Initializing the triport Class

A Triport, or 3-Wire Expander, is created by using the following constructor:

The triport constructor creates a triport object.

Parameter	Description
port	The port the 3-Wire Expander is connected to on the V5 Brain.

// Construct a 3-Wire Expander "Triport1" with the triport class.
triport Triport1 = triport(PORT1);

This Triport1 object will be used in all subsequent examples throughout this API documentation when referring to triport class methods.

Triports also have a letter attribute denoting the specific port in use. Each port is identified by a letter (a through h) and can be accessed using the format Triport1.x, where x is the port letter. For example, Triport1.a refers to the Sensor connected to the Triport’s port A.

Class Methods

installed()

The installed() command returns the status of what is installed on the port.

Returns: true if a 3-Wire Port device is installed in the port. false if one is not.
