Power Supply to the MR52-S3

The MR52-S3 accepts either 12Vdc or 12Vac for power. Locate the power source as closed to the interface as possible. Make power connection with minimum of 18AWG wires. The input voltage is filtered and regulated to 5Vdc or 12Vdc.

S1 DIP Switch Settings

1. The SCP-MR52-S3 has a DIP switch (S1) - this is used to set the address of the module. Switches 1 to 5 select the device address. Switch 6 and 7 select the communication baud rate (the default baud rate for SCP hardware is 38,400). All other configuration settings are set via host software.
   
   
   
   
2. The System Processor Module (i.e EP1502) is automatically assigned address 0 - You can see this if you enable Advanced View in the controller properties and look within the Miscellaneous section.
   
   
   
   
3. If the SCP-MR52-S3 is the first module on the RS-485 network you would therefore set S1 to address #1.
   
4. The SCP-MR52-S3 module communicates to an EP controller via the RS-485 communication link (TB6 connector) The interface allows for multi-drop communication on a bus of up to 4,000 feet (1,200 m).
   The RS-485 interface can be set for either 2-wire or 4-wire configuration via the J3 jumper. By default J3 is set to 2-wire.
   
   
   
   
5. To add an SCP-MR52-S3 to the system you must already have an EP controller added and online in the software.

6. With the EP controller highlighted, click on the MR52-S3 icon in the ribbon bar.

7. A dialog box will appear stating the exact model (SCP-MR52) - you also have the option of adding multiple DDMs but it defaults to just 1.

8. Click Accept and the MR52-S3 module will appear beneath the SPM in the hardware tree.

9. If the MR52-S3 is configured and wired correcting it should immediately come online.

10. You should also see events for the MR52-S3 in the Live Events grid.
