5. The
FU-0003
Advanced Controller
supports an RS232/422 port, enabling the router to
be controlled from another piece of equipment. On the earlier FU-0001 this required a
further option CI-0001.
6. Crosspoint status is maintained while the unit is powered down.
With this option fitted it is possible to reconfigure the system using the Quartz WinSetup
Windows software package.
The option is currently supplied under the part number FU-0003.
THE Q-LINK SYSTEM
Q-link is used to interconnect the panels and router frames using a single coaxial cable,
making it very easy to install. A total run of over 500 metres of standard video cable can
be used between panels and the frames.
The Q-link is daisy-chained from one panel to the next and between router frames.
The
link must be terminated with 75
Ω
at both ends
, standard video practice. One or two
hex switches in each unit set the identity of each so that they are correctly addressed by
the control system. Up to 32 devices can be supported.
The Q1601 and Q1602 routers, when equipped with the
Advanced Controller
, and the
standard remote panels have a single Q-Link BNC connector so a T-piece is used to tap
off the Q-link signal into the units. In this way a unit can be removed from service without
the Q-link being interrupted, even momentarily.
SERIAL PORT
The serial port is used to connect to computers or other third party equipment. This
feature is available when the
Advanced Controller
option is fitted, processor FU-0003.
CASCADE MODE
When the
Advanced Controller
option is fitted several routers can be connected together
to appear like a much larger router, for instance a 76x1 router can be built from five 16x1
routers, or a 30x2 router can be built from two 16x2 routers. The outputs of the upstream
routers are cascaded into the downstream router, which acts as a master controller for
the system. In this application the
Advanced Controller
is installed in the downstream
router only.
These techniques are applicable to video, audio and audio-follow-video mixed routers.
The only limitation with this system is that the levels of the second destination of an ‘nx2’
router are always married.
The following table gives the maximum sizes that can be achieved by cascading a
number of Q1602 routers together.
