Redistribution or publication of this documentby any means, is strictly prohibited.
OVERVIEW
This section describes the network and the individual nodes used in the Coach Command network. For
a definition of the terms used in a Coach Command
network, refer to the Glossary.
Once physical installation is complete, the system
must be configured using the Coach Command
Original Equipment Manufacturer (OEM) setup
menu. Network installation and configuration is covered in detail in the following sections.
NETWORK CONFIGURATION
Coach Command consists of a Touch Screen display networked with a series of nodes linking power
sources, appliances, and monitoring devices. The
network is made up of individual node boards that
are connected by twisted pair communications
cable for the transmission of network data. Network
power is transmitted over a second pair of wires.
The Coach Command power management system
includes six types of node boards, linking power
sources, appliances, and monitoring devices to the
Touch Screen display. The node types are:
• Master Node – Provides a network interface
for the Touch Screen display.
• Load Control Nodes – Up to seven nodes
provide load control and monitoring for items
such as air conditioners, hot water heater,
engine block heater, and appliances.
• Generator Node – Starts, stops, and communicates with Onan gensets. This node monitors generator voltage, frequency, RPM, engine temperature, operational hours, and
diagnostics.
• Tank Level Node – Provides tank level monitoring for the fresh water, grey water, black
water, and liquid propane gas tanks.
• Transfer Switch Node – Contains the network
power supply and provides the network with
coach voltages, currents, and battery voltage.
• Engine Interface (CAN) Node – Provides
monitoring of the coach engine.
Figure 2-1 shows an example of a Coach Command network configuration. Detailed information
on installing individual components is covered in
Sections 3 thru 10. Nodes can be installed in any
order on the network.
A Terminating Plug is required in the unused network connector on the first and last node in the network.

WIRING GUIDELINES
Communication over unshielded twisted pair (UTP)
could be distorted by external sources of electromagnetic interference (EMI), especially if the conductors are physically degraded in any way. To
avoid or minimize this interference, observe the following guidelines.*
CAUTION
can cause communication signal distortion,
which can cause network failure and unintended equipment operation. Read and follow
these wiring guidelines.
Observe all local wiring codes. Refer to the NEC

should be installed in such a way as to comply with
Electromagnetic interference (EMI)
Wiring Methods and Materials
LOAD CONTROL
NODE
the minimum separation of 5 inches (127 mm) from
AC power sources
In general, communications wiring should not be located in spaces that are shared with electrical panels, transformers, or other high voltage equipment.
Tension: All cabling should be free from tension at
both ends, as well as over the length of each run.
Twisted pairs: All terminations should be made in
such a way as to minimize the extent to which
each twisted pair is unraveled at the point of its
physical termination. Allow no more than 0.5 inch
(13 mm) of exposed untwisted pairs.
UTP cable bends: UTP cable bends, or radii,
should be no less than eight times the cable diameter.
* These guidelines are derived from “The Do’s and Don’ts of UTP Cabling” by Mark W. McElroy, in EC&M, June 1994.

Air Conditioners. For information on installing Load
Control Nodes used with Dometic Air Conditioners,
see page 6-3. For information on installing Load
Control Nodes used with Coleman Air Conditioners,
see page 6-5.
1. Choose a location that provides adequate
clearance for the communications cable (see
Figure 6-1). An acceptable location for mounting most Load Control Nodes is near the load it
is controlling.
2. Drill mounting holes as shown in Figure 6-1.
Make sure you do not drill into other electrical
components.
3. Adjust the dip switch setting on each Load Control Node so each controlled load has a unique
node address (see the Coach Command System Worksheet at the end of this manual). For
reference purposes, write the name of the load
on the Worksheet for each address being used.
4. Use appropriate fasteners to secure each
node. Do not overtighten screws.

Appendix B. Controlled Load Timing
Redistribution or publication of this documentby any means, is strictly prohibited.
This appendix covers controlled load timing issues
that apply when switching power sources. Timing
diagrams are shown in Figures B-4 thru B-8.
NOTE: See page 14-1 for a description of con-
trolled and non-controlled loads.
Whenever switching power sources, controlled
loads are temporarily disabled. Coach Command
turns off these loads until the new power source is
determined to be stable.
When Auto Gen is set to “ON” and the power source
switches from inverter to generator power, Dometic
and Coleman air conditioners have a time delay.
Shore Transfer Delay
is between 15–300 seconds.
The default setting is 30 seconds. To adjust the
shore transfer delay setting, see step 16 on page
11-5.
Generator Transfer Delay
is between 30–300 sec onds. The default setting is 60 seconds. (See Sec tion 11: System Configuration. To adjust the generator transfer delay setting, see step 18 on page 11-5.
Inverter to Shore Power
When the power source is set to inverter power,
non-controlled loads can function but all controlled
loads (except Dometic air conditioners) are disabled (see Figure B-1).
When the shore power connection is made, the
Power Source menu continues to show PowerSource: Inverter f or a n a dditional 3 0 seconds as t he
switch to shore power is made. The Power Source
menu then s hows Power S ource: S hore ( see Figure
12-2) and the loa d wit h the highest priority is e nabled

Dometic Air Conditioners
Unlike other controlled loads, the Dometic air conditioner can be enabled when the power source is set
to inverter power.
If Coach Command detects a demand signal from
the air conditioner while the power source is set to
inverter power and Auto Gen is set to “ON,” the generator automatically starts. When the generator
starts, the air conditioner is disabled and the Power
Source menu continues to show Power Source:Inverter for 60 seconds. When the switch to generator power is complete, the Power Source menu
then shows Power Source: Genset and the air
conditioner is enabled. After the air conditioner is
enabled, a time delay is included in the A/C controls,
resulting in an additional 1–3 minutes before the
thermostat A/C compressor starts.
Coleman Air Conditioners
If Coach Command detects a demand signal f rom a
Coleman air conditioner while the power source is
set to i nverter p ower a nd Auto Gen i s s et t o “ ON,” t he
