Reference Note: More power-related information can be obtained from the Power Connection
text, below, and from chapter 4, System Power & Assembly.
CA-129 Expansion Control Cables. Control messages are carried by CA-129 expansion-control
cables (HD-15, plug and socket connectors). The first expansion unit’s control input is driven from
the main unit’s control output. Control inputs of additional WBK10/10Hs are driven from the
preceding unit’s control output.
CA-150 Expansion Signal Cables. Expansion signals are carried by a CA-150-1 male BNC to
male BNC coaxial cable. Each WBK10/10H drives a common parallel analog bus that carries the
signals to the ADC in the WaveBook. Each WBK10/10H has input and output connectors for
daisy-chaining multiple units.
Power Connections
Reference Note: More power-related information can be obtained from chapter 4,
System Power & Assembly. CA-115 cables are discussed in preceding text.
10 to 30 VDC power can be supplied to a WBK10/10H unit through its POWER IN DIN5 connector in any
of the following ways.
• Separate power supplies. Each WBK10/10H can have its own, separate power supply. In other words,
the power set-up does not need to be dasiy-chained. Note that each WBK10/10H is shipped with a
power adapter.
• Single power supply. A single power supply can be used to power several WBK10/10H units.
An optional TR-40U power adapter can power several WBK10/10Hs when the units are daisy-chained
with CA-115 power cables (preceding figure). The number of WBK10/10Hs is limited to the amount
of power available and the amount of power used by option cards. As stated in the earlier caution, do
not daisy-chain the power for more than three WBK10/10H units.
• DBK30A Rechargeable Battery Module. The DBK30A can provide battery power for portable
applications via a CA-115 power cable. DBK30A is detailed in chapter 4,beginning on page 4-3.

• DBK34 Vehicle UPS Module. The DBK34 can provide back-up battery power as an uninterruptible
power supply (UPS) for portable applications via the CA-115 power cable. DBK34 is detailed in
chapter 4, beginning on page 4-6.

• CA-116 cable. A car battery can be used for power when connection is made via the optional CA-116
cable. The CA-116 is a 5-pin DIN to automotive cigarette lighter power cable.
