DB37F Connectors

I/O CONFIGURATIONS

The OP5700 simulator provides signal conditioning for up to 256 I/Os, which are managed from the

FPGA module and are accessible via DB37 and RJ45 connectors in the back and front of the chassis.

I/O lines are routed through a carrier board (inside the chassis) that can accept up to 8 signal conditioning modules, which provides greater signal conditioning flexibility. The conditioning modules follow a proprietary form factor, called Type B mezzanines. A range of mezzanines are available for analog and digital conditioning.

Mezzanines are detected at power up and information is processed by th FPGA for verification and initialiisation (I/O line direction, analog module calibration coefficients, etc.). Then, mezzanines are made available to the CPU simulation to detect improper configuration or hardware failure.

DB37F CONNECTORS

There are 4 groups of mezzanines, labeled 1 to 4; each pair (A & B) is linked to four female DB37 connectors (I/Os) on the back of the chassis:

The first two connectors (left to right) represent channels from Group B, which are linked to the conditioned channels from the rear mezzanine. The last two connectors (left to right) represent channels from Group A, which are linked to the conditioned channels from the front mezzanine.

I/O Configurations

DB37F Connectors

Two connectors (P1 and P2) are available for each mezzanine, and their depends on the type of mezzanine installed:

Analog modules (DAC or ADC), which use only 16 channels, which are routed through connector P1 and P2 does not carry any signals.

Digital modules (Din or Dout), which use up to 32 channels; the first 16 channels (00 to 15) are routed through connector P1 and the next 16 channels (16 to 31) are routed through connector P2.

All signals are represented by a positive-negative pair that are always available on the connector pins, for example: for channel 08 : (+CH08, -CH08)

Connector Interface:

Single-ended output: negative pin is connected to ground.

Single-ended input: user’s ground must be connected to the negative pin.

Differential output: positive and negative signals must be on positive and negative pins.

Differential input: connection must be between the positive/negative pair.
