Local user control is from a LAN via RJ-45 Ethernet or the front-panel LCD/keypad. All
settings may be presumed to be retained through power cycling unless otherwise speci-
fied. This means that they are still in effect through resets, whether by power outage, com-
manded reset, or failure-recovery resets.
3.2 Ethernet/Web Browser Control
The DTV 720’s primary user interface is from a web browser using the rear-panel Ethernet
LAN connection. An HTML script interface allows a user to control and monitor the unit
using a standard web browser. Each unit contains a user-defined quad URL address, sub-
net mask, and gateway address (See Table 3.1: DTV 720 IP Setup.)
There are two basic methods of using the Ethernet connection – with a directly connected
PC or with a PC connected through a LAN.
Directly
Connected
PC
For control from a local PC, attach the DTV 720’s Ethernet port to the Ethernet network
connector on the PC using a crossover RJ-45 cable (8 pins).
Before using this Ethernet connection, the appropriate IP address, netmask, and gateway
must be selected via the front-panel interface.
