Guralp Systems CMG-DCM build <10,000 - Manual (Page 14)

Acquisition Modules and Platinum Firmware Equipment Overview
Integrated instruments (seismometer or accelerometer, digitiser and EAM)
2.5 Ports
This section lists the ports (external connectors) found on Platinum systems.
Not all ports listed in this section are available on all devices. A typical NAM,
for example, only has power and Ethernet ports while the CMG-5TCDE
integrated instruments have Data, GPS, Ethernet, GPIO and USB.
Note: Refer to section 16.5 on page 273 for information on
connector pin-outs.
2.5.1 Ports A, B, C...
The 10-pin data input ports accept serial data from digitisers for processing by
an acquisition module. They can also be used for other functions, as listed in
the description of the Power/Data port, below.
2.5.2 SENSOR ports
CMG-DAS units have one or more 26-pin connectors for attaching analogue
instruments. They provide power and control signals to the instruments and
accept analogue data from the sensors.
The number of input connectors depends on the model of the digitiser.
2.5.3 Ethernet
The 6-pin Ethernet port is a 10BASE-T /100BASE-TX Ethernet connection,
referred to as eth0 within the user interface. The supplied cable supports
connection to a hub, switch or router. If direct connection to a PC or laptop is
required, an optional cross-over cable can be ordered.
