Digital Inputs
The V2+ includes 16 inputs (8 button inputs and 8 Opto-isolated inputs) that can
help control the flow of a show system. The button inputs are activated by
pressing the corresponding front panel button (button 1 corresponds with input
1, etc.), and the Opto-isolated inputs are activated by electrically activating the
input through the Parallel I/O connector located on the rear panel. The
connections for the Parallel I/O connector are as follows:
Pin Connection Pin Connection
1 Voltage Input 9 20 Voltage Input 9 Return
2 Voltage Input 10 21 Voltage Input 10 Return
3 Voltage Input 11 22 Voltage Input 11 Return

Table 6 – Parallel I/O connector Inputs.
Two forms of input signal can be applied to the Parallel I/O connector: Voltage
Inputs, and Contact Closures. Voltage Inputs and Contact Closure Inputs, while
activating the same input, are available on separate pins of the Parallel I/O
connector. They are intended to be used separately. Applying both a Voltage
and a Contact Closure to the same input simultaneously may damage the unit.
