Configuring the RS-232 Port
The RS-232 Communication Interface allows ASCII, asynchronous, serial
communication between the Meter and a host or terminal. The following sections
describe the process of configuring the RS-232 port. To make the RS-232 port the active
port for remote operation, see the "Selecting the Remote Interface Port" section above.
Table 3 lists the RS-232 parameter settings when the Meter leaves the factory.
Baud Rate
Parity
Number of Data Bits
Number of Stop Bits
Flow Control
To access the RS-232 setup menu:
1. Press I.
2. Press the PORT IF soft key.
3. Press the RS232 soft key.
All RS-232 port parameter settings are non-volatile and remain set until
changed.
Setting RS-232 Baud Rate
To set the baud rate:
1. With the RS-232 set up menu displayed, press BAUD RATE.
2. With the desired baud rate displayed, press the soft key under the chosen baud rate.

Parameter
At this point, all the RS-232 settings are made available.
There are eight pre-defined settings: 1200, 2400, 4800, 9600, 19200 38400, 57600,
115200, and 230400. These selections are displayed in two separate menus. When
first entering baud rate selection, baud rates 9600 to 1200 are displayed. To get to the
next five higher baud rates, press MORE. To get back to the lower baud rates, press
B.
