User’s manual

Before using

Applications

1. This equipment is 3-axis, use the following information to be checked.

2. Check used to test the power. 10 ~ 30Vdc voltage is used. In noisy

environments must be connected to the ground.

3. Connect the correct cable to determine the index, please. Incorrect

connection may result in damage of the equipment.

4. 1 year warranty on this product.

Navigation of vehicle, Speed detecting.

1.

2. Earthquake Detection, Tilt measurement

3. Motion Control

4. Virtual Reality System Application

5. Measurement of the bridge safety inspection

6. vibration of Facilities, equipment and structures detection

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.

3-axis accelerometer & 3-axis gyro sensor

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.
