E
LAN port — Plug an Ethernet cable into this RJ-45 jack to connect the unit
to a computer network. Ethernet control allows you to configure and control the DSC
from a remote location using SIS commands, the PCS software, or the embedded
Web pages. When connected to an Ethernet LAN, the DSC can be accessed from
a computer running a standard Internet browser. Use a patch or crossover cable to
connect the DSC to a switch, router, or computer.
The LAN connector contains two LEDs (see the illustration at right):
•
Act LED — This amber LED blinks to indicate LAN signal activity.
•
Link LED — This green LED lights steadily to indicate a 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 that is wired the same at both ends
is called a "straight-through" cable, because
no pin or pair assignments are swapped.

Reset LED — This green LED remains lit while the DSC has power. While the
Reset
button (
H
) is being pressed and held, this LED blinks every 3 seconds to indicate the
level of reset that will be initiated if the button is released at that point (see Resetting
on page 41 for more information).
H
Reset button — This recessed button initiates levels (modes) of reset on the DSC.
To initiate the different reset levels, use a pointed object such as a small Philips
screwdriver or a stylus to press and hold the button while the DSC is running or while
it is being powered up (see
Resetting ).
