The ProxNet access control system
consists of a ProxNet Controller and up to 254 ProxNet Readers all connected
on an industry standard RS-485 twisted pair cable.
The intelligent ProxNet Readers have internal nonvolatile memory that stores
tag holder information and transaction records. Each ProxNet Reader makes
its own access decisions and results in a highly reliable system that is independent
of connection to the ProxNet Controller.
The nonvolatile memory of both the ProxNet Reader and Controller ensures that
data is retained even if there is total power failure.
The ProxNet Controller is used to configure the system, manage tag holders,
and gather transactions. When the anti-pass-back or counters features are
used the controller must be online to make the access decision.
The user can manage the system and print basic reports via the 12-key keypad
on the controller. Enhanced management and reporting is available if a PC
running Windows software is connected onto the RS-485 network.

Access Levels
* Holders are assigned to one of 64 Access Levels.
* An Access Level is made up of a combination of any of the 8 time zones and
64 Areas.
* Time zones TZ1 - TZ7 are defined by a start time, stop time and valid days
of the week.
* Time zone TZ8 is linked to the TZ8 switch input on the ProxNet Controller.
Operation of this switch will bar all access except for those Holders set
for TZ8 access.
* The access level tables are stored in the reader ensuring a secure system
even if communications with the controller fail.
Anti-Pass-Back (APB)
If APB is implemented, a Holder will not be allowed access if their current
area (stored in the controller) is the same as the area to which they are
trying to gain access. This decision is made in the controller and if communications
with the controller are lost, APB checks cannot be carried out until such
time as communications are restored.
Three levels of APB can be implemented :
* Soft APB only checks when access movements are from a lower to a higher
area (increasing area number) and ignore APB when moving from a higher to
a lower area number.
* Hard APB checks all movements.
* Timed APB applies anti-passback for a defined period (e.g. 15 minutes) after
the last movement.
Event Counters
Individual holders may be assigned an event counter which can be set to count
up or down on each valid transaction.
The up counter may be reset to any value and will count up to a maximum count
of 65535 after which the count will not increment. Access is still allowed
after the maximum count is reached.
The down counter may be preset to any value up to 65535 and will decrease
to zero after which the holder will be denied access.
