Welch Allyn SCANTEAM 6920 - Manual (Page 11)

6 SCANTEAM 6920 User’s Guide
Configuration Options: Dip Switch Controlled
The SCANTEAM 6920 contains a Dual InĆLine Package (DIP)
switch pack which is used to configure the operation of the
reader. The position of these switches are preĆset by Welch
Allyn, and normally do not need to be changed by the user. It is
only when the SCANTEAM 6920 is attached to certain
XTĆATĆPS/2 clones that you may need to change these settings.
The DIP switches on the SCANTEAM 6920 control the following
host interface parameters:
“SS” and “ES” characters
This parameter allows the SS" and ES" characters encoded
on the magneticstripe to be transmitted or not transmitted to
the host PC.
Carriage Return (CR)
This parameter allows transmission of a CR character (or no
CR) after each track or all tracks of data sent by the MSR.
Host Keyboard Scan Code Selection
This parameter allows the 6920 to be set to output either XT"
type keyboard scan codes or AT"type keyboard scan codes.
Keyboard Speed
This parameter allows the scan code transmission speed to be
set at either 25 or 80 characters per second (C/S). Many early
PCs and PC clones cannot support 80 C/S scan code speeds and
must be set to 25 C/S.
Upper / Lower Case
The data encoded on the magnetic stripe usually contains only
upper case characters. If the host PC's Caps Lock" key is set,
the host PC will misinterpret the data from the 6920 as lower
case. A DIP switch setting allows the 6920 to sense the state of
the Caps Lock key and automatically transmit the data such
that the host PC always receives upper case characters.
In order to access the DIP switch pack, the DIP switch cover
must be removed, exposing the switches.
Caution: Always turn power to the host PC off before connecting,
disconnecting, and/or changing DIP switch settings.
