Setting Up Serial
Communications
1-44
The Model GC868 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 GC868 can receive and execute remote
commands via 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.

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 programming instructions, refer to the
menu map in Figure A-3 on page A-3. Enter the
[F3]
pressing [→] and at the initial User Program screen and complete
the following steps:
1. Use the [←] and [→] and
Rate. The available rates are 300, 600, 1200, 2400, 4800, 9600 and
19,200 baud.
2. Use the [←] and [→] and
UART Bits, as listed in Table 1-8 below.

3. 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 or PanaView software. See the
software User's Manual 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.
