Parallel Reader Module
In certain cases, it is desirable to attach more than one reader to a single port. The Parallel
Reader Module makes this possible.
Two readers on one port
A customer who does not need to differentiate the direction of travel but wants to control
the entrance and exit through a given door can do so with one port. Installing a Parallel Reader
Module allows two readers to be installed on the same port--one on either side of the door.
Both readers then appear as one to the controller.
The Anti-Passback function cannot be implemented on a particular door if readers on
both sides of that door are wired into the same Parallel Adapter. This is because there is then
no way to assign each reader into a different Passback Area.
Pin required
The Satellite controller can be programmed to require both a card and PIN code for
entry. This can be accomplished with either the Model 225 Card Reader/Keypad Combination
reader or by using a separate card reader and keypad connected together with a Parallel
Reader Module. This option can also be exercised with Wiegand output devices, Magnetic
Stripe, and Barcode readers.
Installation
Figure 15
The Parallel Reader Module is
very easy to install. There are three
sets of connectors, two for the
readers and a third which connects to
the controller port. There are six
terminal pins for each of the three
connectors, all labeled according to
Galaxy Control System’s infrared
reader color code. There are also
three separate jumpers which must
be set correctly for the device to
function. Two of the three jumpers
(JP1 and JP2) are used to select
reader voltage. Each reader can be
powered by either +12 V or +5 V,
depending on the reader
requirements. The third jumper (JP3)
is used to select the reader type. If
these jumpers are not set correctly,
