xiX adapters
1.1.
Overview
This manual describes the pin assignment of the PCIe adapters of the XIMEA xPlatform.
The basic idea of these adapters is to connect PCIe devices (mainly cameras) with a computer (processing unit).
The signal levels of the described connectors as well as the different cables (iPass, flat ribbon and Firefly) and their usage are not
explained here. For further information, please refer to the xiX camera series technical manual.
1.2.
Supported IO signals and voltage levels
xiX cameras support different trigger inputs and outputs depending on your cable connection (X2G2, X4G2 or X4G3).
A basic distinction is made between optically isolated inputs/outputs and non-isolated (TTL-like) inputs/outputs.
The isolated inputs/outputs require their own reference grounding. The signal levels of the non-isolated inputs/outputs use the
general ground level.
The non-isolated inputs/outputs can be defined as inputs or outputs by software.
In the xiX manual, the optically isolated inputs are referred to as IN1 - IN2 or OUT1 - OUT2 and the non-isolated inputs/outputs
are referred to as INOUT1 - INOUT4.
The names of the trigger inputs and outputs compared to the short names printed on the adapters and the names used in the xiX
manual are compared below:
