Electronics International FP-5L - Manual (Page 9)

Any excess wires can be rolled up and tie wrapped under the instrument panel. Tie wrap these wires so they
do not obstruct the freedom of travel of any controls. If you decide to cut these wires to a specific length, strip
each wire and double the wires over. An extra set of connectors is provided in the kit. Double crimp each con-
nector. Doubling the wires over and a good crimp are critical.
Note: A dab or grease or two drops of oil on the red connectors will protect them for many years.
9. Install A Functional Module:
If the Aux channel on the FP-5 is to be used to monitor a function (EGT, TIT, Fuel Pressure, Oil Pressure,
etc.) an appropriate Functional Module must be installed. A Functional Module is a small box with circuitry used
to convert Temperature, Pressure, Voltage, Amps, etc. to an appropriate signal the FP-5 can display on the Aux
channel. These modules are small and light and are tie wrapped under the instrument panel. They come with a
Circular Connector so they may be installed and removed easily.
Install any Functional Modules at this time. Installation Instructions for the various Functional Modules
come with the modules.
10. (FP-5L Only) Connect the RS-232/422 Input Lines:
Connecting the FP-5L Input Lines to a compatible GPS unit allows the FP-5L to display Fuel to Destination,
Fuel Reserve, Nautical Miles per Gallon and Statute Miles per Gallon information. The FP-5L has three GPS
Receive Formats: 1. "In1" for all panel mount GPS units (9600 baud); 2. "In2" for Northstar (1200 baud); 3.
"In3" for hand held GPS units (NEMA at 4800 baud). The protocol is 1 start bit, 8 data bits and 1 stop bit and
the RS-232 update time of the GPS unit should be 1 to 2 seconds. The GPS unit may require some setup. You
may want to contact a knowledgeable instrument shop or the GPS factory to help with the hookup and setup of
the GPS unit. See the "Power-Up Programmable Settings" section in the FP-5(L) Operating Instructions to
configure the FP-5L RS-232 input.
