Serial IO Cards
QPS has performed a large number of extensive tests to investigate the internal latency of various (multi) IO Cards. For a complete description of these tests and how timing is done within Qinsy, read 'How-to Timing in Qinsy'.
The following Serial IO Cards have been tested by QPS. (Click on the model for more information)
When the result is 
, this doesn't mean that the IO card can't be used. If the message is time stamped or if the message is from a non-time critical sensor the IO card can still be used, especially e.g the Digi Xem which can have up to 64 ports.
