Device Connection And Testing - Yacht Devices YDTC-13 User Manual

II. Device Connection and Testing
The Device requires no maintenance; calibration of the digital sensors has been
performed by the manufacturer. Therefore, you can set an offset from -10.0 to +10.0
(Celsius for Thermometer or hPa for Barometer) for the sensor readings to align
with readings from other ship equipment (see Section III).
When deciding where to install the Device, choose a dry mounting location.
Avoid places where the Device can be flooded with water, this can damage
it. The Thermometer sensor has a waterproof case made of stainless steel
and is not intended for permanent location in hostile environments such as sea
water. To prevent corrosion, when installing outdoors protect the sensor case with
the help of a coating of paint.
Read the model number on the Device case. If the model name has the T index
at the end (for example, YDBC-05NT), then the device has a built-in terminator
(with resistance of 120 Ohm) and must be connected to the bus instead of an existing
terminator. Different connectors for terminators (blue) and devices (white) are used
in the SeaTalk NG network, which eliminates the chance to err. In networks with
the NMEA 2000 Micro connectors (DeviceNet Micro, Garmin NMEA 2000), devices
are connected to the Female connector on the bus, while terminators are connected
to both Male and Female connectors.
The Device is directly connected to the bus without a drop cable. Before connecting
the Device, turn off the bus power supply. Refer to the manufacturer's documentation
if you have any questions regarding the use of connecting cables, terminators
and connectors:
