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)

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.

LED	Power On	After Load & During Execution	After Reset
Tx	Off	Green**	Off
Rx	Off	Green**	Off
M/S	Default*	Orange = Slave	Green
PWR	Green	Green	Green

*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).
