User Interface Getting Started
In order to configure and program the JNIOR you will need to communicate
with it. The JNIOR has no keyboard or display interface. There are ways to
interact with the unit both serially and through the network.
In order to fully interact with the JNIOR and use its WebUI you must properly
configure the unit to operate on the network. JNIORs are now being shipped
from the factory with Dynamic Host Configuration Protocol (DHCP) enabled. With
a network supporting DHCP the JNIOR will obtain a valid IP address and
automatically configure itself properly for the network. You will still
need to determine the IP address that it has been assigned.
One unique method uses the orange status LED. If you know the first 3 octets
of the IP addressing used by the network you can determine the forth octet and
therefore the full IP address assigned to the JNIOR. Connect the JNIOR to the
network and power it up. After a couple of minutes disconnect the network
connection leaving the unit powered. The status LED will flash the digits of
the last octet in Morse Code! See the MORSE_CODE
reference for the digit
You can download the JNIOR Support Tool from the Downloads area under
Support on the website jnior.com
. The Support Tool uses the Beacon
Protocol to communicate with JNIORs on the local network segment. The active
JNIORs on the network are listed under the Beacon tab. This protocol does not
require that the JNIOR have a valid network configuration. A JNIOR even if
configured for a foreign network will appear in the list. You can right-click
on a JNIOR and select Configure and IP Configuration to establish settings.
Once the IP Address of a JNIOR properly configured for the network is known
you may enter the following URL in a browser to activate the Dynamic
Configuration Pages WebUI.
The WebUI is distributed as the file /flash/www/config.zip and the default
setting of the Registry Key /WebServer/Path is /flash/www/config . This
allows the simple use of the IP address (or hostname) in the URL to locate
the supplied WebUI.
If the JNIOR has been previously configured to support a custom Website you
may bypass that site and reach the WebUI with the following URL.
The JNIOR supports the HTTPS:// secure protocol as well.
In the absence of a network connection you can reach the Command Line
Interface (CLI) or Console through the COM serial port. A USB-to-Serial
adapter may be used as PCs these days do not provide serial ports. The
communications parameters are 115,200 Baud, 8 Data Bits, 1 Stop Bit and No
command at the command line can be used to determine and
alter the IP configuration of the JNIOR. This command may be necessary in
establishing proper network addressing if DHCP or the Support Tool cannot
be used. For example: The JNIOR may be connected to the network using a
cellular modem or other wireless approach not supporting the broadcast
required by the Beacon protocol.
The CLI is quite powerful in many ways and not just for configuration although,
the network is still required for transferring files either on to, or off of,
A network cable can often be used to connect the JNIOR directly to a PC.
The Support Tool running on the PC will locate the JNIOR and allow
you to configure the unit.
