User Interface Getting Started COMMUNICATING 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. NETWORK ACCESS 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 patterns. 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. http://[IP Address] 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. http://[IP Address]/config The JNIOR supports the HTTPS:// secure protocol as well. SERIAL ACCESS 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 Parity. The IPCONFIG 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, the device. NOTES 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.
