UBP (Universal Beltpack) Initialization Troubleshooting Table

Unpredictable beltpack and system operation can occur if the BP4000/5000 is configured to a mode that
does not match the operational mode of the network power supply and/or the associated master station.

IMPORTANT:
powered network. Mode sensing is not reliable when done in conjunction with
enabling power to an entire network using a switched power supply or master
station. The voltage ramping characteristics of a switched power supply during
power up do not allow the UBP to reliably determine the mode of the network
In a Clear-Com system setup, the first beltpack MUST be manually configured to
IMPORTANT:
enable the mode-sensing setup feature for subsequent beltpacks.
Issue
UBP is configured to
power-on to a specific channel and no
power is present
EXAMPLE:
RTS UBP is configured for power
•
on CH 1 and is plugged into a
network with power only on CH 2.
Clear-Com UBP is plugged into an
•
RTS network with power only on
CH2.
RTS UBP is configured for power
•
on CH2 and then is plugged into a
Clear-Com network or RTS network
set for power on CH1.
Audiocom UBP is plugged into a
•
Clear-Com network or RTS network
which has power on only one
channel.
UBP is designed to operate on networks
with valid line voltages of 18Vdc–
33Vdc. Unit is detecting voltages
outside of the expected range.
