CRB System

The CRB system is a convenient method for creating and maintaining a set of commands

that can be easily sent to the reader. These CRB files can be created in any text editor

with the file extension of .crb. The CRB system accepts all of the valid text commands.

The most commonly used commands are J, N, P, and ~. There should be one command

per line. The CRB file may contain empty lines and comments as well.

The .crb files can be sent directly to the reader using the normal file transfer. As CRB files

are just a list of text commands, they can also be sent by a serial terminal program. Note:

if using a serial terminal program the reader will first need to be set to “text command

mode”; see Text Commands.

You can request a copy of all reader configuration settings in .crb format.

Example CRC16 C Code

CRC16.h:

// crc16.h

#ifndef crc16_h

#define crc16_h

#include <stdint.h>

#include <stddef.h>

#ifdef __cplusplus

extern "C" {

#endif

typedef uint16_t crc_t;

crc_t crc

( crc_t initialCrc

, const unsigned char* bufPtr

, size_t length

);

#ifdef __cplusplus

} // extern "C"

#endif
