3.Output Interface

The Pulsar C is a single interface CCD scanner. It can be ordered as a keyboard wedge scanner, and a RS-232 scanner. The output interface must be specified at time of order.

3.1Keyboard Wedge Interface

3.1.1Keyboard Type

The keyboard wedge interface is enabled by configuring/selecting keyboard type. The supported keyboard types are listed below.

•PCAT - US, French German, Italian, Swedish, Norwegian, UK, Belgium, Spanish, and Portuguese KBD

•PS2-30

•IBM 3477 TYPE (Japanese KBD)

•IBM 34XX,319X & Memorex Telex (122Keys)

3.1.2Keyboard Style - Alphabets

Keyboard layout style can be selected. There are three options to this setting : default layout (US or English style), AZERTY layout, and QWERTZ layout. This setting only works when the keyboard type selected is for US keyboard. The scanner will make necessary adjustment when sending the ‘A’, ‘Q’, ‘W’, ‘Z’, ‘Y’, and ‘M’ character according to this setting.

3.1.3Keyboard Style – Digits

There are two digit layout styles as shown on the following figures. One has its digit keys on top (upper row), the other has them on bottom (lower row).

Configuring this setting can change the layout of the digits. There are three options: Default, Lower Row, and Upper Row. The scanner will make necessary adjustment when sending digits according to the setting value of this parameter. This setting is meant to be used with the above setting (Keyboard Style – Alphabets) and perhaps Character Substitution setting, when support to languages not available on the scanner is needed.

3.1.4Capital Lock Status

In order to send alphabets with correct case, the scanner needs to know the capital lock status of the keyboard. Incorrect settings may result in reversed case of alphabets being transmitted. There are 3 options to this parameter : On, Off, or Auto Detection. If this parameter is set to Auto Detection, the scanner will automatically detect the capital lock status of the keyboard before it transmits data.

3.1.5Alphabets Transmission

User can choose how alphabets are sent by configuring this parameter. The alphabets can be sent according to their case (the Case Sensitive option), or the case is ignored (the Ignore Case option) when transmitting.

3.1.6Digits Transmission

User can choose how the scanner transmits digits by configuring this parameter. The scanner can transmit digits by using the alphanumeric key or by using the numeric key pad. The Num Lock status of the keyboard should be ON if numeric key pad option is selected.

3.1.7Inter-Character Delay

An inter-character delay of 0 to 255 ms can be configured to match the computer response time of the keyboard interface. The delay time configured is inserted between transmitting every character. The longer the delay time configured, the slower the transmission speed will be. The inter- character delay is zero by default.
