Isotech TTI-7-R, Operator'S Handbook Manual

7.1 Introduction
The TTI-7-R can be fitted with one of the following types of
communications interface card:
RS-232 serial communications interface
or
IEEE-488 parallel communications interface
The optional communications interface lets you assign remote control
of the TTI-7-R to an external computer. The computer can also read
the measured value and instrument status.
Alternatively you can use the communications interface to log data
directly to a serial printer. See Section 5.5.2 for further details.
The cards plug directly into the instrument's main PCB assembly,
with the interface connector accessible on the rear panel. Interface
cards may be retro-fitted at any time. The TTI-7-R 's software
automatically detects the type of interface card fitted at power-up. The
control parameters for the communications interface can be set from
the front panel.
The interface instruction set is common to both interfaces and
generally follows the IEEE488.2/SCPI protocol.
