These inputs on the DR4 are similar to the Logic In ports on a HAL. You can configure each of the eight input ports in one of three ways: toggle, command, or selector.
The Toggle configuration allows a Toggle command with an on/off switch. You can configure each port type to be either Momentary or Latching.
The Command configuration allows triggering a Command control from an on/off switch, which can link to one or more Command controls such as a Command preset or a linkable button in a processing block property dialog.
The Selector configuration uses either a multi-position switch or a binary switch. You can connect a physical device to any or all of the Logic In ports and configure the ports in Halogen so that they make the desired selection according to the state of the physical device. Wiring details are in the Halogen Software Help.
You can configure each of the 8 output ports in one of 2 ways:
- Toggle: When a toggle control in the Halogen Control palette is unchecked, HAL sets the corresponding DR4 Logic Out port to logic high (5 V), and when the toggle is checked, it sets the port to logic low (0 V).
- Selector: When a selector control in the Halogen Control palette is set to the first selection, HAL sets the corresponding DR4 Logic Out port to logic high (5 V). Conversely, when the selector control is in the second position, HAL sets the port to logic low (0 V).
Analog Control Inputs
Each port allows an analog voltage source to control the value of a Level control in the Halogen Control palette. The input range for the port is from 0 V to 5 V, where 0 V corresponds to 0% on the associated Level control and 5 V corresponds to 100%. Connect a physical linear-taper potentiometer; the Vc wiper provides the control voltage to the DR4. As you adjust the pot the voltage changes, which in turn changes any linked Level control in Halogen.
IR Remote Inputs
The IR ports are ideal for linking to the wall toggle controls in a Room Combine block, allowing automatic room configuration changes to occur as moveable walls change positions in a physical room. These ports are read-only, intended for the Rane IR2 (see its data sheet). When the IR Remote is sensing infrared the wall is considered ‘open’ and the associated toggle control in the Hardware Controls palette is checked.
