e IR port — Connect an IR emitter to pins 3 (S, for signal) and 4 (G, for ground) of this
shared captive screw connector to enable infrared remote control of the output device
(see “Wiring for IR Control” for instructions on connecting an IR emitter to this port).
The PC1 provides enough current to power one IR emitter up to 4000 feet, or a
maximum of four emitters in parallel up to 100 feet each. To enable IR control, load an
Extron IR driver to the PC1 for the output device, using Global Configurator, the PC1
web pages, or IR Learning.
f Input contact closure port — Connect a contact closure device to pins 1 (IN, for input)
and 2 (_, for ground) of this shared captive screw connector to enable the PC1 to detect
a closed circuit between an input and ground and to trigger an event (see “Wiring the
Contact Input Port”).
For example, if a button were pressed or motion were detected by a sensor, the input
would short to ground, which would cause an event such as a bell ringing, a light
turning on, or an e-mail notification that an event has occurred.
g Output power receptacle — Connect the power cord from an output device to this
female 3-prong Edison (IPL T PC1) or IEC (IPL T PC1i) power output receptacle.
Connecting Cables
Connect cables to the rear panel connectors as outlined below.
1. Plug an IEC power cord into a wall outlet and into the 3-prong male power connector
on the PC1 rear panel. The green Power LED lights and remain lit.
2. Plug the Ethernet cable from the network into the LAN port on the rear panel. The
green Link LED on the connector lights.
3. Plug the power cord of the output device to be controlled into the output receptacle on
the PCI rear panel.
4. If desired, connect the output device to the RS-232 COM port.
5. If desired, connect an IR emitter to the IR port to control an output device.
6. If desired, connect a contact switch to the contact input port.
The following sections provide details on wiring the appropriate cables to the rear panel
connectors.
RS-232 Port Cabling
To connect an output device, such as a plasma display or projector, to the PC1 RS-232
connector, see the “Extron IP Link Device Interface Communication Sheet” for your
display device. This sheet contains information about your device, including connector pin
assignments and connection diagrams, and is available from the Extron website.
Accessing the Communication Sheet
To obtain the Communication Sheet for your output device:
1. On the Extron website (www.extron.com), click the Download tab.
2. On the Download Center page, click the Device Drivers button
(shown at right).
3. At the bottom of the Device Drivers page, select IPL T PC1 from the
drop-down menu.
4. On the next web page, select Serial from the Protocol Type drop-down menu to
display a list of the Extron serial drivers.
