“Point-to-Point Protocol” on page 4-5 explains the command formatting in detail.
Table 3-2 shows the command syntax and the code to switch on the 1555’s buzzer.
Table 3-2 Command Syntax
Configuration Commands
There are currently more than 350 configuration commands for Intermec data capture
products (EasySet shows the set of commands for each product, the command string is
displayed beneath commands selected for printout).
For the 1555, and in particular for the RFID parameters, additional configuration
commands are required (e.g., AIM identifiers for RFID data, custom identifiers for
RFID data, Auto Read parameters, and Auto Write parameters).
Interactive Commands
The operator can use the interactive mode to control the 1555 remotely by sending
configuration commands and interactive commands through the main
communications port.
These commands are used to control the basic functions of the internal peripherals
(LCD, buzzer, LED, RAM, and RFID module).
Dialog with the Host System
Commands can be transmitted in different ways according to the context.
The point-to-point protocol (PPP) is an extension of the frame command format
(“Frame Format ” on page 4-5). This format uses delimiters and a checksum and
contains an extended TYPE field for increased application possibilities (e.g., message
acknowledgment, message transmission, compressed data, and download
applications). Multiple frames are supported for long messages.
Example of a configuration command:
Code 39 Minimum Length configuration (L = 10): \0D\42\5C\0A
Example of an IMC switching the buzzer on:
Buzzer ON for 64 ms: 0A\01\01\00\40
Start Setup Command Parameters
<IMC> <buzzer function> <ON, timeout 100 ms>
0x0A 0x01 0x01, 0x00, 0x64
