5.4.7 RS-232 communication
The following test procedure is directed from Figure 5
–7 and will assist the user in
what may be the possible cause for an indicated error message.
With the exception of the field wiring directly on the G4 EX termination board, all
other wiring is located inside the 6270 OEU enclosure; therefore, two separate
procedures are required for testing.
5.4.8 RS-232 termination board test
Before performing the voltage test on the termination board located inside the rear
end cap, verify that the wiring is correct (see Table 5

When troubleshooting RS-232 mode, verify the settings of
COMM 1 SW 1 and COMM 2 SW2 on the termination board
are configured properly (see Figure 5
5.4.8.1
Step-by-step instructions
Voltage on the following steps may be hard to see using a
Digital Multi-meter (DMM). If available, an oscilloscope will
provide a more accurate reading. To verify, the WinCCU
software must be continuously polling the meter
Generally speaking, these tests performed on the
termination board will only verify incorrect or damaged
wiring. If all previous testing passed and all wiring, jumpers
and terminations have been verified correct, the board will
need to be replaced. Contact Totalflow Customer Service.
