Installing the 6TD
The connectors for the FireWire and Ethernet options are both six-pin bayonet
plugs. If the labelling has become illegible for any reason, they can be
distinguished by noting that the FireWire connector lies to the East of the
instrument and the Ethernet connector to the North-East, as in the picture
below (which shows an early, unlabelled unit).
4.2.2 The Break-out box
In addition to the cable to the instrument, which is moulded into the case, the
breakout box provides
•
a six-pin bayonet socket for connecting the supplied GPS unit;
•
a ten-pin bayonet plug for connecting to a PC's serial interface or a
Güralp data module; and
•
a six-pin bayonet plug for connecting a 12 V power supply.
You may need to attach a suitable connector to the power cable provided.
The 6TD draws a nominal current of 75 mA from a 12 V supply when in use;
thus, using a 12 V, 25 Ah sealed heavy-duty lead-acid battery, you should
expect the instrument to operate for around a week without recharging.
