This article describes remote control for the Velleman K8055 family of USB experiment boards.

Supported Velleman products are:

• K8055N
• K8055 (obsolete old version)
• VM110N
• VM110 (obsolete old version)

mAirList supports the five digital inputs for the triggering of remote commands.

The digital outputs can be used from a script.

Open the standalone config app, or the Control Panel, go to the Remote Control section, and add a new Vellemann K8055(N) remote.

The configuration dialog will look like this:

First, you can set up the device address (corresponds to the jumpers on the board) and the update interval for polling.

Then you can assign a command for each input 1-5, and for the event that the pin goes ON or OFF, respectively.

To access a K8055 remote from a script, use the following function:

function K8055Remote(iIndex: integer): IK8055Remote;

iIndex is the number of the K8055 remote set up in the system, with 0 being the first (and often) only one.

The function will return a reference to a IK8055Remote interface, which provides amongst others the following methods:

procedure SetDigitalChannel(Channel: integer);
procedure ClearDigitalChannel(Channel: integer);
procedure ClearAllDigital;
