The Abilis permits to pilot Output digital line and Relay switch ports making phone calls. For that we use a LUA script joined to DISA MODE:APP resource that allows to open Gate#1 connected to Relay switch ports 1-A, 1-B. By enabling the digital output line (ON) a contact is closed that short-circuits the respective A and B pins.

	Note
	This advanced configuration normally is realized by Second Level Abilis support. Bellow are reported only the resource configurations and a short logical description.

	Tip
	Interesting chapters: Section 16.3.4, “Activating the RIO device”; Section 63.14, “LUA scripts”.

1 - The Abilis verify to receive a call to the called number 40x, for example 401 to pilot D-OUT:1.
