18 Initial Setup and Configuration Universal Beltpack
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:
Mode-sensing setup can only be done using a hot plug of the UBP into an already
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
IMPORTANT:
In a Clear-Com system setup, the first beltpack MUST be manually configured to
enable the mode-sensing setup feature for subsequent beltpacks.
Behavior After Power-On Issue Resolution
•
TALK and CALL buttons
do not work and
associated LEDS do not
light.
•
Unit cannot access
PROGRAM MENU.
•
While connected to the
network, the beltpack
may produce repeating
sets of audible clicks as
initialization attempts are
made.
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.
Perform mode-sensing set-
up to restore unit to proper
operation, see “Mode-
Sensing Setup” on page 19.
All LEDs on UBP flash
constant UBP is designed to operate on networks
with valid line voltages of 18Vdc–
33Vdc. Unit is detecting voltages
outside of the expected range.
•
Validate network for
proper operating line
voltages.
•
Perform mode-sensing
set-up to restore unit to
proper operation, see
“Mode-Sensing Setup”
on page 19.
