5.8. Digital Triax Transmission System

Another interesting alternative for signal transmission from camera head to CCU
offers the new digital triax adaptor, the CA-TX70. This adaptor is docked to the HXC-
D70 in exactly the same way as the CA-FB70 (via V-mount shoe) and can also be
compatibly be used in combination with the PMW-320/-350/-500 series of
camcorders.
The triax transmission system employed in the CA-TX70 is exactly the same as in the
HSC-100RT/-300RT series so that the HXCU-100 can serve as a compatible CCU.
Furthermore, it allows the integration of HXC-D70 cameras within an HSC-
environment.

The CA-TX70 triax adaptor employs a digital transmission technology. Thus, the
signal quality remains on a very high performance level, no matter which cable
extension is used. The maximum cable extension is 1,200m (using a 14.5mm triax
cable). As a standard connector, CA-TX70 employs FISHER connectors.
Other types of triax connectors are available as a chargeable option.
The HXCU-TX70 is a new digital triax CCU and is the successor to the HXCU-100
which is already discontinued.
In case the CA-TX70 is used in combination with a PMW-camcorder, the following
limitations apply:
 No TC output from HXCU-100.
 No 23.98P format is supported on the system.
 No REC trigger output from CCU (SDI output).
