This window permits to control all the I/O of the DL 1993A Acquisition board.
It is useful while testing the system.
It looks like in the figure:

In the window there are:

	Dig. I: contains the controls to display the states of the 16 digital inputs (ON-OFF). The first 8 inputs are connected to the test points of the 1993A Unit in the DIGITAL IN (TTL) section.
	Dig. O: contains the controls to set the states of the 16 digital outputs (ON-OFF). The first 8 outputs are connected to the test points of the 1993A Unit in the RELAY OUT section.
	Analog Outputs: contains the controls to change the values of the 8 analog outputs. The values are displayed as voltage values in the ranges 0÷10 V and -10÷10 V.
	Analog Inputs: contains the controls to enable and to display the 16 analog inputs. The values are displayed as voltage values in the ranges 0÷10 V and -10÷10 V.
