6 RS-232 Remote Operation

6.1

Introduction

Section 6 describes how to operate the meter via standard RS-232
interface. It also explains the detail information of all RS-232 interface
command sets used in the meter. The remote control operation enables
the user either to manually operate the meter via a terminal or executes a
host computer program automatically.

RS-232 Interface Overview

The port serial contains of D-type 9-pin male connector on rear panel of
the meter is used to communicate the meter with a host computer, or
terminal via RS-232 standard interface. Figure 6-1 shows the RS-232
connecting diagram between the meter and a host computer.
RS-232 interface is a serial binary data interchange, which operates from
300 to 9600 baud rate And the distance between any two RS-232 interface
can be extended up to 50 feet. RS-232 port of the meter is designed in full
duplex, which makes the meter more reliable and efficient in data taking.

RS-232 Interface Parameters Set up

In order to operate the meter via a host computer or terminal, the parameters in
RS-232 interface within the meter has to match the parameters in the serial
interface provided by the host or terminal.
The following procedures will guide the user to set up RS-232 interface
parameters within the meter to comply RS-232 interface with the host. The
default settings of the meter at factory are 9600-baud rate, non-parity, 8 data
bits, and 1 stop bit (9600, n, 8, 1).
Table 6-1 indicates the factory settings and user selectable communication
parameters by using RS-232 interface.
