SCXI-1502 User Manual
If the scanned SCXI-1502 module is not directly cabled to the DAQ device,
the module sends its signals through the SCXIbus to the cabled module.
The cabled module, whose routing is controlled by the SCXI chassis, routes
the SCXIbus signals to the DAQ device through the AI 0 pin on its rear
signal connector.
If the DAQ device scans the cabled module, the module routes its input
signals through the AI 0 pin on its rear signal connector to a single channel
on the DAQ device.
