Crestron MC2W 2-Series Professional Media Controller with RF
Analog input mode
•
4 analogs: < i1 > through < i4 >
•
For each analog, one corresponding minimum change value:
<
MinChange1 > through < MinChange4 >
All Versiport modes
•
For each Versiport, one corresponding pullup resistor: < pu-disable1 >
through < pu-disable4 >
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 >.

VersiPort 1
Digital Output Mode
When a Versiport is operating in digital output mode, the output pin is shorted to
ground on the rising edge of the corresponding <
o > signal (switch S1-B in the
Versiport diagram is 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 causes the output pin to float when <
o > goes low.
Example 1 (recommended):
The < pu-disable1 > signal is driven low or left undefined. When < o1 > goes
low, Versiport 1 is at +5V. When < o1 > goes high, Versiport 1 is shorted to
ground.
Example 2 (not recommended):
The < pu-disable1 > signal is driven high. When < o1 > goes low, Versiport
1 is floating. When < o1 > goes high, Versiport 1 is shorted to ground.
Digital Input Mode
When a Versiport is operating in digital input mode, the corresponding < i > signal
goes high whenever the C2I-MC2-IO4 detects that the Versiport is shorted to ground
(threshold < +2.5V).
