This chapter explains how to use the IRL editor and how to enter, change, and store
IRL programs. Sample programs are included: two for using the sense inputs/output
relays and one for controlling the optional magnetic card reader. There is also a
description of commands for the magnetic card reader.
Introduction to IRL
You use Intermec’s Interactive Reader Language (IRL) to develop custom
programs for the 9560. You can use the reader’s built-in IRL programming
capability, or you can develop programs on a DOS-based computer. Contact
your local Intermec dealer for information on PC-IRL (for DOS) or Collect
™
(for
Windows).
You can enter IRL programs in several ways:
• Scan bar-coded program statements with a wand or scanner
• Enter the commands from a CRT terminal or 1700 keyboard
• Enter most of the commands from the 9560 keypad
• Download the program file from the host computer
You can store programs in the reader’s memory (256K RAM) or in the host’s
memory for downloading later to the reader. Also, you can copy a program in
one reader into another reader. IRL programs are limited to 52K, including
comments.
This chapter includes three sample programs and a table of the IRL bar codes
referenced in this section. For a more detailed explanation of IRL, refer to the
IRL Programming Reference Manual (Intermec Part No. 048609). Any commands
that are exclusive to the 9560 are described in “Unique IRL Commands for the
9560” in this chapter.
Note: The 9560 supports IRL version 2.1. Later versions, such as IRL 2.2 and
IRL 4.0, contain commands that the 9560 does not support. See “Unique IRL
Commands for the 9560” later in this chapter.
