IO92X, IO970-IO973 Pin Mapping

IO92X, IO970-IO973 Pin Mapping — Reference information about the I/O module connector

This section contains the pin mappings for the IO92x and IO970-IO973 modules.

The pin mappings of the high density resistor card connectors depend on the bit-resolution and the channel count.

The switches shown in the picture above are always closed, as soon as the model is downloaded to the target machine.

The calibration port is not supported by the current speedgoat driver.
