3. More than one panel connected to one switcher port.
Note
This method can only be used if the switcher is running system software V2.3 R2 or later.
Up to four Quartz panels can be connected to one switcher serial port to give independent
control of four Aux O/Ps whilst only using one switcher port. This allows other ports to be
used for other functions.
This method requires a RS-422 four way extender cable, a Master Diode Buffer unit and
three (max) Slave Diode Buffer units to be made, see below.
Extender cable
The extender cable is made from 9 way ribbon cable, 1 x 9 way “D”- type male connector
and (up to) 4 x 9 way “D”- type female connectors. The male connector goes at one end of
the ribbon cable.
9 pin male
"D"-type
9 pin female "D"-type connectors
The male 9 way “D”- type connects to the switcher port and the Quartz panels connect to
the female connectors via the Diode Buffers which are detailed below .
