Chapter 5: 5953 USB DynaKey Migration 5-9
The USB DynaKey implements the MSR as a separate USB HID device,
conforming to the published HID standard for MSR devices. As with
the keylock, the PnP feature of USB communications makes it a simple
matter for the host computer and thus the customer’s application to be
aware of the presence or absence of the MSR.
Scanner port
The Wedge DynaKey contains an NCR-proprietary RJ-45 connection
for RS-232 based scanners. This port has several technical limitations,
and a limited subset of NCR scanners are qualified.
The USB DynaKey has no RJ-45 connector for RS-232 scanners. But see
Additional Ports, below.
Additional ports
The Wedge DynaKey has no additional ports beyond the Scanner port.
The USB DynaKey provides three standard self-powered USB ports.
These connections allow a USB scanner, or for that matter, any
standard USB device to be connected through the DynaKey to the host
computer.
Power LED
Both the Wedge and USB DynaKeys have an LED that indicates when
power is present.
Fingerprint Sensor
The USB DynaKey has been designed to accommodate a fingerprint
sensor module. This module replaces the keylock module, and operates
as another independent USB device through the internal hub. The
Wedge DynaKey does not have this capability.
