OP5705-IO Front Interface

In the lower section of the unit, the OP5705-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 button with LED indicator.

C. 4 SFP ports (for MuSE or device interconnection) and status LEDs for each channel (LED 0 = channel 0):

Blinking green: an SFP module is plugged into the port and the bitstream is using Aurora for this channel
Continuous green: an SFP module is plugged into the port and the bitstream is not using Aurora for this channel
Blinking red: rx_loss is 1
Continuous red: tx_fault is 1 (these are SFP status signals)
OFF: no module plugged into the port and no Aurora present in the bitstream for this channel

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.

RJ45 cables connect from a channel on an RJ45 panel (A) to one of the four RJ45 monitoring connectors (D).
Mini-BNC connectors allow for quick cable connections to monitoring devices (such as an oscilloscope)
See OP5705XG Connecting Monitoring Devices for details.

F. USB JTAG for Artix7 FPGA (for OPAL-RT technicians’ use only).
