CMG-3TD

Digital sensor

Installation

Check that you have all components and cables:

•CMG-3TD digital weak motion seismometer;

•GPS receiver;

•Brown GPS sensor cable;

•Blue/grey combined sensor PC and power cables;

•Sensor calibration data booklet.

You will need a Windows or Linux PC with an RS232

serial (COM) port and a 12–24 V DC power supply.

↔

Choose suitable sites to install the sensor and the GPS

receiver. The sensor should be mounted:

•at or, ideally, below ground level;

•in contact with bedrock or, if that is not possible, on

a hard granite or concrete pier;

•in an environment with constant temperature;

•shielded from air currents (e.g. in a polystyrene box);

•away from electrical cables and appliances.

The GPS should be placed:

•within 15 metres of the sensor;

•with a wide view of the sky and a low horizon.

Connect the various components together:

•Connect the brown cable from the GPS receiver to

the GPS connector on the sensor;

•Connect the 9-pin ‘D’ connector on the blue cable to

your PC’s serial (COM) connector;

•Connect the free, stripped end of the grey cable to

the power supply. Connect the black wire to the

negative (–) terminal and the red wire to the positive

(+) terminal;

•The blue and grey cables are joined together at a 10-

pin mil-spec socket. Attach this to the DATA

connector on the sensor. Do this step last.
