TC300 Heater Temperature Controller Chapter 8: Command Line Operation

Chapter 8 Command Line Operation
8.1. Command Line Overview
The TC300 can be controlled by a command line through the USB or RS232 port, as a virtual COM device. This is
to enable operation through a terminal interface or for those who wish to write their own program to control the unit.
The command-line language is described below. Prior to running the command-line interface, the included drivers
should be installed, the unit should be powered on, and a USB cable should be connected between the TC300
controller and the host PC.
The terminal emulator should be configured as follows:
Baud Rate: 115.2 kbps
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
The basic structure of the interface is a keyword followed by either an equal sign (=) or a question mark (?).
The = or ? character determines if the string is a command or a query. All strings, commands, and queries must
be terminated by a carriage return (CR).
The command structure is as follows:
Keyword=argument(CR)
where “keyword” defines the function and “argument” is a numerical value followed by a carriage return (CR).
Notice that some commands might have more than one argument, separated by a space character.
The query structure is as follows:
Keyword?(CR)
where “keyword” defines the function and the question mark (?) indicates a query. The string is terminated with a
carriage return (CR).
There are a few exceptions to this which are noted below. The following table lists the commands and queries
available with this device as well as unique shortcut keys. The prompt symbol (>) appears after each command is
accepted by the controller indicating it is ready to receive the next command.
If the command is incorrect, the controller returns CMD_NOT_DEFINED; if the setting value is out of range, it returns
Data Out-Of-Range!
