Remote Operation
Introduction 3

Introduction
Remote operation of the Product from a computer is done with commands through the
RS-232 digital interface or a serial USB interface. To control the Calibrator remotely, the
computer sends SCPI (Standard Commands and Programmable Instruments) commands.
These commands let the user change and control all parameters remotely such as
SETPOINT temperatures, cutouts, and programs.
This chapter supplies information on how to set up the remote connection to the PC,
followed by command line information.
Remote Operation Setup
The Calibrator has an RS-232 and USB interface on the Power and Remote Interface
Panel (see Table 3-1).
Note
To prevent noise on the signal wires, use a shielded, low resistance cable
between the Product and PC.
