Remote Keypad
The Remote Keypad works with Murphy’s PV1000 and HV1000 model displays. It allows a
user to enter keypad commands whenever display installations are not conveniently located for
easy access.
The keypad contains the same navigation, menu and selection keys as found on the displays,
making it an easy transition to use. Fault lights, just like the ones found on the displays, are
located in the corners of the keypad. An audible alarm with a one-touch key for temporarily
disabling is provided, making it easy to recognize and address faults and alarms.

Installing an NMEA 2000® Network
Installing an NMEA 2000 consists of interconnecting NMEA 2000 electronic devices using
plug-and-play cables and connectors. The following pages provide a brief description of how
to setup a NMEA 2000 network using five basic steps:
1. Cable and Connector Network Basics
2. Installing Terminators
3. Supplying Power
4. Grounding the Network
5. Checking the Network
Please note that this installation guide contains a brief description of the basic concepts of
installing an NMEA 2000 network. You can learn more about installing NMEA 2000 networks
by contacting the National Marine Electronics Association (NMEA) at www.nmea.org and
consulting the following documents:
•
NMEA 2000 Standard for Serial-Data Networking of Marine Electronic Devices
•
NMEA Installation Standards
Cable and Connector Network Basics
Network Topology
The NMEA 2000 cable system uses a trunk (sometimes referred to as the backbone), drop
line, drop tee, and termination resistor.
The NMEA 2000 cable system includes five wires within a single waterproof cable: two signal
wires, power and ground wires, and a drain wire. The drain wire shields the signal, power, and
ground wires from external Radio Frequency Interference (RFI) and helps reduce RFI emission
from the cable.
Maximum Cable Distance
The cable distance between any two points in the cable system must not exceed 100 meters
(328 feet) for the Micro cable.
Maximum Drop Line Length
The maximum cable distance from any device on a branching drop line to the trunk link is 6
meters (20 feet).

Maximum Number of Devices
A maximum of 50 physical devices shall be connected to the network, and the disconnection of
any device shall not interrupt any other device on the network.
NMEA 2000 Cable
Micro cables contain five wires: One twisted pair (red and black) for 12VDC power, one twisted
pair (blue and white) for signal and a drain wire (bare).
Installing Terminators
Termination resistors are attached to each end of the trunk cable to reduce reflections of the
communication signals on the network. If you do not use termination resistors as described,
the network will not operate properly. Termination resistors are typically connected directly to
the last tee on the trunk line although they can be connected to a cordset extending from the
last tee on a trunk line.
Supplying Power
NMEA 2000 networks can use a power supply originating from a single-point connection to the
vessel’s 12 volt battery or one or more isolated power supplies distributed along the network,
but not a combination of battery and power supply connections. Over current protection
should be provided and should be sized in accordance with ABYC E-11, AC and DC
ELECTRICAL SYSTEMS ON BOATS, taking into consideration the smallest gauge of cable
being used for the backbone or drop cables. The NET-S wire is connected to the positive side
of the battery while NET-C is connected to the negative side of the battery.
Micro Power Capability
Micro cable is rated to 4 amps, however strategic placement of the power source could support
higher current. For example, 8 amps of power could be supplied to the middle of the trunk
where 4 amps is supplied to both sides of the power tap. It can handle large loads as long as
no more than 4 amps is drawn through any single segment of he trunk line. However, cable
resistance may limit your application to less than 4 amps.

Maximum Power Supply Voltage Drop
The NMEA 2000 network is designed to work properly as long as there is no more than a 1.5
volt difference in the power supply voltage between any two devices on the network.
Therefore, you should perform an estimate of the voltage drop across a network using the
following equation:
Voltage Drop = 0.1 x Network Loads x Network Length x Cable Resistance / 100
Where:
Network Loads is sum of Load Equivalent Numbers (LEN) for all
devices
Network Length is in meters
Cable resistance is in ohms/100 meters
Ground the Network
The NMEA 2000 network should be grounded at ONE location. Grounding at more than one
location may produce ground loops, which can cause problems with communications on the
network. In addition to the ground wire, connect the drain or SHEILD wire at the supply ground
location and NO other place.
Checking Your Network
Verify that the network has been correctly designed and installed by reviewing the following
checklist:
•
Number of devices does not exceed 50
•
Maximum Micro cable distance between any two devices does not exceed 100 meters
(328 feet)
•
No drop should be greater than 6 meters (20 feet)
•
Termination resistors are installed on both ends of the trunk
•
The network is grounded at a single location
•
The SHIELD wire is connected to a single point, the supply ground
