connections and the radio configuration. Some common causes of this error is that the Subnet ID may not match the Access Point or there may be
insufficient RX signal or too much interference.
(3) & (4) LAN 1 & LAN 2 - LAN Link and Activity LEDs
The Green Link and Amber Activity LEDs indicate Ethernet status on the two LAN ports. These LEDs will show solid Green when an Ethernet Link
is established and will flash Amber to indicate Ethernet data transmission is occurring.
(5) TxD/RxD - Serial TxD/RxD LEDs
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 forwarded to the serial port is shown as a GREEN flash.
Firmware Updating and Factory Default Information LEDs
In some circumstances a firmware update or factory default might be required. A special LED sequence is shown during this phase.

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 table for more information.
