Chapter 3: MOTOMESH Duo Hardware
Reset Plug Usage Information
An optional Red Hardware Reset Plug is used to reset a MOTOMESH Duo device back to its
factory default configuration. See procedure below.
Procedure 3-2 Reset Plug Usage Information
1
Power off the MOTOMESH Duo device.
2
Connect the Reset Plug to the Select port.
3
The Hardware Reset Plug must be inserted for more than 4 seconds, and then removed.
4
Power cycle the MOTOMESH Duo device.
Connecting Power
MOTOMESH Duo devices can be ordered as AC or DC current devices.
• AC Input requirements – 90 to 264 VAC
• DC Input Requirements – 10 to 18 VDC
Before power is attached to a MOTOMESH Duo device make sure that the electrical circuit your are
connecting to is not energized. Verify that power has been removed from the correct circuit by using a
voltage meter.
If the MOTOMESH Duo device is being installed on a pole or structure that is not properly grounded an
external grounding wire must be attached via the ground lug on the MOTOMESH Duo device. This
ground wire must be attached to a bonded pipe or ground rod.
Grounding Considerations
In order for a grounding system to be effective, a low impedance path to earth ground must
be present. The grounding system must have conductors of sufficient size to withstand the
high fault currents that must be shunted along this path. The lower the impedance the
grounding system displays, the better its capability to perform its task. The impedance
requirement for a communications site is determined by the classification of the site. Sites are
broken down into 2 categories: Type A-Light Duty and Type B-Light Industrial/Commercial.
Type A-Light Duty sites have impedance requirements of 25 ohms or less to ground whereas
Type B- Light Industrial/Commercial sites have impedance requirements of less than 5 ohms
to ground. MOTOMESH networks fall into the Type B-Light Industrial/Commercial category,
and therefore must be treated with greater considerations as far as grounding requirements
are concerned.
