LE/LE-HC Series DVR User Manual
V1.4 October 2006
DVR is required if the light is off, and pushing the connector turns the light on. These lights will
usually be located right next to the connector plug on the DVR, and there are usually a bank of
lights on the router that show valid connections. If in doubt, unplug the cable and see if one of the
lights goes out.
Once a physical connection has
been established, the next thing
to check is the network settings.
The first step is to bring up a
DOS prompt. From any
computer on the network, click on
the start button and click on run.
(Windows™ 2000, XP). Type in
"command" and click OK. This
will bring up a DOS prompt.
Type in "ipconfig /all", and press
enter. If all goes well, Figure 3.2.
The information needed is the
subnet mask, default gateway,
Figure 3.2
and DNS Servers. Note the IP
addresses. The number after the last "dot", e.g. in 192.168.0.20, the number 20 is the one to
change for the DVR. Picking a number above 200 (max is 254) should be OK, unless the unit is
being installed in a large networking environment. In that case, they will have a network
administrator who knows the exact settings required.
The LE/LE-HC Series can be assigned a dynamic IP by a DHCP Server (usually a router or
Windows 2000 Server) by assigning the DVR IP address 255.255.255.253. This does give the
added complication of finding out what IP was assigned, and while there is software that can
locate the LE/LE-HC Series DVR on the network, it is easier to assign a static IP.
