Chapter 3 — Principles of Operation

3.1 Entering from Intermec Shell

In Intermec Shell, select the "Intermec Direct Protocol" option under the
"Select Application" headline. After a few seconds, the display will show
the message:
Direct Protocol
7.80

3.2 Entering from Immediate Mode

If you want to enter the Direct Protocol from the immediate mode of
Intermec Fingerprint, issue the following instruction:
INPUT ON ↵
The display will show the message:
Direct Protocol
7.80
By default, no messages or characters will be returned to the host (see
Chapter 6.15) until you leave the Intermec Direct Protocol.

3.3 Special Intermec Direct Protocol Features

If you are familiar with Intermec Fingerprint, you will notice that the
Intermec Direct Protocol is rather similar to the Immediate Mode. There
are, however, some important differences:
• The Intermec Direct Protocol has a built-in error handler, that can
indicate selected error conditions and produce error-messages of your
own creation in any language you like.
• The Intermec Direct Protocol is able to receive variable input data in a
special format to fi elds in a predefi ned layout.
• The Intermec Direct Protocol allows you to create counters without
extensive programming.
• The Intermec Direct Protocol provides a simple way to enable the
Print key to produce printouts.
• By default, verbosity is off in the Intermec Direct Protocol. While you
develop your Direct Protocol fi les, we recommend setting the verbos-
ity to ON using a SYSVAR (18) instruction, see Chapter 6.15
