Multi-SPU installation
If there is more than one P4 system in your NMEA 2000 network, you need to specify which P4 system the
Remote is going to join.
Each component in a P4 system has a configuration setting AP group. This group number is an integral in
the range of 0 to 13. At factory default all P4 components have an AP group number 2.
Each SPU installed in the same network must be assigned a unique AP group value. Refer to P4
installation manual for how to set AP group for an SPU.
When a Remote joins a P4 system, it will automatically pick up a SPU with the same AP group number. To
move the Remote from one group to another, place the Remote in repeater mode, and double click CMD
button. Change the AP group number in the menu. After the group number has changed, the Remote will
automatically delete SPU information it has already pick up, and scan the network all over again.
Care & Maintenance
There are no user-serviceable parts or adjustments inside the Remote enclosure. Should the unit become
damaged in any way, return it to an authorized ComNav Dealer.
A few precautions will keep the unit in prime condition and result in years of trouble-free service:
• The Remote housing does not require any special maintenance other than an occasional cleaning.
• Avoid exposing the housing to solvents, acids, and bases as some of these may weaken the casing.
• Although the Remotes are watertight, it is not designed for submersion under water.
