CMG-3ESPCD Digital Broadband Seismometer Installing the 3ESPCD
•
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.
•
Avoid moving the instrument whilst the masses are unlocked. The
3ESPCD is designed to tolerate a certain amount of motion with the
sensor masses unlocked, e.g. over short distances carried by hand. For
example, if the remote locking procedure fails, removing the
instrument for diagnostics is unlikely to damage it. However, you
should always lock the sensor masses before shipping or transporting
the sensor over longer distances.
3.1.4 Connections
The instrument has the following connectors:
•
The DATA OUT connector outputs RS232 data to your PC or data
module, and also provides power to the instrument.
•
The GPS connector is intended for connection to a Güralp GPS module.
•
The FIREWIRE connector can be attached to any IEEE.1394 (FireWire)
hard disk or data storage unit using the cable provided.
3.1.5 FireWire
The digitiser has an IEEE.1394 (“FireWire”) port, which you can use to
download data onto a compatible hard disk.
Before you can use the disk, you will need to erase/format it. The digitiser
saves data on the hard disk in raw mode, so you cannot use a PC's standard
software to reset the disk.
To erase/format a FireWire disk for use with the digitiser:
1. Power up the digitiser, and connect it to your computer's serial port.
2. Open its terminal console. To do this using Güralp Systems' Scream!
software, right-click on the digitiser's icon (once it appears) and select
Terminal.... From a Güralp EAM, issue the command
data-terminal
and select the appropriate data source from the menu
3. Issue the command DISKMENU. You will see the message
Plug in FireWire cable
4. Plug in your disk. The digitiser will display information about the disk
as soon as it is detected.
