Room control through the System 7SC
Once room control devices have been connected to
the relays on the System 7SC, the user has a choice of
several ways to control equipment in the room. The
most obvious method is to use the front panel on the
System 7SC, but this may not be convenient. As an
alternative, an IR remote control (which is supplied with
the switcher) can be used to control switcher functions,
the projector, and room devices.
Figure 2 shows the
front panel of the System 7SC and the dedicated room
control buttons.
Another option is to use one of Extron’s SCP control
pads. These can be installed anywhere in the room
(such as desktops or walls) and allow the user to control
the projector, switching, and room functions.
Figure 3
shows the SCP 250 control pad.
The SCP control pads can be obtained in either
wall/desk plate form (such at the SCP 250 shown
above) or as an AAP plate, which can be mounted in
wall plates with AAP openings. Placing the SCP control
pads around a room allows room equipment, the
projector, and the switcher to be conveniently
controlled from various locations.
Figure 4 shows the
overall system.
If a third party control system is already in place, the
System 7SC can be controlled via RS-232. The relay
functions can also be controlled through RS-232 This
in turn allows the third party control system to control
room functions.
