The wires are easily conected to the termi-
nal by loosening the screw for the associ-
ated position, inserting the wire, and then
tightening the screw.
RELAY
There is a bi-color led located at the front
of the reader. This led is controlled exter-
nally (by a controller) in emulation mode
readers, and internally controlled (or
optionally externally controlled) in serial
mode readers.
With the emulation mode reader, the led
line is pulled to ground to make it red, and
pulled up to 5VDC to make it green. Addi-
tionally, you can oscillate the line to make
color variations of red and green. A 50%
duty cycle, for example, will give you
orange.
Normally, upon power start up, the led will
be red.
Serial readers have commands to turn on
and blink the leds.
POWER
Models are avialable which run off of
5VDC, 12VDC, or 24VDC. power usage
(maximum) is about 50ma.
Serial readers may be optionally ordered
with an internal relay. This relay can be
used to control the opening of doors or
other devices.
The relay is a form c relay, meaning there
is one common line, one normally open
line, and one normally closed line.
When the relay is not engaged, the nor-
mally closed line will always have the
same voltage potential as the common
line, while the normally open line will not
be connected. When the relay is engaged,
the normally closed line will not be con-
nected, and the normally open line will
