Command protocol

Each device has a well-defined protocol for communication. The protocol can be split into two parts:

• General command/response-type communication

• Barcode decoding

9.1

General commands

Most of the time, the user will use the command protocol when communicating with the device. The figure
shows the general command sequence for sending a command to the device.

Fig. 9.1:

General command sequence

• The host device sends a properly formatted command to the device.

• The device sends an acknowledgement to the host device.

• Immediately after the acknowledgement, the device sends a response to the command.

• To maintain communication integrity, the host device sends an acknowledgement back to the device.

9.1.1

Command packet

To send a command to the device, a properly formatted packet must be formed.

Tab. 9.1:

Command packet format

Section

Bytes (or Range) Number of

Bytes

Description

Start of Frame

0x01

0x43

0x54

3

Three bytes that indicate the beginning of a
message

Packet Version

0x31

1

Indicates the version number for the packet
format. This value is always 0x31.

Packet Length

0x0013 – 0xFFFF 2

Indicates the number of bytes that are sent
after these two bytes, up to and including the
CRC. This value should be 19+N.

This value is written as a 2-byte big endian
value.

Destination Address

0x00000000 –
0x0FFFFFFF

4

Represents the address of the device that
you are attempting to communicate with.

0x0FFFFFFF is a special address indicating
that the host device wants to broadcast to all
devices on the network. Anything less than
this value is a real device address.

This value is written as a 4-byte big endian
value.
