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.
6-2 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 interfaces 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.
6-3 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.
