CHAPTER 2: Introduction to the HAL System Provides information about the health of the shielded CAT 5e connection between the DR4 and HAL or EXP1. The Comm LED (on the top row) lights solidly if the DR's data communications pair is working properly. The Power LED (on the bottom row) lights solidly if a HAL or EXP1 is supplying adequate power to the DR port. 5. Locate and Power LEDs The Locate LED flashes when toggled from within the Halogen software to help identify a specific DR4 - useful if you have more than one DR4 installed. The Power LED lights when adequate power is applied to the unit. NOTE: A DR4 is a 1U rack mounted device that requires a standard AC IEC power connection. DR5 The DR5 Switch Controller Remote provides eight Switch Input/LED Output pairs intended for use with a custom built lighted room combine switch panel. Switch Inputs These inputs on the DR5 are similar to the Logic In ports on a HAL. You can configure each of the eight input ports in one of two ways: l Toggle: The Toggle configuration allows you to control the state of a toggle control in the Control palette of the Processing Workspace. You can configure each port type to be either Momentary or Latching, which tells HAL how to process the port's input signal. For a complete description of Momentary and Latching toggle inputs, see "Momentary and Latching Toggle Configuration" on page 85. l Command: This option allows the Switch Input port to trigger a Command control in the Control palette of the Processing Workspace, which you can link to one or more Command controls such as a Command preset or a linkable button in a processing block property dialog. When nothing is connected to a Switch Input port, the hardware internally pulls the port to logic high (5 V). To trigger the command, a hardware device connected to the Switch Input port must pull the port voltage lower than the logic low threshold, which is specified in the data sheet for the DR5. One way to do this is to connect a physical normally open momentary push button switch to the port. When the end user pushes the button, the switch contacts close, pulling the Switch Input port low, which causes the Command to trigger. When the user releases the button, the port signal returns high and the port is ready for the next command. In addition, you can configure port 8 to serve as a 'lock' input, allowing the user to selectively enable or disable all seven input ports with a physical switch attached between Switch Input port 8 and ground (G). When configured as a lock, the DR5 disables Switch Input ports 1 - 7 when the switch is closed and enables the ports when the switch open. NOTE: To use the lock port, you must configure Switch Input 8 as a Toggle type of input. Once you have enabled the 'lock' port, you cannot move Switch Input port 8 or change it's type to Command.

Locate and Power LEDs
The Locate LED flashes when toggled from within the Halogen software to help identify a specific
DR4 — useful if you have more than one DR4 installed. The Power LED lights when adequate
power is applied to the unit.
NOTE
:
A DR4 is a 1U rack mounted device that requires a standard AC IEC power connection.
DR5
The DR5 Switch Controller Remote provides eight Switch Input/LED Output pairs intended for use with a custom
built lighted room combine switch panel.
Switch Inputs
These inputs on the DR5 are similar to the Logic In ports on a HAL. You can configure each of the eight input
ports in one of two ways:
l
Toggle:
The Toggle configuration allows you to control the state of a toggle control in the Control palette of the
Processing Workspace. You can configure each port type to be either Momentary or Latching, which tells
HAL how to process the port’s input signal. For a complete description of Momentary and Latching toggle
inputs, see "Momentary and Latching Toggle Configuration" on page 85.
l
Command:
This option allows the Switch Input port to trigger a Command control in the Control palette of the Proc-
essing Workspace, which you can link to one or more Command controls such as a Command preset or a
linkable button in a processing block property dialog.
When nothing is connected to a Switch Input port, the hardware internally pulls the port to logic high (5
V). To trigger the command, a hardware device connected to the Switch Input port must pull the port volt-
age lower than the logic low threshold, which is specified in the data sheet for the DR5. One way to do this
is to connect a physical normally open momentary push button switch to the port. When the end user
pushes the button, the switch contacts close, pulling the Switch Input port low, which causes the Command
to trigger. When the user releases the button, the port signal returns high and the port is ready for the next
command.
In addition, you can configure port 8 to serve as a 'lock' input, allowing the user to selectively enable or disable all
seven input ports with a physical switch attached between Switch Input port 8 and ground (G). When configured
as a lock, the DR5 disables Switch Input ports 1 - 7 when the switch is closed and enables the ports when the
switch open.
NOTE
:
To use the lock port, you must configure Switch Input 8 as a
Toggle
type of input. Once you have
enabled the 'lock' port, you cannot move Switch Input port 8 or change it's type to
Command
.
