Section IV
ADVANCED OPERATING INSTRUCTIONS
The Quick-Start Setup section of this manual gave an abbreviat-
ed procedure for placing the JUSTIN 808 into service as quickly
and simply as possible. Quick-Start neglects the finer points of
setup and operation, but this section will explain the JUSTIN
808 in greater depth and introduce the numerous additional
features that are available, such as graphic displays, alarms and
error logging.
From this point forward, operation of the JUSTIN 808 will, in
large part, assume the use of the built-in Webpage server. Any-
thing (and more!) that can be done from the front panel can al-
so be accomplished using the Web interface, and bringing-up
the Web interface is as easy as entering the JUSTIN 808 IP ad-
dress into a computer, tablet or smart phone browser. The Web
interface and front-panel data entry share a common theme for
controls and readouts, and the use of either is really quite intu-
itive.
The Appendix (Page 42) gives a tabulated listing of all front-
panel OLED menu items. The front-panel menus parallel the
Web interface menus that will be referenced here, so this menu
listing is a good reference for basic understanding of the unit.
JUSTIN 808 REMOTE ACCESS NOTES
To access the JUSTIN 808 on a common local network (LAN),
just enter its IP address into your browser’s address bar.
But to address the JUSTIN 808 from
outside
your LAN (from the
Internet), the unit must have a static IP address. If your router
makes DHCP assignments for other equipment on the network,
simply assign the receiver a static IP that is outside the router’s
DHCP group range. This should be an easy matter with the aid
of the router’s Help utility. A static IP address for the JUSTIN
808 is entered on the
Network
submenu. Switch
Mode
: from
DHCP
to
Static IP
and type-in the requisite information.
Port Forwarding
It will be necessary to specify a port for the JUSTIN 808 on the
network router. Within the router’s Port Forwarding utility you
are able to enter your static IP address for the unit (Internal IP),
followed by a colon and a port number. The port number may
be any number in the router’s range.
If your Internet Service Provider (ISP) assigns you a static IP ad-
dress, then it is a simple matter to address the JUSTIN 808
