Magnetic Card Reader Configuration
The way in which the magnetic card reader handles the data header affects the
configuration file. Some card readers include the data header when the records are
read. Others strip it out. You need to account for this difference when you define
Offset
and
Total Bytes
in the magnetic card reader’s configuration file.
Use the following procedure to identify how the magnetic card reader handles the
data header:
1.
Connect a magnetic card reader to a PC.
2.
Run
Microsoft Notepad
or some other ASCII text editor.
3.
With
Notepad
active, swipe a magnetic card through the card reader.
The information on the card is displayed in
Notepad
.
4.
Examine the record in
Notepad
.
• If the first character is a semi-colon, the card reader includes the data header.
The
Offset
of each field and the
Total Bytes
of the configuration file need to
be increased by 1.
• If the first character is alphanumeric, the card reader strips the data header.
Configuring the Magnetic Card Reader
You configure the magnetic card reader on the system’s
Patient Setup
window (refer
to
“Patient Setup” on page 109
). To configure the card reader for the example in the
introduction, enter the information shown in the following table.
Field
Offset
Length
Patient ID
1
6
First name
7
13
Last name
20
10
Year of birth
34
4
Month of birth
32
3
Day of birth
30
2
Gender
38
1
Total bytes:
39
Offset is the number of characters to the left of the field, not the field’s starting
position. To calculate the Offset, add the Offset and Length of the preceding field in
the record. For example, the Offset of
First Name
is 7, which is the
Patient ID
Offset (1)
plus the
Patient ID
Length (6).
NOTE:
Patient ID
has an Offset of 1 because it is preceded by the single character data
header. If the magnetic card reader stripped the header from the record, the
Patient ID
Offset would be 0, and all subsequent Offsets would shift accordingly.
Total Bytes is the sum of all the field lengths in the record. If the card reader includes
the data header, Total Bytes is the sum of all field lengths plus the data header. In
this case, the sum of all field lengths is 38. You need to add a length of one for the
data header and the Total Bytes is 39.
