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.
Invalid Command Response
Invalid command response is the action the MICR Reader takes upon receipt of a
command it does not recognize. It can also be used to stop the MICR Reader from
receiving any more commands.
The first option “
?<CR>” is the default. If the MICR Reader receives an unrecognized
command, it will return a question mark and carriage return to the Host. The MICR
Reader will then return to an idle state and wait for further commands or check/credit
card reads.
For the second option, “no reply - header required,” the MICR Reader will only execute
commands preceded by a GS ASCII character (hex 1D). All other commands will be
ignored. Also, the MICR Reader will not reply to invalid commands.
For the third option, “no reply,” the MICR Reader will execute all valid commands, but it
will not reply to invalid commands.
The fourth option, “ignore all commands,” causes the MICR Reader to ignore any further
commands. Even the SA (Save) command is ignored and therefore this fourth option is
only temporary. To make this option permanent or to reset it, you must use an Insta-
Change check.
Active RTS
When this function is set to YES, the MICR Reader will raise RTS and wait 5 seconds
for CTS to become active before sending any data. If the 5 seconds expire and CTS is
not active, the data message will be discarded and nothing will be sent
