5.4.3 Transceiver supply voltage test

Using the wiring information and guidelines supplied by the transceiver's
manufacturer, verify that the transceiver is receiving the manufacturer's suggested
voltage. If the unit is receiving sufficient voltage, continue to the 6270 OEU Wiring
Voltage Test.

5.4.4 6270 OEU supply voltage test

If the transceiver does not feature a Sleep mode and power is supplied through an
optional relay, begin with step 1.
If the transceiver features a Sleep mode or is continuously powered, begin with
Step 2.

Check the G4 EX identifier (ID). Log the ID for future reference.
Log G4 EX access security code, baud rate, listen cycle, protocol and
interface for future reference.
The following helpful hints will aid the user after the
communication equipment has been installed and set up:
- When the communication equipment is powered/switched
- Check the baud rate of the G4 EX transmission and Listen
- Minimum power required for operating remote
- Test remote communications using the RS-232
If the transceiver is not receiving sufficient voltage,
investigate the power supply issues. These may involve
wiring irregularities at either the charger regulator,
termination board, terminal strip or at the power relay if using
relay for switching power to the radio.
Wire color/origination inside the 6270 enclosure should
comply with WI drawings. For the purposes of these
instructions, wire color name and designation should
coincide with the Totalflow drawings. The user may need to
adapt, as appropriate, for their individual installation.

time settings. The baud rate and time settings can
be changed when PCCU32 is in Entry mode. Default
settings are 1200 baud, the listening time is 4
seconds and the communications interface is turned
off.
communications is 11.9 VDC (default) or as set by
the user. Should the power fall below this level,
remote communications will be terminated.
troubleshooting cable. Use the RS-232 to RS-485
communication converter in conjunction with the RS-
232 troubleshooting cable to test RS-485 remote
communications.
