１MSENS-GY features and specifications
１-１Features
The main advantage of MSENS-GY is to measure motion about all directions, and it is
possible to output angle value about gyro. It provides best solution about any
application by Microprocessor. The user settings can be stored in internal memory of
sensor. (direction, the analog output range, the sensor ID, specify the initial value, etc.) In
addition, because the sensor RS-485 communication can be connected to more than
1Km, a line can be connected to Maximum 254 sensors. Core sensor shield to prevent
penetration through the strong noise, motors, etc. can be used in strong noise
environment. Sensors have been molded silicone inside can be used in inclement weather

３ Wiring
MSESE-GY for a six-stranded shielded cable is used. Supply voltage 2-line, RS-485
2-line, mA output consists of a line. RS-485 and the unused line of mA output
does not touch the other by cutting the cable must be insulated. When using RS-
485 distance is longer than 50M 120 Ohm termination is recommended. In
addition, if multiple sensors connected in parallel to use in the termination
resistors.
３-１RS-485 Wiring.
RS-485 communications can be read sensor value when the one or more
sensors can be connected in parallel to a line. However, caution this time, each
sensor's ID to be different, continuous data read (# READ) instruction, such as ID
and to answer all the sensors, regardless of instruction should not be used. And
when you use multiple sensors to allow sufficient power supply wiring should be
designed.
