MICRSafe with 3-Track MSR

SWB PARAMETERS

The SWB functions are listed in Table 4-2 above and are described below:

Control Characters and MICR Data

Control Characters may be added to MICR Data messages. The MICRSafe will insert
any control characters selected using this command into outgoing formatted MICR Data
messages in the following sequence:
<STX> <ESC> data <ETX> <CR> <LF>
The control characters, descriptions, and hex values are shown in Table 4-3.
For example, if the <STX> and <CR> options are set to YES, a MICR Data message
from the MICRSafe will look like this:
MICR Data: <STX>data<CR>

Control Characters and Card Data

If the card reader's head is set to security level 2, then the same control characters may
also be added to Card Data messages, but they are applied to each track individually. For
example, if the <STX> and <ETX> options are set to YES, a Card Data message from the
MICRSafe will look like this:
Card Data: <STX>[TK1 data]<ETX><STX>[TK2 data]<ETX><STX>[TK3
data]<ETX>
Please note again that card reader heads that are set to security level 1 and 3 do not support this control
characters.

Communication Modes

The selection of Comm modes is a quick way of selecting multiple Control Characters.
For instance, to send a carriage return/line feed pair after the data, you can specify Comm
Mode 3.
