The Daisy-Chain Concept
TR-40U Connects to power. Each device is being powered by its own TR-40U.
The CA-242 [or CA-242-7] is a Ethernet patch cable that connects the ZonicBook/618E
to a PC’s Ethernet port or to a network Ethernet hub.
The CA-129 is a 15 pin connector cable used for Expansion Control.
The CA-150 is a BNC-to-BNC cable used to carry Expansion Signals. The signals go to
the ZonicBook/618E’s Analog-to-Digital Converter (ADC).

How Analog Input Channel Numbers are Determined
The analog input channel numbers are determined by the order of connection
among the ZonicBook/618E and attached WBK18 modules.
• Channels 1 through 8 are the ZonicBook/618’s main channels.
• Channels 9 through 16 are located on the first expansion WBK18 unit,
i.e., the module connected directly to the ZonicBook/618E.
• For each additional WBK18 channel numbers are added in groups of 8, as
indicated in the table at the right.
Note: No more than six WBK18 Expansion Modules can be attached to one
ZoniBook/618E.
