In order to enable the web access feature:
Depress MAIN MENU key.
Scroll to NET menu and depress ENTER.
Using the soft keys, navigate to the ADVANCED menu (NET→ NEXT→ ADVANCED).
The WEB ACCESS option should be highlighted.
Use the UP/DOWN ARROW keys to enable or disable the feature.
After saving the change, you will need to reboot the Classic by removing PV power and
battery power with the 2 disconnects and waiting for the screen to go dark. Wait 30 seconds
and re-apply PV and battery power.
The WEB ACCESS selection indicates the current setting of the feature (i.e., ENABLED means the
feature is currently in operation).
You will need the values of MA and DI handy in order to create an account on the My MidNite web
site. This unique number pair identifies your particular Classic to our server and helps to prevent
malicious users from trying to access your Classic. The DI or (Device ID) is different than your
Classic’s serial number.
Local Network
Note that your Classic identifies itself by name to DHCP-enabled routers as “Classic.” There is
facility to change the name of a given Classic via the local and web-based interfaces as well as using
third-party MODBUS software packages.
Advanced
The Classic advertises its address every 10 seconds using the UDP protocol. Advanced users and
programmers may use this feature to identify Classics on their network.
Battery Temperature
Battery Temperature Compensation
The Classic comes with a battery temperature sensor (BTS). This sensor raises or lowers charge
voltages based on temperature. Connect the BTS to the BATT TEMP jack. The Battery Temperature
menu appears as T-Comp in the BATTERY MENU. In this menu you can change the voltage
compensation as needed. If the BTS is disconnected or shorted the Classic will automatically default
to 25C on the battery temperature. The Classic also has the ability to change the neutral temperature
(typically 25C); this setting can be found in the WBJr set-up menu.
