Connectors and Cables
To attach a module, connections must be made for power, expansion control, and expansion signals.
The following connectors and cables are used.
•
WaveBook POWER IN – connects to a 10 to 30 VDC source.
•
WaveBook POWER OUT – can be connected to the first module’s POWER IN.
•
WaveBook EXPANSION CONTROL – connects to the first module’s
EXPANSION CONTROL IN.
•
WaveBook EXPANSION SIGNAL IN – connects to the first module’s
EXPANSION SIGNAL OUT.
•
WBK POWER IN – connects to a 10 to 30 VDC source. When in a power daisy-chain,
POWER IN connects to the previous WaveBook or WBK module’s POWER OUT.
•
WBK module POWER OUT – can be connected to the next module’s POWER IN, providing the
5 amp current limit will not be exceeded. It may be necessary to use a supplemental power supply.
Power requirements and discussed in the following pages.
•
WBK module EXPANSION CONTROL OUT – connects to the next module’s
EXPANSION CONTROL IN.
•
WBK module EXPANSION SIGNAL IN – connects to the next module’s
EXPANSION SIGNAL OUT.
Prior to connecting your devices to power, calculate your system’s power requirements as
discussed in upcoming section of this chapter. Note that three examples of system setups
follow shortly.
Using Shielded BNC Connectors for CE Compliance
Certain Declarations of Conformity identify specific cables and connectors that must be used to
meet CE requirements. CE compliant BNC-equipped cards and modules have BNC connectors
that are insulated from high voltage sources, including electrostatic discharges (ESD). Such
voltages could enter the circuitry through the exposed conductive surface of a connector,
possibly resulting in damage to components.

Shielded BNC Connector (with O-Ring) and PVC Dust Cap
To meet CE requirements, PVC dust caps (p/n CN-96) must cover all unused BNC connectors.
When dust caps are not in place, special coaxial cables (with insulated end-connectors and
rubber O-rings) must be used. Note that part number 418-0800 includes two cables (with
shielded BNC connectors at each end), and four insulating O-rings.
Properly installed connectors and dust caps ensure the metallic surfaces of the connectors are
not exposed to undesirable electrical charges.
