Packet structure

TSIP packet structure is the same for both commands and reports. The packet format

is <DLE> <id> <data string bytes> <DLE> <ETX>

Where:

•<DLE> is the byte 0x10

•<ETX> is the byte 0x03

•<id> is a packet identifier byte, which can have any value except <ETX> and

<DLE>.

The bytes in the data string can have any value. To prevent confusion with the frame

sequences <DLE> <id> and <DLE> <ETX>, every <DLE> byte in the data string is

preceded by an extra <DLE> byte ('stuffing'). These extra <DLE> bytes must be added

before sending a packet and removed after receiving the packet. A simple <DLE>

<ETX> sequence does not necessarily signify the end of the packet, as these can be

bytes in the middle of a data string. The end of a packet is <ETX>, preceded by an odd

number of <DLE> bytes.

Floating point numbers (single, double) follow the IEEE Standard for Binary

Floating-Point Arithmetic (IEEE 754.) Multiple-byte numbers (integer, single and

double) are sent most-significant byte first.

Note – On Intel-based (little-endian) machines you must switch the byte order.

The data types used in TSIP are as follows:

Note – Default serial port settings are 9600, 8-None-1.

Data type Description

UINT8 An 8-bit unsigned integer (0 to 255)

SINT8 An 8-bit signed integer (-128 to 127)

INT16 A 16-bit unsigned integer (0 to 65,535)

SINT16 A 16-bit signed integer (-32,768 to 32,767)

UINT32 A 32-bit unsigned integer (0 to 4,294,967,295)

SINT32 A 32-bit signed integer (-2,147,483,648 to 2,147,483,647)

Single Single-precision float (4 bytes) (1.2x10-38 to 3.4x1038)

Double Double-precision float (8 bytes) (2.2x10-308 to 1.8x10308)
