(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
