 +(To keep the editing effort as low as possible, all these units are referred to as //K8055// throughout the software and this documentation.) 
 + 
 + 
 +mAirList supports the five digital inputs for triggering of [[reference:remote_control_commands|remote commands]] directly. The digital as well as the analogue outputs can be used via scripting.

 ===== Configuration ===== ===== Configuration =====
 +
 +=== Digital Inputs ===
 +
 +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:
 +
 +{{ :config:remotecontrol:pasted:20160829-222415.png?400 }}
 +
 +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 [[reference:remote_control_commands|command]] for each input 1-5, and for the event that the pin goes ON or OFF, respectively.

 ===== Scripting ===== ===== Scripting =====
  
-To access a Velleman remote from a script, use the following function:+=== Digital Outputs === 
 + 
 +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 („zero-based“). 
 + 
 +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; 
 +   
 +''Channel'' refers to the digital channels, where ''1'' is the first one („one-based“). 
 +   
 +A complete call for switching on (setting) digital channel 3 on the first Velleman unit then should look like this: 
 + 
 +  K8055Remote(0).SetDigitalChannel(3); 
 +   
 +=== Digital Inputs === 
 + 
 +The status of the digital inputs can be read by the fucntions 
 + 
 +  function ReadDigitalChannel(Channel: integer): boolean; 
 +  function ReadAllDigital: integer; 
 +   
 +The former reads the status for each input individually, e. g. for channel 2: 
 + 
 +  K8055Remote(0).ReadDigitalChannel(2); 
 +   
 +whereas the latter gives a complete survey of all five inputs via the five least significant bits. 
 + 
 +Example: 
 + 
 +A value of 25 corresponds to inputs 1, 4 and 5 being set („on“) and inputs 2 and 3 being cleared „off“). 
 + 
 +  1 ⋅ 2⁰ + 0 ⋅ 2¹ + 0 ⋅ 2² + 1 ⋅ 2³ + 1 ⋅ 2⁴  =  1 + 0 + 0 + 8 + 16  =  25  
 +  ^        ^              ^       ^ 
 +  Bit 1    |       Bit 3    |       Bit 5 
 +  Inp 1    Bit 2   Inp 3    Bit 4   Inp 5 
 +           Inp 2            Inp 4 
 +   
 +=== Analogue Outputs === 
 +The analogue outputs can be actuated with the following method: 
 + 
 +  procedure OutputAnalogChannel(Channel, Value: integer); 
 +   
 +… where ''Channel'' resembles the number of the analogue output (i. e. ''1'' or ''2'') and ''Value'' is an integer value between ''0'' and ''255'': 
 + 
 +  * ''0'' leads to a voltage of 0V at the analogue or a duty factor of 0% at the PWM output, respectively. 
 + 
 +  * ''255'' leads to a voltage of 5V at the analogue or a duty factor of 100% at the PWM output. 
 + 
 +  * The effect of values lying in between these extremes can be characterised by: 
 +    * ''<Value> / 255 * 5V'' or  
 +    * ''<Value> / 255 * 100%'', respectively.
  
 +Notably the PWM output can be taken advantage of driving an ON-AIR lamp directly, as long as it meets the voltage and current limits of the transistor used in the circuit (BC337 that is, as of fall 2019).
