Note: The user may not see the " " symbol flashing where baud rates
are set higher than 2400. The user may need to set the baud
rate to 1200 to see if the port is active and then set it back to the
preferred baud rate.
The protocol needs to be selected in PCCU32 Entry mode.
o
Inadequate DC voltage (9 V minimum) or as specified by the
o
user in the Station Setup within PCCU32 Entry mode.
•
Ensure that the base radio is working for other locations.
•
Verify the Station ID and the Device ID matches with WinCCU
and is the only device with that ID.
•
Verify baud rate, stop bits, security code and listen cycle time are
the same as in WinCCU.
•
Verify that WinCCU is using packet protocol. The µFLO
supports DB2 protocol only.
•
Verify wiring from the µFLO
from the radio to the antenna.
Note: To check for wiring shorts or opens with two or more wire
connections, use a multimeter set on continuity (resistance).
Check two wires at a time from one device to another. If the
black and white wires are to be tested, disconnect both at both
ends. Place one probe on black and the other on white. The
meter should read OL or OFL (over range) if there are no shorts.
Jumper the two wires at the other end. The meter should read a
low resistance if there are no opens. This method requires only
one end of the wiring to be tested, no matter how far the devices
are apart.
If a radio is used, verify the directional antenna with the correct
frequency range is pointed towards the base +6°. The antenna should be
mounted vertically with the vanes perpendicular to the ground. Verify that
the radio is good with the same frequencies used to the base radio and
the remote.
•
If a modem is used, verify the dial tone online at the telephone
company's termination box by checking Tip and Ring. Check the
wiring from the phone company's box to the dial-up modem. If
cellular, check for proper Tip and Ring voltage availability.
Ensure the phone number is correct in the µFLO
Note: The telephone company uses a 48 Volt power supply. As a
result, the typical on-hook voltage between the Tip and Ring
wires should be something less than 48 Volts. Measuring a
different way, Tip to ground is approximately 0 Volts. Ring to
ground is approximately -48 Volts.
In the off-hook condition, Tip to ground is approximately -20
Volts, while Ring to ground is approximately -28 Volts or
approximately 8 Volts between Tip and Ring.
