2-Series Integrated Dual Bus Control System
Crestron
AV2 & PRO2
In Program Manager, drag the C2I-IO8 symbol from
Program View
to
Detail View
.
The symbol contains the following signals, arranged here according to mode:
Signals
Digital output mode
•
8 digitals: <
o1
> through <
o8
>
Digital input mode
•
8 digitals: <
i1
> through <
i8
>
Analog input mode
•
8 analogs: <
i1
> through <
i8
>
•
For each analog, one corresponding minimum change value:
<
MinChange1
> through <
MinChange8
>
All Versiport modes
•
For each Versiport, one corresponding pullup resistor: <
pu-disable1
>
through <
pu-disable8
>
Defining a signal puts the signal into the corresponding mode. For example, defining
the analog input <
i1
> configures that Versiport as an analog input. A Versiport can
only operate in one mode. That is, if you define <
o1
> you should not also define
<
i1
>.
Description
Internal configuration of a Versiport
Digital Output Mode
When a Versiport is operating in digital output mode, the output pin will be shorted
to ground on the rising edge of the corresponding <
o
> signal (switch S1-B in the
Versiport diagram will be closed). When <
o
> goes low, the output pin is driven to a
value of +5V (switch S1-B is open).
Driving the corresponding <pu-disable> signal high can modify this behavior. This is
not recommended, though, since it will cause the output pin to float when <
o
> goes
low.
