4422 Swipe Card Reader module
5-3
use with Wiegand card readers and any other card readers which
have no separate clock or strobe output.
For any card reader which has a separate clock or strobe output, the
jumper must be in the A position. The data is read from D1 and
clocked from the strobe signal applied to DØ.
The default setting is B (Wiegand).
JU1/JU4
If you are using a Mag Stripe reader, set the Mag Stripe clock input
(strobe) active-low or active-high on jumpers JU1 and JU4 - position
A for active-low, position B for active-high. If you are using a Wiegand
reader, JU1/JU4 must be set to position A (active-low). JU1 sets the
clock polarity for the left hand reader, JU4 the right.
The default setting is A (active-low).
LEDs
There is an amber LED for each reader. The LED flashes steadily
when the Controller is polling the half of the module correspnding to
that reader. If the LED is not flashing then the module is not being
polled and the reader will not read cards. This is either because the
module is not configured in the Software, or the Software database
has not been downloaded to the Controller. Whenever a card is being
swiped, the LED corresponsing to that reader flashes with a different
pattern, enabling you to see if the module is receiving data from the
card reader. This is helpful when installing the system or fault
finding.
Connecting
External connections are made to the Controller via cables which can
enter through holes in any part of the case using the knockouts
provided. Cables connecting to modules plugged into the
motherboard should be routed to each side of the chassis where there
are cable guides provided. This ensures modules can be removed
easily without cables snagging.
All connections to the module are made to the strip of green
connectors along the front edge of the module circuit board. There is
a duplicate set of connections on each side, one set per reader. The
connectors can be unplugged from the module so you can gain access
to the screw terminals with a screwdriver. Unplugging the connectors
also enables the module to be removed at a later date, leaving the
wiring intact.
