MINI MICR WEDGE with 3-Track MSR
16
When sending data, all 8 bits must be provided. The MICR Reader will execute the command but
will not reply. The new settings become effective immediately. To make this command
permanent, use the SA (Save) command described at the end of this section.
If no data is sent, the MICR Reader responds with the current settings for SWC.

SWC PARAMETERS
The SWC functions are listed in Table 4-5 and described below.
CMC-7 Character Set
If NO is selected the MICR Reader will only read E13-B characters. When YES is selected, the
MICR Reader will read both CMC-7 and E13-B characters (see Appendix B). However, the
MICR Reader will only output raw data ("as is" on the check) for checks with CMC-7 characters.
Card Data Message
This option determines the structure of the output message for the individual tracks when a credit
card is read. If Multiple is selected, the Control Characters (see SWB, below) and Data Header
(see Data Header, above) are added to each track individually. On the other hand, if Single is
selected, all available tracks are lumped together into a single message. For example, if <STX>,
and <ETX> are set to YES, the output message may be transmitted as follows:
If Multiple Message:
<STX>[TK1]<ETX><STX>[TK2]<ETX><STX>TK3]<ETX>
If Single Message:
<STX>[TK1][TK2][TK3]<ETX>
