Setting Up Serial
Communications
1-46
The Model DF868 flowmeter can transmit stored data and displayed
readings to a remote ANSI terminal or a personal computer by
connecting the meter's RS232 interface to the serial port of the PC. In
addition, the Model DF868 can receive and execute remote
commands using this link. The meter can also be configured with a
MODBUS option card for MODBUS communications, a Foundation
Fieldbus option card for Foundation Fieldbus communications, an
Ethernet option card for Ethernet communications, or with a
MODBUS/TCP option card for MODBUS communication over the
Ethernet, if desired.
Note: To set Fieldbus communications parameters, see Appendix D,
Foundation Fieldbus Communications.
COMM
Use the submenu to set the RS232, MODBUS, Ethernet and
MODBUS/TCP communications port parameters and to enter a
network identification number. A network identification number is
required to use the GE Instrument Data Manager or PanaView
software. While following the instructions, refer to Figure A-5 in
Appendix A, Menu Maps.
COMM
1. Enter the submenu by pressing [→] and
User Program screen.

2. Use the and [→] keys to select the desired Baud Rate.
Note: As shown in Figure A-5, the available rates are 300, 600,
1200, 2400, 4800, 9600 and 19200 baud.

4. Enter a Network ID number between 1 and 254 and press
The default number is 1.
A network ID number is only necessary for communication with the
GE Instrument Data Manager (IDM) or PanaView software. See the
software User's Manual (910-185) for more information.
IMPORTANT:
If the network ID number is changed, communication
with the Instrument Data Manager or PanaView must
be re-established with the new ID number.
