PARALLEL PORT: WaveBook/512A, /516, and /516A can be connected to a PC’s Parallel Port or to
an Ethernet. In regard to Parallel Port connection, use of an Enhanced Parallel Port (EPP) or an Extended
Capabilities Port (ECP) is recommended. Three WBK options, WBK20A, WBK21, and WBK23 are
available for use with PCs that do not have Enhanced Parallel Ports and are discussed on page 2-6. With
exception of the WBK20A, which has its own cable, when this type of connection is desired, a 2-foot
CA-35-2, or a 6-foot CA-35-6 communication cable is used to connect the WaveBook to the host PC.
In regard to Ethernet connection, the WaveBook can be connected to one of three Expansion Ports on a
WaveBook/516E or to one of three Expansion Ports on a WBK25 Ethernet Module.
EXPANSION CONTROL: The HD15 EXPANSION CONTROL connector provides a means of
connecting a control output signal [from the WaveBook/516E] to the 15HD EXPANSION CONTROL IN
connector of the first WBK expansion device in the system. Expansion Control signal lines can be daisy-
chained, as will be seen in upcoming system examples.
EXPANSION SIGNAL IN: This BNC connector provides a way for the WaveBook/516E to receive
return signals from the EXPANSION SIGNAL OUT BNC connector of the first WBK expansion device
in the system. Expansion Signal lines can be daisy-chained, as will be seen in upcoming system
examples.
To ensure EPP speeds are properly handled, it is important that WaveBook systems make
use of a 1284-compliant cable. Standard parallel cables will not work properly, primarily
due to a lack of shielding. Note that CA-35-12 (1 foot), CA-35-2 (2-foot), and
CA-35-6 (6 foot) cables are 1284-compliant.
Use of the CA-35-12 cable will result in less noise due to its shorter length.
