R.M Young 32500 ELECTRONIC COMPASS WITH SERIAL INTERFACE

The Model 32500 ELECTRONIC COMPASS measures magnetic heading, wind speed and direction signals from YOUNG sensors, and signals from four general purpose voltage inputs. Wind direction input may be combined with the direction input to obtain true direction. Voltage inputs may be used with YOUNG temperature and humidity, barometric pressure, precipitation, or other sensors. These input signals are converted into scaled values and placed on a serial string, which is output at up to 15 hertz.

Measurements are available in several formats in either full duplex RS-232 or half-duplex RS-485 signals. Both continuous and polled serial outputs are available. When polled, up to 16 units can be networked together. For marine applications the 32500 produces standard NMEA serial output sentences. Calibrated voltage outputs for wind speed and direction are also provided when the 32500 is connected to a YOUNG wind sensor
