MAXI MICR RS232 with 2-Track MSR

Comm Mode 7, also known as Packet Mode, calculates an LRC (Longitudinal Redundancy
Check), and appends it to the data message. Also, if a <NAK> (hex 15) character is received in
this mode, the MICR Reader will resend the last message.
Send Data After Error
The request Send Data After Error specifies whether the MICR Reader will return data to the Host
after a read error. If YES is selected and the MICR Reader detects a read error, the MICR Reader
will still send the data back to the Host. If NO is selected and the MICR Reader finds an error, it
will discard the data and nothing will be sent. The error conditions are listed in Table 4-4.
Send Status After Data
The Send Status After Data option makes the MICR Reader append a two-digit error/status code
to the end of the MICR data. For most formats (See Appendix A), the error/status code will
always be preceded by a forward slash (/). The error/status codes are listed in Table 4-4.
For example, if a Canadian check (code 08) is read and had no errors, and the MICR data is
“1234567890”, then the message from the MICR Reader will look like this:
MICR Data: 1234567890/08
The status code is always at the end of the data, not the end of the message. For example, using
the above conditions, with the message format set to send <STX> and <ETX>, the message from
the MICR Reader will look like this:
MICR Data: <STX>1234567890/08<ETX>
