Status LEDs
There are three labeled LEDs above the RJ45
connectors. They are used as follows:
LED1 This LED pulses approximately once per
connectors. They are used as follows:
LED1 This LED pulses approximately once per
second when the unit has successful
configured itself and is operating. It may pulse
more slowly if the unit is extremely busy.
configured itself and is operating. It may pulse
more slowly if the unit is extremely busy.
LED2 This LED indicates transmission activity. If the
device is functioning as a transmitter, it is ON
when the radio transmitter is active. If the
device is functioning as a receiver, it is ON
when data is being transmitted on the RS485
network line.

LED3 This LED indicates an error, usually an
overrun. Overruns occurs when the show is
too complex for the transceiver. Meaning that
the unit is unable to keep up with the data
required to run the show. This LED really
shouldn’t light.

Pin Headers
No connections should be made to the two pin
headers on the circuit board. One of these headers
is used to program the board at the factory. The
other is reserved for possible future versions of the
software to provide a limited number of input/output
ports.

Internals
The Easy Light Linker is based on a 10 MIP CPU
directing a 900 MHz transceiver. There is a SAW
filter between the antenna and the transceiver to
provide for superior transmission purity and rejection
of adjacent frequency signals during reception. The
antenna used is a dipole to concentrate transmit
energy and increase receiver sensitivity.
Every effort has been made to achieve maximum
range given the power levels permitted by US and
Canadian radio device regulations.
