Connecting The Water Temperature Sensor (Thermistor Type) ¥¥¥¥¥¥¥¥¥¥¥¥¥¥ 2 - JRC JFV-130HP Series Installation Manual

2.8 Connecting the Water Temperature Sensor (Thermistor type)
Connecting the optional water temperature sensor allows the JFV-130HP to display wa-
ter temperature.
Thermistor type water temperature sensor alone is connectable. For connecting NMEA
type sensors (available from Murayama Ltd. and others), refer to Section 2.9.3.
In order to have the display, the water temperature value display position must be
changed from the upper left side to the lower right side.
And, attach the clamp filter and fix it by turning the water temperature sensor cable on it
once.
(1) Connecting CHG-97 (JRC standard)
CHG-97 is a through hull type water temperature sensor.
Insert the sensor connector to J903.
In this case, display of boat speed data provided by the paddle sensor is disabled.
See the external view in Figure 2.2.
(2) Connecting OP-102 (from Suzuki Fish Finder Ltd.)
OP-102 is a water temperature sensor designed to be mounted on the Kingston valve.
Its impedance is not identical with that of the connector, so modification is needed
prior to its mounting.
For the modification, see Figure 2.1.
And, add 10 kΩ resistor RN26C2C10kohmF (stock code: 5REAE00639).
(3) Connecting T80
T80 is a compact water temperature sensor mounted in the hull or on a transducer.
Its current connector must be replaced before use.
For the modification, see Figure 2.1.
Replace the current connector with NS1008 (stock code: 5JWDR00007).
