CMG-DCM Data Communications Module You can retrieve data from a DCM's disk at any time by removing it from the module and attaching it to a PC using a USB or FireWire cable. Swapping disks does not cause any risk to data. • A stand-alone DCM can also be supplied in a form factor suitable for mounting in a standard 19” rack. Such a DCM will normally come equipped with eight additional serial ports TTS0-7, and an optional State of Health (SOH) interface for monitoring or tamper evidencing. Up to four modules may be mounted side-by-side in a 19” rack. • An integrated or modular DCM may be combined with a digitizer and seismometer to produce a single unit capable of measuring seismic data, storing, and passing it on over a network: 6 Issue F
Operator's guide This form of DCM uses an integrated 26-pin connector to communicate, rather than having separate ports. A DCM in any of these forms may be supplied in the configuration most suitable to your requirements, depending on how you wish it to be connected to your network, and how its USB interface is to be used. The two sets of options are independent. • Using the 10BaseT Ethernet network option, you can connect the DCM to any TCP/IP network. • Alternatively, an internal PCMCIA modem may be supplied, through which you can use a dial-up or other communications link to connect to your home network. Most 56k analogue and ISDN-type modems are supported. • DCMs can also be supplied with internal satellite modems. • As a fourth option, an 802.11b Wi-Fi module may be installed. • If the USB client option is installed, you can connect the DCM's USB port to a computer and communicate with it as if it were on a private network. • If the USB host option is installed, you can connect the USB port to an additional peripheral, such as a camera or external hard disk. Whichever set of options you choose, you can use any free RS232 port to connect the DCM to a single computer for local monitoring and configuration, or through it to a wider network using PPP/SLIP.
