Table 1 - Fluid Flow Sensor Connections
Please refer to Figure 6 for connecting the FFM100 to a M1RSP-2R-E8, M2RSP-2R-E8, or
M4ARP-2-E8 fluid flow sensor. This figure shows the connection of the fluid flow sensor to
channel 0. Connections to other channels are similar.

2.5.2 NMEA 2000
®
Connection
The NMEA 2000
®
connector can be found on the side of the enclosure. The NMEA 2000
®
connector is a round five pin male connector (see Figure 7). You connect the FFM100 to an
NMEA 2000
®
network using a Maretron NMEA 2000
®
cable (or an NMEA 2000
®
compatible
cable) by connecting the female end of the cable to the FFM100 (note the key on the male
connector and keyway on the female connector). Be sure the cable is connected securely and
that the collar on the cable connector is tightened firmly. Connect the other end of the cable
(male) to the NMEA 2000
®
network in the same manner. The FFM100 is designed such that
you can plug or unplug it from an NMEA 2000
®
network while the power to the network is
