CHAPTER 2: Hardware Component Details Logic Out ports are used to signal another device. A common implementation is to link a Logic Out port to a Toggle control in Halogen so that an end user can change its value from a DR remote, for example. Also, the Halogen software contains a checkbox for each Logic Out port, the value of which you can include in a preset or link to another control, making it possible to use a preset or control to turn the Logic Out port high (toggle unchecked) or low (toggle checked). 6. Logic In Ports Use these TTL 5-volt digital logic input ports to communicate to the HAL System via an external control device. You can configure each Logic In port to control a selector, toggle, or command within the HAL System. For example, you might use a Logic In port to select between two audio channels, or to mute the whole system. 7. IR Remote Ports Use these ports to connect each IR Remote to the DR4 via a standard shielded CAT 5e cable. You must use a standard Ethernet cable for this connection. Front Panel 1. IR Remotes LEDs Provides information about the IR Remote inputs. The numbers at the top of the front panel correspond to the IR Remote ports on the back of the DR4. For example, the LED for number 1 provides information about the IR Remote connected on port 1.Under each IR Remote number is an LED for the state of the connected IR Remote. When the remote is sensing infrared, the DR4 turns on the corresponding LED on indicating that the wall is Open. When the remote does not sense infrared, the wall is closed and the LED is off. 2. Logic In LEDs Provides information about the DR4 Logic Inputs. The numbers at the top of the front panel correspond to the DR4 Logic In ports on the back of the DR4. For example, the LED for number 1 provides information about the Logic In port 1.Under each Logic In port number is an LED for the state of the Logic In. When the Logic In signal is at logic high (> +2 Volts) the LED is off and when the signal is at logic low (< 0.9 Volts), the LED is on. 3. Logic Out LEDs Provides information about the DR4 Logic Outputs. The numbers at the top of the front panel correspond to the Logic Out ports on the back of the DR4. For example, the LED for number 1 provides information about the Logic Out port 1.Under each Logic Out port number is an LED that indicates the state of the port. When the associated toggle control in the Control palette of the Processing Workspace is unchecked, the DR4 sets the port to logic high and the LED is off. When the toggle is checked, the DR4 sets the Logic Out port to logic low and the LED is on. 4. Digital Remote LEDs 55
