FOT Lab Kit User’s Manual 4-1
4 User Interface Commands
The primary user interface with the FOT Lab Kit is through a
standard RS-232 serial interface. The host may be a standard
terminal emulation application software such as HyperTerminal™ or
a custom device-control program communicating through the RS-
232 interface. LUXTRON also offers a Windows-based graphing and
data-acquisition program for PCs called TrueTemp™.
The instrument communicates at 9,600 bits-per-second. The bit
protocol is 8 data bits, one stop bit and no parity (8-N-1). The
instrument does not use a handshaking protocol. The details of the
communication protocol are defined in this chapter and Chapter 5,
“Temperature Data Reporting” .
User interface commands fall into two general categories:
1. Parameter Commands: Two-letter command codes with
required or optional arguments.
2. Action Commands: One-letter character command codes
consisting of the Control key plus one letter key.
For a summary of the Parameter Commands, see Table 4-1 on
page 4-5. For a summary of the Action Commands, see Table 4-2 on
page 4-5.
