Chapter 1: General Overview

Introduction

This document covers the Universal Serial Bus (USB) version keyboard

Point-of-Service (POS) for the NCR 5932. Also discussed is a

comparison between the older 5932 PS/2 and the 5932 USB keyboards.

109 Key USB Keyboard

19586

The 109-key USB keyboard is a multifunction keyboard that is two

keyboards built into one.

The keyboard consists of two major sections:

• 38-key POS keyboard

• Industry-standard alphanumeric PC keyboard

The keyboard contains the key matrix and other POS-specific functions

such as Keylock, speaker, system status indicator, and magnetic stripe

reader (MSR). This 5932 keyboard also has a USB port to connect a

Scanner or other USB device.

Features

The NCR 5932 USB Keyboard supports the following features:

• Keylock

• Speaker

• Magnetic Stripe Reader (MSR)

• Keyboard Status LEDs

Keylock

The USB keyboard has a four-position Keylock. You can rotate the

Keylock between specific positions by use of three keys. The positions

are explained in the following table.

Abbreviation Position Description

Ex Exception Used by the customer or service

representative to perform low

level programming such as

workstation diagnostics,

configuring the workstation, or

loading the workstation.

L Locked Used to lock keyboard input to

prohibit use of normal functions.

R Register Used when performing normal

retail mode functions.

S Supervisor Used by the supervisor to

provide highest level of

workstation control in cases such

as refunds and running totals.

Speaker

The programmable speaker is capable of generating key clicks and

error tones.

1-4 Chapter 1: General Overview

MSR

The MSR is an optional feature that provides support for reading

magnetically coded data cards. The keyboards support two different

types of MSR:

• ISO Tracks 1, 2, and 3

• JIS-II and ISO Track 2

The MSR head is connected to the MSR Amplifier Assembly via the

MSR connector. The MSR Amplifier Assembly contains the

amplification circuitry, a PCB, cable, and connectors.

The MSR Amplifier Assembly is connected to the main PCB and

mounted internally into the keyboard housing by the supplier on every

unit. The intent is that when it becomes economically reasonable the

MSR Amplifier Assembly (with modification) would be added the to

MSR read head assembly kit and installed by the assemblers only when

the customer requested the MSR option.

Keyboard Status LEDs

The keyboard has three status LED’s:

• Num Lock

• Caps Lock

• Scroll Lock

These features are used to provide the present state of the keyboard.

The indicators are single color (Green) LED’s. When the system is off,

no LED’s are illuminated.

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.

1-6 Chapter 1: General Overview

Discussion

The NCR 5932 line of keyboards contain, most basically, a set of keys in

a physical configuration that has been found useful to retailers. The

keyboards also come with additional features, some optional, that add

value to the retail environment. The following table lists these features.

Chapter 1: General Overview 1-7

101-Key style keyboard

The foundational difference between the NCR PS/2 keyboard and the

NCR USB keyboard is the communications between the keyboard and

the host computer. The PS/2 keyboard communicates using the PS/2

communications protocol, which is bit-serial and operates at

approximately 25 Kb. The USB keyboard uses the USB 1.1 protocol,

which is a different bit-serial protocol that operates at either 1.5 or 12

Mb. NCR’s keyboard operates at 12 Mb except for the Glide Pad, which

operates at 1.5 Mb.

Furthermore, each of these protocols includes a software layer. The

PS/2 software layer is very simplistic, and presents a challenge when

adding additional capabilities beyond the keyboard itself. All the

added devices, such as MSR, Keylock, tone, and scanner are

implemented as wedge devices. This means that these devices are

wedged into the keyboard data stream and must spoof their way past

the operating system to transfer data. This technique, though

widespread, is burdened with problems, and is not standardized,

resulting in installation and support difficulties.

The USB software layer is standardized and well defined. It supports

multiple simultaneous channels of communications, and permits

additional capabilities to be added without negative impact.

Furthermore, USB defines several levels of standards, including a

standard for Human Interface Devices. This standard specifies

behavior for many devices that are widely used in the computer

industry, and permits proprietary extensions to be added for those

devices that are less widely used. NCR’s USB keyboard includes both

fully standard HID devices, such as the keyboard itself, the Glide Pad,

and the MSR, and less-widely used and thus customized HID devices

such as the Keylock and Error Tone.

The USB keyboard implements a standard USB Hub internally. This

hub provides independent connectivity to the several functional

sections that comprise the keyboard.

