System Architecture – Best Practices
One or two ACW2-XN enclosures?
ONE ACW2-XN enclosure
•
is sufficient for up to 8 readers
•
AND if all doors are within reasonable cabling distance of the enclosure
TWO ACW2-XN enclosures are needed
•
for 9 to 16 readers
•
OR if a second group of doors is a significant distance away from the first group. The two
enclosures are linked with an RS-485 cable, saving on long, multiple-reader cable runs.
(Remember that the total door count still cannot exceed the 16-door limit.)
How many AW2 Modules are needed?
•
One AW2 Module is needed for each door that has both entry and exit readers.
•
One AW2 Module is needed for every TWO doors that only require entry readers
NOTE:
•
Any combination of single-readers and two-reader doors is permissible
•
Readers may be independently allocated to any door
•
Whatever the combination, no more than sixteen doors are supported
Example using three AW2 Wiegand Modules:
Any combination of single-reader or entry+exit-reader doors is possible
