Connection Between the Host Computer and the OPAL-RT Simulator
See also this page Connecting your Real-Time Target Node to your Network in the RT-LAB user documentation.
The host computer and the OPAL-RT simulator (i.e. target) can be linked in several ways, as shown in figure 1 below.
...
LAN Connection: In this configuration, the host computer communicates with the OPAL-RT simulator through a Local Area Network (LAN). This connection allows the host computer to locally or remotely manage or have access to more than one real-time simulator connected to the LAN. Conversely, multiple host computers running RT-LAB can access a simulator through this configuration (Figure 1a).
Network switch connection: The simulator target and the host computer can be connected to the same physical network switch, which in turn does not need to be connected to a LAN (Figure 1b).
Direct connection through Ethernet interface: If there is no need to access the real-time simulator from multiple terminals or if simply neither a LAN nor a network switch is available, users can directly connect the host computer and the simulator through an Ethernet adapter (Figure 1c). A standard Ethernet cable suffices if the host’s Ethernet adapter supports Auto-MDIX(Auto-Medium Dependent Interface Crossover), which is the case for most modern equipment. Users are advised to verify the system documentation. In case the adapter does not support Auto-MDIX or if the user is not sure, an Ethernet crossover cable must be used (Auto-MDIX will also support a crossover cable). Further instructions on the configuration of the host computer are covered in Appendix 3: Direct Ethernet connection between the OPAL-RT simulator and a host computer here.

OPAL-RT OP8219 Inverters/Decoders Interface Panel provides two 6-pulse inverter outputs that can control Festo 8857 IGBT inverters.
The voltage levels of the inverter outputs are specifically conditioned to directly drive the 8857 inverter.
Connection between the OP8219 and the 8857 inverter is straightforward: employ the provided DB9 cables to connect the selected OP8219 inverter output to the corresponding inverter input in the 8857 inverter, as shown in figure 4.

OP8662-8-600 High Voltage and Current Probe
Connect both the OPAL-RT simulator and the OP8219 OP8662-8-600 high voltage and current probe to a 120/208 240 AC power outlet.
The back of the OP8219 displays a set of 4 LEDs indicating that all the DC levels (+5, +12, and ±15 V) required for the correct operation of the OP8219.
OP8219 Inverters/Decoders Interface Panel
Connect the OP8219 inverters/decoders interface panel to a 12 VDC source using one of the three connectors on the back of the board.
