7.4.1.1 Setting up communication
After installation of communication equipment and before placing the communication system into operation, the user should note
the following:
— Verify RS-232 or RS485 interface modules and jumpers are installed or set correctly.
— Verify that radio cable or wiring is correctly installed at the radio.
— Verify field wiring terminations on the XFC
— Check flow computer identifier (ID). Log the ID for future reference.
— Log the access security code, baud rate, listen cycle, protocol and interface for future reference.
IMPORTANT NOTE: The following helpful hints aid the user after communication equipment has been installed
and setup:
If the comm port assigned to an annunciator, the XFC
Check baud rate, transmission and timing. The baud rate and timing settings can be changed within PCCU, in
Entry mode. Default settings are 1200 baud, listening time is 4 seconds, and communications interface is turned
off.
Minimum power required for operating remote communications is 11.9Vdc (default) or as set by user. Should the
power fall below this level, remote communications will be terminated.
Test remote communications using RS-232 troubleshooting cable (2011781-xxx). Use RS-232 to RS-485
communication Converter (1800255-xxx) in conjunction with RS-232 troubleshooting cable to test RS-485
remote communications.
7.4.2 Transceiver Supply Voltage Test
Using wiring information and guidelines supplied by transceiver manufacturer, verify that transceiver is receiving manufacturer's
suggested voltage. If unit is receiving sufficient voltage, continue to the 12V Communication Test.
IMPORTANT NOTE: If transceiver is not receiving sufficient voltage, investigate power supply issues. These
may involve wiring irregularities at either the AC charger/power supply system or the circuit board.
7.4.3 12V Communication Supply Voltage Test
Tools needed:
-Multi Meter (MM)
-Flat head tweeker screwdriver
To perform a 12V communication supply voltage test:
If transceiver features a SLEEP mode, or is continuously powered, proceed to step 6.
Connect the PC running PCCU32 to the flow computer with either an MMI cable (RS-232), a USB cable or an
Ethernet cable.
Open PCCU.
Select Entry mode from the toolbar
If transceiver does not feature a SLEEP mode and power is supplied through an optional relay.
a. Select applicable communication application from the tree.
b. Select the Advanced tab from the open pane.
c. Select the SwitchedV-Batt/Operate
d. Set to Enable
e. Click Send.
