Gocator Line Profile Sensors: User Manual
Protocols • 571
The Gocator SDK provides open source C language libraries that implement the network
commands and data formats defined in this section. For more information, see GoSDK on page
665.
For information on configuring the protocol using the Web interface, see Ethernet Output on page 434.
For information on job file structures (for example, if you wish to create job files programmatically), see
Job File Structure on page 474.
Data Types
The table below defines the data types and associated type identifiers used in this section.
All values except for IPaddresses are transmitted in little endian format (least significant byte first)
unless stated otherwise. The bytes in an IP address "a.b.c.d" will always be transmitted in the order a, b,
c, d (big endian).

Data Types
Commands
The following sections describe the commands available on the Discovery (page 572), Control (page
575), and Upgrade (page 612) channels.
When a client sends a command over the Control or Upgrade channel, the sensor sends a reply whose
identifier is the same as the command's identifier. The identifiers are listed in the tables of each of the
commands.
