DB37F Connectors

Analog Mezzanines

DB37 connection to mezzanines

Each pair of mezzanines (A & B) is linked to four female DB37 connectors (I/Os) on the back of the chassis:

If the front mezzanine is a digital module (Din or Dout), the first 16 channels (00 to 15) are on the first connector, and the next 16 channels (16 to 31) are on the second connector.

If the back mezzanine is a digital module (Din or Dout), the first 16 channels (00 to 15) are on the first connector, and the next 16 channels (16 to 31) are on the second connector.

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

RJ45 Connectors

Each RJ45 monitoring panel on the front of the OP5650 simulator connects to front and back mezzanines. The following images illustrate how the mezzanines are linked to the connectors.

RJ45 Channel Assignments

Each mezzanine is assigned two columns of RJ45 connectors. Each column represents a series of channels, divided into 4 channels per jack, as shown in the figure below.
