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.
3.1 Keyboard Wedge Interface
3.1.1 Keyboard 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)
3.1.2 Keyboard 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.
3.1.3 Keyboard 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.

3.1.4 Capital 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.
3.1.5 Alphabets 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.
3.1.6 Digits 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.
3.1.7 Inter-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.
