Programmable Serial Controller

3. Getting Started
The HR-4P is a configurable Input/Output Controller device that for most installations is
configured to detect either a dry contact closure or a DC voltage and then send a pre-
programmed serial string to some device, typically a projector.
The unit comes from the factory setup with all 4 I/O lines configured for dry contact
closures and no pre-programmed actions.
You should be prepared with the necessary information and equipment to test
your installation prior to being put into service.
• If the HR-4P will be used to control a serial device, the required control codes
for that device should be obtained. For example, the code to turn on and off the
Projector.
• If the HR-4P will be used to interface to other electrical equipment such as
contacts, compatible power sources or outputs, the supporting electrical
information will be required. For example, an electrical schematic or drawing
that shows how the HR-4P to the other electrical equipment such as switches
or relays.
• A Windows™ compatible PC is required to program the HR-4P unit. Once
programmed, the PC is no longer required except when testing and
troubleshooting installations.
• Test the programmed units to ensure functionality before the final installation.
Select the desired interface for each of the I/O lines that will be used to control the HR-4P
unit. These are set on the I/O Tab of the GUI and then uploaded into the HR-4P unit.
• Switches or Relay Contact Interface – Select the ‘INPUT - CONTACT’ type
• External DC Power Sources – Select the ‘INPUT – VOLTAGE’ type (9-28 vDC)
• Relay Coils – Select the ‘OUTPUT’ type (each output can provide 40 mADC of
current)
See examples of connection wiring at the end of this manual.
The HR-4P unit must be programmed before being put into service to control
something. The programming is accomplished using GUI software installed on the
users PC. Follow the instructions below for installing the software GUI.
