class RelayInterface():

""" This class provides a common interface for controlling relays on Extron devices (extronlib.device). The user can instantiate the class directly or create a subclass to add, remove, or alter behavior for different types of devices.
|
|
|
|
Arguments:
|
|
Host (extronlib.device) - handle to Extron device class that instantiated this interface class
|
|
Port (string) - port name (e.g. 'RLY1')
|
|
|
|
Parameters:
|
|
Host - Returns (extronlib.device) - handle to Extron device class that instantiated this interface class
|
|
Port - Returns (string) - port name
|
|
State - Returns (string) - current state of Relay port ('Close', 'Open')
|
|
|
|
Events:
|
|
Offline - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Offline').
|
|
Online - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Online').
