LWI MODULE:
The Red STATUS LED located near the center of the board
blinks when a message is received from the Bridge. The
frequency of the blinking depends on the number of LWI
modules configured on the Bridge. As more modules are
added, the blink rate decreases.
The Green TRANSMIT LED located near the edge of the
board is turned on whenever a radio packet is being
transmitted by the LWI module.
The Red ERROR LED located near the edge of the board is turned on when a radio is received but an
error was detected in the packet.
When the LWI module is first powered on, it will attempt to lock to the Bridge radio. The red ERROR LED is
turned on and remains on until a valid message is detected from the Bridge. The module then turns on the
green TRANSMIT LED and the module begins frequency hopping to synchronize with the Bridge. When a
packet is received, the red STATUS LED blinks. This continues until the LWI receives a packet containing a
matching machine ID. At this point, the LWI module locks and operates in the normal mode, blinking the
red STATUS and green TRANSMIT LEDs. Note, if the red STATUS LED continuously blinks at a high rate
and the green TRANSMIT LED remains off, this indicates the LWI module has not seen its machine ID in
any received packet. This occurs when the LWI module is not configured in the Bridge.
