2.2.1.5 CXF16 and CXF32 Asynchronous Controllers
The CXFI6 and CXF32 are asynchronous multiplexers that provide full-
duplex serial
data channels on Q-bus systems. The CXFI6 supports one
I6-line port. The CXF32 supports two I6-line ports.
The CXFI6 and CXF32 options consist of one module (installed in the
system), and either one fiber-optic cable and one terminal concentrator
(CXFI6),
or two fiber-optic cables and two terminal concentrators (CXF32).
The fiber-optic cable(s) connect the module in the system to the terminal
concentrator. The terminal concentrator plugs directly into a wall outlet.
