Extron Electronics IPL T CR48 - Manual (Page 13)

Ethernet/LAN
b
LAN port — Plug an RJ-45 jack into this socket to connect the unit to
a computer network. Use a straight-through cable to connect to a
switch, hub, or router, and a crossover cable to connect directly to a PC.
Activity LED — A blinking yellow LED indicates LAN activity.
Link LED — A green LED lights to indicate a good LAN connection.
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable. A cable wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

Connections
c
Contact closure — Four inputs permit connection of switches and sensors to provide
input (trigger events) to the system.
d
Relay ports — Eight relay ports provide contact closure activation of relays for power,
screen projector lift control, drapes, and so on, when trigger events occur.
Indentification
e
MAC address — The unique hardware ID number (MAC address) of the unit (for
example, 00-05-A6-00-00-01)
Operation
Connect power cords and turn on the output devices (such as projector lifts, screen lifts, and
lights), input (trigger) devices (such as motion detectors, and alarms), controller, and network
devices (PC, laptop, and network equipment).
Check indicator LEDs on the PC or laptop, on the unit, on the network hub or router, and so
on, to ensure that all devices are plugged in and communicating. The IPL T CR48 is ready to
be configured (see the
Connection and Configuration section).
See Troubleshooting in the “Connection and Configuration” section for information if
connection or communication problems occur. If the troubleshooting tips do not help, check
with your local network administrator, or call the Extron S3 Sales and Technical Support
Hotline.
