OP5707-IO Front Interface

In the front of the unit, the OP5707-IO 2nd Edition has one round button with an integrated LED indicator (B), while the 1st Edition has a toggle switch with LED indicator (B) above.

A. RJ45 connector panels provide connections to monitor signals from I/O modules.

• Each connector is linked to one I/O module on the carrier board.

  • Analog I/O modules (channels 0-15) will use only the first column of connectors.

  • Digital I/O modules will use both columns:

    • Channels 0-15 in the first column

    • Channels 16-31 on the second column

• See the RJ45 Connectors section in the IO Connectors page for detailed information.

B. Power switch/button with LED indicator

C. SFP (Small Form-factor Pluggable) ports controlled from the FPGA, for MUlti-System Expansion (MuSE) communication with other FPGA simulators or with third-party devices.

• Each socket controls one communication link.

• SFP transceivers and fiber optic cables must be selected according to the type and speed of the communication protocol implemented in the FPGA (OPAL-RT MuSE link or third-party device connection).

• MuSE link requires specific SFP and cable:

  • SFP: Avago AFBR-57R5APZ

  • Cable: LC-LC multimode 850 nm optical fiber

• The LEDs (light pipes) associated with the selected channel will light to indicate the channel is selected.

• LEDs are arrow-shaped to indicate the channels to which they are associated.

  • The LED upward arrow points to the top channel

  • The LED downward arrow points to the bottom channel (see below)

LED	Color	State Description	Open LED display
or or	Green Red	ON: SFP is inserted | OFF: No SFP is present | BLINK: Channel active OFF: Connection OK | ON: transmission fault | BLINK: Reception loss

D. Synchronization connectors (fiber optic and audio) and a series of four LEDs on the front panel display the device status.

*The color of the LED on power-on depends on the default FPGA configuration:

• When the FPGA board is programmed in Slave synchronization mode, the LED will be orange.

• When it is programmed in Master mode, the LED will be green.

**Tx and Rx provide synchronization information.

• When transmitting the synchronization signal, the Tx LED will be green.

• When receiving the synchronization signal, the Rx LED will be green.

E. RJ45 connectors with mini-BNC terminals for monitoring.

• Mini-BNC connectors allow for quick cable connections to monitoring devices (such as an oscilloscope).

F. USB JTAG for VC707 FPGA (for OPAL-RT technicians’ use only).
