AP info
This item shows you the current P4 SPU you are linked to. In figure below the NMEA 2000
address of the SPU is 34. If the SPU is not online, you will see a blank address.
You can remove the linked SPU by press LITE button. The P4 remote will make a new scan
to the CAN bus to find a new SPU. If you have replaced your SPU, this is how you setup a
new link.
However, if you are to installed a second P4 system, and you want to connect the P4 remote
to a specific SPU, you must first POWER OFF the SPU you don’t want before you press LITE
to link the SPU you want.
Numbers behind P4SPU (“—030”) are the last 3 digits of the serial number of the P4 SPU.

Off mode or Sleep mode
P4 remote is powered by the NMEA 2000 bus it connects to. In order to synchronize with the
SPU and other control station in the network, P4 remotes do not have a power off state as
long as the network power presents.
However you can “turn off” a P4 remote locally if it is a repeater. In “turn off” state, the
backlight of P4 remote will be off. No display is seen, and the device will consume minimum
power.
To turn off a P4 remote locally, press and hold the STBY button for over 3 seconds. A
message will be shown before the system goes to sleep.
To wake up a P4 remote locally, press and hold the STBY button until the screen lights up.
If the SPU the remote linked goes to sleep, the P4 remote will automatically go to sleep
mode. When the SPU wakes up, it will also wake up the P4 remotes.
