- Connect one end of the flat cable to the loopback board
- Connect the loopback board to the simulator DB37 Output signal
- Connect the other end (DB37 connector) of the flat cable to the simulator DB37 Input signal
- Connect the VUser VUser* (required to preserve isolation) from the loopback board to the OP5700
* For more information about the use of Vuser and Vrtn pleaser refer to this article in the OPAL-RT knowledge base : How to power the different DB37 boards for digital outputs.

Note: Although some boards do provide a power source, using that would compromise the isolation. OPAL-RT recommends using external power source: the user must connect the power wires (provided) to either a 5 or 12 V power source. Make sure that the Vuser source switch on the loopback board is set to “External”. |
