Introduction; Rs-232C Interface Specifications - Fluke 5700A Series II Operator's Manual

6-1. Introduction

This chapter describes how to set up the RS-232C interface for remote control using
protocol similar to IEEE-488, or to print or transmit data from the calibrator. After you
set up the interface for remote control, refer to Chapter 5 for full details of remote
operation. This chapter provides all details on printing or transmitting data.
The calibrator's RS-232C interface is designed in accordance with EIA (Electronic
Industries Association) standard RS-232C. Through its RS-232C interface, the calibrator
can be remotely controlled, and it can transmit its internal calibration constant values and
other information to a printer, video-display terminal, or host computer.

6-2. RS-232C Interface Specifications

The RS-232C interface is configured as DTE (Data Terminal Equipment). A null-modem
cable with two female 25-pin subminiature D connectors must be used to connect the
calibrator to other DTE (Data Terminal Equipment) such as printers, video-display
terminals, or computers. Recommended cables are Fluke accessories Y1702 or Y1703.
The pinout for the calibrator's RS-232C Connector is shown in Figure 6-1. The choices
available and the defaults for all programmable interface parameters are shown in
Table 6-1.
