5) Restore computer TCP/IP settings to their original settings
When finished with direct connect communication restore the computer’s original Internet Protocol (TCP/IP) Properties settings recorded
above which are likely Obtain an IP Address Automatically and Obtain DNS Server Address Automatically. If these settings are not restored the
computer will not be able to communicate with a hard wired connection to the router or the internet. Be certain to reconnect the computer to the
router with a standard patch cable as the crossover cable supplied with the UCM will not work for this purpose unless the router can detect and
correct for a crossover type cable.
UCM CONNECTION USING A ROUTER
This option allows one or more computers to connect to the UCM via your router and LAN (Local Area Network). Special communication settings may be
required in the UCM, router, or both to allow UCM access over your LAN. Computers on your LAN must be able to communicate with the UCM through the router
before attempting to communicate with the UCM over the Internet.
1) Connect UCM to powered charge controller with 4-pin telephone cable supplied
Confirm heartbeat/power LED is blinking indicating charge controller is powered and UCM is powered and operating.
3) Connect UCM to ROUTER
Connect UCM to an available port on the Router with a user supplied standard CAT-5 network patch cable. The crossover cable supplied
with the UCM cannot be used for this purpose and a straight-thru cable is required unless the router can detect and correct for a crossover type
cable. Confirm the LINK LED on UCM’s Ethernet connector is ON and the Router’s link active indication for the port being used is ON indicating a
communication link is established between the Router and UCM.
2a) Attempt to logon to the UCM’s web site
From a computer attached to the Router enter the UCM’s IP Address into the web browser. The UCM uses a fixed IP Address with a factory
default IP Address of 192.168.1.235 which may be changed if desired on the UCM Setup page. For Windows Internet Explorer enter the web
address in the form;
http://192.168.1.235
If you are presented with the UCM’s password logon screen as shown above the UCM is communicating across your LAN and further router
or UCM setup for LAN communication is unnecessary. If you are unable to get to the password screen because the IP Address or other UCM
communication settings may have been changed, perform a Restore As Shipped Factory Defaults function and try again.
2b) Modify router configuration if necessary and logon to the UCM’s web site
If you are still unable to get to the password screen the UCM and/or router may require special settings to allow the router to communicate
with the fixed IP Address UCM. Refer to the router’s documentation regarding communication setup for fixed IP Address devices. However, many
routers require two things be changed, 1) Change the UCM’s IP Address to be within the IP Address range the router can assign via DCHP, and
2) Add the new UCM IP Address to the routers DCHP Reservation list to reserve the UCM’s new IP Address for exclusive use by the UCM.
¾ A direct connection between the UCM and a computer using the supplied crossover cable as described previously is
necessary to configure UCM communication settings including the IP Address. If you are unable to get to the password screen
because communication settings in the UCM have been changed you can temporarily force the UCM to use default
communication settings by rebooting the UCM with DIP #4 IP-A turned ON. This special communication mode will temporarily
show and use default communication settings on the UCM Setup page. If no changes are made at this time, previous changes
made to these settings will return following reboot with DIP #4 OFF. If settings changes are made at this time such as changing
the IP Address the new settings will be used following reboot with DIP #4 OFF You may also restore all UCM defaults including
communication settings and password by performing a Restore As Shipped Factory Defaults function.
Record the UCM’s new IP Address for later use.
