Figure 4
Connections to power supply and battery
The controller comes with a 12Vdc power supply which gets connected to the top of the board.
The controller also has a battery voltage monitor should you wish to monitor the status of the
battery.
When the power is connected the power indication LED in the middle of the board will turn on.
NOTE:
Please ensure that the power is switched off whenever wiring things like digital outputs in
order to protect the board from accidental shorts or power spikes.
Step 2: Set the address using the configuration menu
The SDC-650 communicates with other controllers via a multi-drop RS-485 communications
network. Each controller on this network requires a unique address for communications and
identification. Duplicate addresses will cause communication problems.
The address of the controller can be a number from 0 to 15. This setting can be adjusted using the
menu on the configuration panel.
Press the R
ight button until a page headed ‘Node address’ is visible.
Press the Enter button to edit the value.
If the password is required the password page will be shown
– enter the password as
explained in the section above entitled ‘The configuration and diagnostics OLED panel’.
Press the Up and Down buttons to select the correct node address.
Press Enter to save the changes temporarily to memory.
In order to save this change for reboot, browse through the pages until you get to a page
entitled ‘Save Settings’. Press Enter to execute the save action then reboot the controller
for the change to take effect.
Note:
This address will be the same address as used in the SACS software.
