The system is limited to 10,000' of total network wire length. Please consult with dealer sup-
port for solutions designed for longer wire length requirements.
TROUBLESHOOTING NETWORK WIRING
From staples shorting conductors to miswired connectors, wiring problems occur. The options
below may help to diagnose common wiring and communication problems.
WORKING AT THE HUB
The red LED indicates power is OK. Green LEDs indicate network power is OK. Hubs are
split in half. The green LED on the right side indicates that the right half has good network
power. The left LED is for the left side network power.
First, look at the red LED. Is it bright? If not check the power.
Are the green LEDs dim?
If they are, chances are your +12 and GND wires are reversed.
Remove each cable one at a time until the LEDs light brightly.
Are the LEDs out?
Chances are the wires are shorted. Remove each cable one at a time until
the LEDs light brightly. When they do, you’ll know which cable has a problem.
GENERAL COMMUNICATION PROBLEMS
Communication problems are almost always the result of reversed network wires (A and B).
Use a multi-meter set to the 12 volt range and DC voltage. With the black probe on “A” and
the red probe on “B,” measure the voltages between “A” and “B.” The voltage should be
between 4 and 5 volts DC. If the voltages are negative, the +12 and GND are reversed some-
where between the Control 2 and the Hub.
CONTROL 2
The Sonance Navigator Network Control 2 processor is the brains of the system. All menus
displayed on the MagicPads and every action performed by the system originate at the
Control 2.
If the Control 2 is unable to communicate on the network or is otherwise disabled, the
MagicPad will display the last menu or it will display a blank screen.
When power is applied or upon reset, the Control 2’s power LED (visible from the front of the
Control 2 component) will illuminate and then wink dim (short flicker) once to indicate it is
operational. This is a strong indicator that the Control 2 is alive and well. If this power LED
winks dim once every few seconds, this may signal a problem with the unit, and you should
contact Sonance Technical Support.
