Upper section

A. Small form-factor pluggable (SFP) module connectors provide four high-speed communication links between other FPGA simulators or third-party devices. Each socket controls one communication link. SFP transceivers and fiber-optic cables must be selected (and purchased separately) according to the type and speed of the communication protocol.

  • Note: MuSE link requires specific SFP transceivers and optical fiber cables:

    • SFP: Avago AFBR-57R5APZ

    • Cable: LC-LC multimode 850 nm optical fiber

B. JTAG connector (for OPAL-RT technicians’ use only).

  • Note: JTAG connector is highly sensitive to Electro Static Discharge (ESD). Always leave plastic plug in place when not in use. Wear an anti-static wrist strap at all times when using this connector.

C. Synchronization connectors status and user-configurable LEDs, dip switch and synchronization connectors.

  • LED Label

    • PROG/CFG OK:

      • CFG OK steady on green and PROG off indicates the FPGA is functioning normally.

      • CFG OK off and PROG steady on yellow indicate the FPGA has stopped and is no longer functioning.

    • RXGreen when receiving synchronization.

    • TX: Green when transmitting synchronization.

    • USER 1: Green LED controlled. Configured by the user using Simulink blocks.

    • USER 2: Green LED controlled. Configured by the user using Simulink blocks.

    • PWR ON: Green indicates that the power is on.


      • Green indicates MASTER mode.

      • Yellow indicates SLAVE mode.

      • Flashing green and yellow indicates a SAFE bitstream in the FPGA

  • Dip switches

    • CHASSIS INDEX: 8-pin DIP switch that allows users to set the device’s network chassis index.

      • It can be set from 00 to FF (in HEX) or 0 to 255 (in decimal) for a maximum of 256 addresses.

      • Otherwise specified in the “System description” document delivered with your system, the default value = 00.

      • Refer to General Configuration to copy this value in RT-LAB.

      • Set the dip switches in binary code on 8-bit to change the chassis ID number. Switch down is 0 and switch up is 1

  • SYNCHRO Connectors

    • TX/RX Fiber-Optic Connectors (square connectors): Compatible with OP4500, OP5607, OP7000 and OP7020. Synchronizes time steps between systems and includes high-speed FPGA pulses.

    • TX/RX Copper Cable Connectors (3.5 mm audio jack connectors): Legacy connectors compatible with all OPAL-RT products except OP4200, OP5705, OP5650.
