Humphree GPS 501 Instructions

GPS Antenna or NMEA2000 for GPS speed data input

Option 1: Connection to NMEA2000 Network

Connect to any GPS transmitting NMEA2000 Network according to the picture (right).
The Humphree Nmea2000 Drop Cable is pre fitted with the standardized Nmea2000 connector
and connects to any Nmea2000 T-Connector or Network Hub. T-Connectors and Network Hubs
are not supplied by Humphree.
Option 2: HUMPHREE GPS501 GPS-antenna
Part number: 020145
The GPS501 has a pre fitted Molex connector and connects directly to the GPS port (see picture).
(No settings required)
Part – Interface/GPS input
NMEA 2000 cable (GPS and rudder pos.)
GPS 501 (antenna with 14m cable)
Part – Interface/Monitoring, Remote Contr. Part no
Remote Key Switch (b)
Interface cable, 2.5m NMEA0183 (a)
EmpirBus Gateway (incl. s/w for Raymarine) Contact Humphree
Part – Interface/C-Turn or Steering Assist Part no
NMEA 2000 cable (GPS and rudder pos.)
Interface cable, 2.5m NMEA0183 (a)
Volvo Penta Gateway (c)
VPI - Volvo Penta Interface (d)
HCU 502 (with interface connection) (e)
Interface cable for MJP (WAGO system)
NMR 501 NMEA2000 Receiver (f)
Simrad RF25 rudder sensor (for 020433)
(a) The Interface cable connects to the Control Panel CP-502 and is used for rudder position sensor, GPS, monitoring and remote control.
An EXTBUS manual is available on request. This connection accepts both RS-232 and RS-422.
(b) The Remote Key Switch cable is connected to the Control Panel CP-502 and to the ignition to set the system in stand-by mode only
using the boat's ignition key.
(c) The Volvo Penta Gateway converts Volvo EVC signal to NMEA2000. If there is an NMEA2000 system on board, connect Humphree
NMEA2000 drop cable to the network and use the VP Gateway for receiving rudder position data.
(d) If a Volvo Penta powered boat doesn't have NMEA2000 network the VPI will provide an interface for the rudder position data to the
EXTBUS connector on the Humphree Control Panel CP-502.
(e) The HCU502 (and RCU522/542) control unit contains an interface cable for NMEA0183 (RS-422) rudder position data, analogue input
for 4-20mA and 0-5V.
(f) The NMR501 receiver for NMEA2000 is connected between the control unit HCU/RCU and the Simrad RF25 rudder sensor. This is a
stand-alone rudder position interface solution that connects to the standard BUS connector on any Humphree HCU/RCU unit.
