CMG-40T
2 First encounters
2.1 Handling notes
Although the 40T has a rugged design, it is still a sensitive instrument, and can
be damaged if mishandled. If you are at all unsure about the handling or
installation of the device, you should contact Güralp Systems for assistance.
• Avoid bumping or jolting the sensor when handling or unpacking.
• Do not kink or walk on the data cable (especially on rough surfaces such
as gravel), nor allow it to bear the weight of the sensor.
• Do not connect the instrument to power sources except where instructed.
• Do not ground any of the signal lines from the sensor.
All parts of the 40T are waterproof.
2.2 Connections
The instrument has an integrated cable ending in a 26-pin mil-spec socket
which carries both power and output signals. This is suitable for connecting
directly to a Güralp digitizer.
The breakout box, if ordered, provides individual signal and power connectors,
or you can make up your own cable if you prefer.
The breakout box
If you are using a Güralp breakout box, it should be attached to the sensor
through its SENSOR connector. Connectors are also provided at the CONTROL
and RECORDER outputs, for attaching to a handheld control unit or a Güralp
digitizer. If you have ordered a 40T with optional high gain outputs, you will
need to make up a suitable cable to expose these outputs.
