Note: An optional CA-116 power cable is available. The CA-116 permits the system to be plugged into

a vehicle cigarette lighter, allowing use of the vehicle’s battery as a power supply for the

WaveBook device.

Calculate system amp load prior to creating a system daisy-chain. Although WaveBook

device connectors and CA-115 and CA-116 power cables have 5 amp limits, TR-40Us are

limited to 2.2 amps. Tables for determining amp load are provided in the following section,

Calculating the System Power Requirement.

CA-129 Expansion Control Cables. Control messages are carried by CA-129 expansion-control

cables with 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 WBK modules 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 WBK module drives a common analog bus that carries the signals

to WaveBook’s Analog-to-Digital Converter (ADC). Each WBK module has EXPANSION

SIGNAL IN and EXPANSION SIGNAL OUT connectors for daisy-chaining multiple units.

CA-177 Strain Gage Cables. CA-177 is an optional set of eight strain-gage cables intended for

use with the eight channels of WBK16. Discussions of the CA-177 strain-gage cable and bridge

applications are contained in the WBK16 document module.

CA-217 Digital Expansion Cables. These 8-inch cables are used for connecting one or more

WBK17s to a WaveBook/512A, /516, /516A, or /516E. The CA-217 cable has a DB25M

connector for Digital Expansion Out and a HD26M connector for Digital Expansion In. (See the

following page, second figure).

CA-242 and CA-242-7 Ethernet Patch Cables. CA-242 is a 1.5 foot cable that can be used to

connect a WaveBook/516E to an Ethernet port on a PC or network. CA-242-7 is a 7-foot cable

that can be used for the same purpose.

CA-74-1 and CA-74-5 SYNC Cables. 1-foot and 5-foot cables [respectively] used to synchronize

up to four “A” and/or “E” Series devices. The total combined SYNC cable length is not to

exceed 15 feet (4.57 m).
