Comparisons Between the PS/2 and USB Keyboards
Overview
The NCR 5932 USB Keyboard is a replacement for its predecessor, the
5932 PS/2 (wedge), with features and advantages not present in the
older product. This section is a discussion of those features with some
explanation of the advantages.
Summary
The NCR 5932 USB keyboard improves on its predecessor by taking
advantage of features of USB to increase flexibility and connectivity.
The major advances are:
1.
Glide Pad integration
2. Full keyboard re-programmability
3. Added general-purpose connectivity via on-board USB port
4. Future optional fingerprint sensor module
There are also minor technical improvements, primarily a benefit for
systems integrators. One example is the ability for host software to
detect the presence or absence of the MSR, Keylock, and Glide Pad.
Another example is the use of standard USB protocols throughout and
even standard USB Human Interface Desine (HID) device classes
where such device standards exist. NCR went so far as to help develop
an additional standard in the case of the MSR. Use of such standards
eases the job of systems engineers and integrators.
