HBM QuantumX CX22B - Connection of Quantumx Modules; Ground Connection and Grounding

Connections and displays
18 A3169-8.0 HBM: public CX22B / CX22B-W
Important
The data recorder hosts a small buffer battery (type
CR2032, lithium). This battery keeps date and time
during power interruptions. The battery shall only be
replaced by HBM service.
4.2 Ground connection and grounding
Lay the signal and data leads separately from current-
carrying power lines. Cable ducts made of sheet metal
with an internal partition are ideal.
If there are differences in potential in or to the connected
measurement system, you must install a potential equal
ization line (recommended value: highly flexible stranded
wire, line cross-section 10mm
2
).
4.3 Connection of QuantumX modules
The simplest way to connect measurement modules to
the CX22B‒W Data Recorder is via FireWire, or alterna
tively via Ethernet.
FireWire has the following advantages:
S Voltage supply, time synchronization, data communi
cation and real time in one cable and thus little effort
and low cost
S Every module has 2 FireWire connections, so flexible
topologies are possible: star, line or even hybrids with
an appropriate hub, also supplied with power via
FireWire.
Ethernet has the following advantages
