 ===== Scripting =====
+=== 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.
+''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:
@@ Line 40: / Line 55: @@
   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“).

+=== 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).