1-8 Chapter 1: General Overview

For many years, the standard in keyboards was the keyboard style

known as 101-Key. In recent years, with the broad acceptance of

Graphical User Interfaces, keyboards have added one or two GUI keys

and current keyboards are now called 102-Key or 103-Key style. The

NCR PS/2 keyboard does not contain these GUI keys. The NCR USB

keyboard does not have reserved positions for those keys, but permits

those keys to be added using the keyboard programmability (see

Keyboard Programmability).

Cappable Keys

Both USB and PS/2 NCR keyboards include keys that accept customer-

specified key caps and labels. For example, one customer may wish to

include buttons for DEPT, CLASS, and SKU on his keyboard. A

different customer may have no use for these keys, but may want

TIRES, BATTERIES, and ACCESSORIES on specific keys. Cap-able

keys allow for this customization.

Double-High / Double-Wide Keys

Along with cap-able keys comes the ability to put caps over pairs of

plungers, resulting in larger keys. On a standard keyboard, the space

bar, the Enter key, the Tab, Delete, Shift, Control, and Alt keys are all

wider than the rest. These keys are implemented with one or two

plungers, but they cannot be modified for different functionality. On

NCR keyboards, the cap-able keys may be capped in pairs. Key caps

are available that cover two plungers, either double-high or double-wide.

When two keys are capped individually, the keyboard firmware must

detect each one as a different key, and must send different messages to

the host computer to indicate different keys were pressed. When the

same two keys are capped together, the firmware must somehow know

this and send only one message.

Chapter 1: General Overview 1-9

With the 5932 PS/2, this is accomplished by using firmware that senses

both plungers and the time lag between the plungers. If adjacent

plungers are pressed within a certain interval, then the firmware only

sends one of the two. Which one it sends is fixed, and the time lag is

fixed. Thus, although this method works, it is subject to occasional

error due to small mechanical tolerance problems. It is also somewhat

limited in flexibility.

With the 5932 USB, the keyboard is fully programmable. Two keys that

are capped together can be programmed to literally BE the same key.

(Duplicate messages are discarded.) Thus there is no limit to the

flexibility, and no problem can be induced by the same minor

mechanical problems experienced with the 5932 PS/2 keyboard.

Keyboard Programmability

The 5932 PS/2 keyboard includes the ability to select whether the

keypad should be telephone- or calculator-style. This is implemented

with a simple toggle that selects which layout is to be selected. No

other programming is possible.

The 5932 USB keyboard includes full programmability of the keyboard.

Each and every key can be re-assigned as desired, and is only limited

by the capabilities of a standard USB-HID keyboard. Based on registry

entries, a program on the PC sends a complete keyboard layout matrix

to the keyboard firmware. From that moment on, the firmware sends

the newly assigned set of keys over the USB connection. No translation

software is required in the host PC.

New key values are assigned using registry entries. This means a

keyboard can be replaced in the field without any extra programming

steps. Once the terminal has been set up with key assignments, a

replacement keyboard will automatically receive the programmed key

assignments. Key assignments are sent from the registry whenever an

NCR USB keyboard is connected to the PC, whether at power-on or

hot-plugged.

1-10 Chapter 1: General Overview

Each key can be programmed to be a dead key, one single key, or a

two-key combination. Most keys will be single key values. However

some keys may be programmed as a two-key combination. For

example, the combination of Shift and F1 key values may be used to

provide compatibility with the 5932 PS/2 keyboard. A double-zero key

is another potential use for this feature. Any combination of up to two

key values may be assigned to a single plunger on the keyboard.

The registry values can be managed using a simple text editor along

with the operating system supplied registry editor. Alternatively, a

GUI utility (non-supported) is available for visually manipulating the

key assignments in the registry (see Key Re-mapping Registry

Manipulation Tool).

Keylock

Both PS/2 and USB keyboards include a four-position Keylock. All

PS/2 keyboards have a Keylock, whereas in the USB keyboard, it is

optional.

The PS/2 keyboard implements the Keylock as a wedge device. The

USB keyboard implements the Keylock as a separate HID device.

Because USB is designed for plug-and-play (PnP), the presence or

absence of the Keylock is easily detected by the host software.

In both keyboards, placing the key in the L (Locked) position disables

the keyboard. In the PS/2 keyboard, the MSR and the external scanner

port are disabled. In the USB keyboard, the MSR, the Glide Pad and the

external USB port are all disabled.

Key Click

Both PS/2 and USB keyboards provide a small speaker that can be

used to make a key click sound. The exact sound made for key clicks is

programmable in both devices, and the sounds available are

comparable.
