6.2 Packetized Commands

Packetized commands consist of packetized data sent from Host to Reader to configure and cause the

Reader to perform certain functionalities (e.g. CodeXML

rules, and settings). Packetized commands

are always enabled, unlike text commands. In addition, they include error detection data, making them

more robust than text commands.

normal-command: prefix command-type data-size data

opt

reserved crc14

prefix: 0xEE 0xEE 0xEE 0xEE

command-type: Single ASCII character in the set defined in Section 6.3

data: datum

| data datum

datum: any byte value in the range [0,255]

data-size: byte value in range [0,240], which indicates size of data (in bytes)

reserved: 0x00

crc14: two consecutive bytes, each in range [0,127], representing crc16 bitwise AND

with 0x7f7f, most significant byte first. The packet crc16 is calculated over the

entire packet, excluding the prefix and the crc14 itself. (See source files

crc16.[hc] (Appendix) for details on the crc16 algorithm and polynomials to be

used.)

6.3 Command Types

ESC

Reserved for use by JavaScript applications. This command can be used to notify

JavaScript functions from a B-String. No defined function in firmware or CodeViewer

JavaScript.

(The Reader will respond with d or e.)

Causes the Reader to beep and/or vibrate the specified number of times; data contains the

number as a single character in the range [0,127].

(The Reader will respond with d or e.)

Example – beep/vibrate three times: #%03

1 2 ... 8 9 10 11 12 13 14 15 16 17 18 ... 64 65
