Chapter 6: Commands

MICR Check Reader Commands

These commands control the Magnetic Ink Character Recognition (MICR) check reader,
including how it parses the character strings on checks. The remainder of this chapter
explains these commands.
The section that follows, "MICR Parsing," describes how to create a parsing format and
how to create and maintain an exception table. If you would like a copy of a software
utility that performs these functions rather than developing your own program using the
command codes described in this section, please contact NCR. The software utility can be
used as provided or can be incorporated into your own application.

Read MICR Data and Transmit

Reads and transmits the MICR data and adds a Carriage Return (0D). This command must
follow Select Receipt or Slip for Printing, Slip for MICR Read (1B 63 30 n). If no parsing
format is selected with either of the Define Parsing Format commands (see below), all data
will be returned, which is the default.

Define Parsing Format, Save in NVRAM

Defines and saves parsing format. See "Parsing Parameter String Options" on the next
page. Send this command at the start of day or use in the setup application. If no
parameters are selected, parsing is not performed.

Reread MICR Data

Resends the unparsed MICR data (as if the parsing has not been defined).

Define Parsing Format, Do Not Save Permanently

Defines, but does not save parsing format. See "Parsing Parameter String Options" on the
next page. Send this command at the start of day or use in the setup application. If no
parameters are selected, parsing is not performed.
