7. Inputs and outputs interface
7.1. Overview
All input and output signals pass through the GPIO (General Purpose Input and Output) module.
The GPIO module consists of a Look-Up Table (LUT – Cross-Point Switch), 2 Pulse Generators
and a 12-bit counter. In the LUT, the relationship between inputs, counters and outputs is
governed by internal register set-up.
Fig. 9 Cross point switch
7.1.1 LUT (Cross Point Switch)
The LUT works as a cross-point switch which allows connecting inputs and outputs freely. The
signals LVAL_IN, DVAL_IN, FVAL_IN and EEN_IN all originate from the camera timing circuit.
On this diagram, Trigger 0 is used for exposure and Trigger 1 is used for Delayed Readout. The
Time Stamp Reset signal can reset the time stamp specified in GigE Vision Format. This signal
can be used when time stamps from several cameras connected are coincident with each other.
