Installation

Place the OP5707-IO on a shelf or a desktop, or install it in a standard 19'' rack.
Connect all the cables as describe below.

• Make sure to respect proper grounding, as described in the Ground Screw section below.

• When installing an OP5707-IO in a system, it is important to have all connections completed before turning the unit on.

Connecting the Cables

These are the basic cabling instructions for your OP5707-IO.
Use the cables provided to connect your devices, as instructed.

MuSE Communication Cable

Use the SFP transceivers and LC-LC multimode fiber cable (sold separately) with the unit to connect one of the I/O Expansion Unit’s SFP ports to one of the real-time simulator’s SFP ports configured for MuSE communication.

• Unless otherwise specified in the System Description document of your unit, any of the 16 SFP ports can be used for MuSE communication.

• When using SFP ports for Generic Aurora communication with other OPAL-RT units or external devices, additional SFP modules and optical fiber cable are required (not provided).

Power Cord

Connect the power cord to the unit and plug it into an appropriate power source (outlet).

Ground Screw

You must connect a grounding cable from the OP5707-IO ground screw to the rack (or any other strong ground) to ensure that the unit terminates securely in a ground.
Proper grounding helps prevent electric shocks, protects the unit from voltage spikes (from a variety of causes, including lightning strikes), and provides increased immunity from EMI by lowering noise levels and emissions.

1. Select a flat braided grounding strap of adequate length (as short as possible provides the best protection), with ring terminals on each.

2. Attach one ring terminal to the ground screw on the OP5707-IO.

3. Attach the other ring terminal to the rack using a nut and lock washer.

DB37 Cables

Connect the DB37 cables from the OP5707-IO to external devices (motor, controller, etc.).

Testing I/O Signals

Before using your OP5707-IO, we recommend running the RT-LAB or HYPERSIM integration model delivered with your system.
If the I/O configuration is symmetrical (same type and the number of inputs and outputs), it is good practice to test I/O channels using the loopback board provided with the integration kit, which lets you read any feedback from outputs to inputs.

Connecting the I/O Loopback Kit

The loopback kit included in the starter kit allows users to test system signals. The connection is made easy with a custom flat cable that matches OPAL-RT standard DB37 pin assignments.

• Connect one end of the flat cable to the loopback board

• Connect the loopback board to the simulator DB37 Output signal

• Connect the other end (DB37 connector) of the flat cable to the simulator DB37 Input signal

• Connect the VUser (required to preserve isolation) from the loopback board to the OP5700

The breakout board provided allows users to access each pin of the DB37 separately through the screw terminals.
Simply insert the breakout board DB37 connector onto the desired DB37 connector on the simulator.

Refer to the system description document or the user manual of the OP5300 Mezzanine Modules installed in the system for exact pin assignments.
