NXT Reader Setup
NXT Readers are used exclusively with Keri's revolutionary access control system
based on the NXT and the MSC Series of IP-based Controllers. Communication to the
readers is via the controller's RS-485 buses, enabling the data to be encrypted and
allowing the readers to be fully supervised - reader events will be generated in the event
of reader failure or disconnection
- (these reader 'offline' events can be setup as 'alerts' in the software).
Another NXT reader benefit is the fact you can add an NXT Exit reader (supported with
the NXT-MSC controllers). The Exit reader is added to the same bus as the standard
NXT reader but provides you with true In/Out reader capability without burning an addi-
tional reader port. Even though the readers are wired into the same bus they show as
independent readers within Doors.NET allowing you to control 4 x read IN and 4 x read
OUT doors with a 4-door controller.
The RS-485 communication method also allows for a maximum cable run distance of
1,000 feet (approx. 300m) from the controller. The readers are compatible with all NXT
Series cards and tags plus the readers can now be configured to read HID 125KHz cre-
dentials via a quick firmware upgrade which can be easily performed from the software.
This guide explains how to connect the readers to the controller, how to perform a firm-
ware upgrade, program the reader to read HID credentials and how to add and use an
NXT Exit reader.
