Digital Communication Interface
The furnace is capable of communicating with and being controlled by other
equipment through the digital serial interface.
With a digital interface the instrument may be connected to a computer or other
equipment. This allows the user to set the set-point temperature, monitor the
temperature, and access any of the other controller functions, all using remote
communications equipment. Communications commands are summarized in
Table 2.
9.1 Serial
Communications
The calibrator is installed with an RS-232 serial interface that allows serial digital
communications over fairly long distances. With the serial interface the user may
access any of the functions, parameters and settings discussed in Section 8 with
the exception of the BAUD rate setting.
