Rear Panel Description

Open

1. Power cord plug and master power on/off switch

2. 4x DB37 I/O connectors for I/O module in slot 1

3. 4x DB37 I/O connectors for I/O module in slot 2 (optional)

4. Ground screw

   • Please see Connecting the Ground Screw page in these pages

5. RS-422 DB9 connectors with 6 Rx and 6Tx

   • This is the default configuration. See below for other options available.

   • See here OP5969-1 RS422 Digital Inputs and Outputs (DIO) for specifications and pin assignments.

6. PCI Express Gen 2 x4 port:

   • This port is used to connect the FPGA in the OP4810-IO/OP4815-IO to another compatible OPAL-RT’s simulator.

   • The other device must have a OneStop communication card installed. See the Use Cases page in this section.

I/O Module Slots

Open

I/O Module Slots

Up to 2 I/O modules (or IO boards) can be installed in one of the two slot locations of an OP4810-IO or OP4815-IO FPGA Processor and I/O Expansion unit.

• Slots are identified Slot 1 and Slot2.

• If only one I/O module is installed, it is installed in slot 1.

• A second optional I/O module can be installed in slot 2.

I/O Module (or IO Board)

I/O Module (IO Board) Identification

• Module models are identified OP48Hxx, where “xx” is a number.

  • See available I/O modules here: OP48H00 I/O Modules Series for OP4800 Line of Devices

• SLOT x can be SLOT 1 or SLOT 2

• Each I/O modules provides four (4) DB37 connectors numbered P1 to P4. Each port is labeled with the type of IO:

  • Digital input (Din)

  • Digital output (Dout)

  • Analog input (Ain)

  • Analog output (Aout)

• The pin assignments for each channel depend on the type of module. They are described in the System Description Document delivered with the unit.

  • See also pin assignments here: OP48H00 I/O Modules Series for OP4800 Line of Devices.

Example

In this example:

• The I/O card model OP48H10 is installed in slot 1 of the unit (leftmost slot when facing the back of the device)

• Connector P1 and P2 include 32 digital inputs or outputs (Dio) numbered from channel 0 to channel 31

  • DIOs can be configured as inputs our outputs by groups of 8 (4 banks of 8 IOs)

• Connector P3 includes 16 analog outputs (Aout) identified channel 0 to channel 15

• Connector P4 includes 16 analog inputs (Ain) identified channel 0 to channel 15

Default I/O Module Configuration Suggested

• 1x OP48H10 Fast I/O, type H module

• Another OP48H10 Fast I/O, type H module can be installed optionally.

Standard and Optional I/O Connectors

The OP4810-IO/OP4815-IO comes with an RS-422 Connector Kit (OP5969-1) factory installed by default.

The optional Fiber-Optic Connector Kit (OP5969-2) can also be installed. It will replace the default connector.

Side Access Panel

The side access panel located on the left side of the device is reserved for OPAL-RT.
