SCP 250 • Installation and Operation 2-9
c
IR signal pickup device — Like the IR signal pickup device on
the switcher, this receives commands from the IR 401 or IR 701
remote control and sends them to the switcher. Infrared signals
from other devices are not passed on through the switcher. The
IR remote must be within 50 feet (15.2 meters) of and pointed
directly at this device for best results.
N Switcher configuration must be done using the front panel
controls or RS-232 control. Configuration cannot be done
from the IR 401 or IR 701.
d
Room control buttons and LEDs — Room buttons control the
switcher’s Relay ports, which control “room” functions–items
such as room lighting, window coverings, and display
screens–via momentary or latching contact. The Room 1 button
can be used for both the System 5cr Plus and the System 7SC,
the Room 2 button is used only with the System 7SC.
These contacts may be used to control any equipment as long as
the contact specifications of a total of 24 V at 1 A are not exceed ed.
The Room buttons light while the room functions are active (on).
Refer to the System 5cr Plus User’s Manual and the System 7SC
User’s Manual for information on the room function/Relay ports).
e
Input selection buttons and LEDs — These buttons correspond
to the input selection buttons on the front of the switcher. See
page A-7 in this manual for an example of how the SCP 250’s
input selections buttons are assigned depending on the model of
switcher the SCP is connected to.
Testing/Troubleshooting
Before installing the control panel into the wall or furniture, test
the system to make sure that the connections are correct and the
SCP is working correctly.
1
. Connect the cables between the switcher and the SCP(s).
2 . Power on the switcher.
3 . Press the input selection buttons on the SCP, and watch the
LEDs on the switcher to see if the system switches to the
desired input(s).
N The connections between the SCP and the system switcher
can be tested even if input/output devices are not available.
• If the SCP’s input selection LED does not light, check
the captive screw connector wiring at both the switcher
and the SCP. If the conductor assignments are not
the same at both ends, the SCP will not turn on, and
circuits may be damaged if power is applied to the
wrong pole. Verify that the connectors are wired
