6 SCANTEAM 6980 User’s Guide
Configuration Options:
Dip Switch Controlled
The SCANTEAM 6980 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, unless the
host device's RSĆ232 communication parameters do not match
the SCANTEAM 6980's default settings (see page 8).
The DIP switches on the SCANTEAM 6980 control the following
host interface parameters:
“SS” and “ES” characters
This parameter allows the SS" and ES" characters encoded
on the magnetic stripe to be transmitted or not transmitted to
the host PC.
RS-232 Data Bit and Parity Selection
This parameter allows you to change the MSR's serial RSĆ232
output parameters for character data bit count and parity.
The following selections are available:
•
8 data bits and no parity,
•
7 data bits and even parity, or
•
7 data bits and odd parity.
RS-232 Baud Rate Selection
This parameter allows you to change the MSR's serial RSĆ232
output parameters for baud rate. The following selections are
available:
•
1200 bps (bits per second),
•
2400 bps,
•
9600 bps, or
•
19200 bps.
Check Sum Selection
This parameter allows transmission of a checksum character
(or no check sum) after the track data sent by the MSR.
In order to access the DIP switch pack, the DIP switch cover
must be removed, exposing the switches.
