Using Custom Built cables
When you need a cable length not available in a standard size.
When a cable must be routed through a conduit that is not large enough for a standard cable’s
connector to fit through.
Building Custom Length I/O Bus Expansion Cables
This section provides details needed to create custom length I/O Bus Expansion cables.
Two Types of Custom Built Cables
The two types are:
Point-to-Point - these have a single male connector on one end and a single female connector
on the other end. These are usually used with the IC693CBL300 which supplies the Wye
connection. This combination saves time since a point-to-point cable can be built much faster
than a Wye cable.
Wye - these have a single male connector on one end and two connectors (one male and one
female) on the other end.
Components Needed to Build Custom Length I/O Bus Expansion Cables
Note: the special two-headed Wye connector used on the standard Wye cables
is not available as a separate component.
