MICRSafe with 3-Track MSR
14
•
If a multiple error condition occurs, the error or status code with the highest priority is
reported.
•
All unreadable MICR characters are transmitted as an “?” ASCII character (hex 3F), except
for Format 00xx (See Appendix A).
SWC - SWITCH C COMMAND
The SWC command controls miscellaneous functions, shown in Table 4-5. The data for
this command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
To execute, send the SWC command as follows:
SWC01010101<CR>
(with data)
or
SWC<CR>
(without data)
When sending data, all 8 bits must be provided. The MICRSafe will execute the
command but it 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 MICRSafe responds with the current settings for SWC.
