Installation and Operation

Before permanently securing the unit for final installation of cabling behind walls or ceilings, test for proper operation of the unit and the cables in your system. It is recommended that you leave enough ventilation space to provide sufficient airflow and cooling, especially if you are going to leave the unit powered at all times.

Pushbutton Control

Your KD-HDSW unit may be controlled via the pushbutton on the front of the unit. Select your desired input by depressing the “Input Select” button. The front LED indicators (1, 2, 3, 4) correspond to the input that has been selected.

IR Remote Control
The KD-HDSW can also be operated using the IR remote control provided with your unit. The KD-HDSW switcher features IR sensors on the front and rear of the unit for reception of the IR command signals.

Serial IR & IR Emitter Control

• The “Serial IR” port requires the use of a Male 3.5mm Mono cable (not included) with the IR command signal being carried on the “Tip” of the input inserted into the KD-HDSW unit. The location of the IR signal may vary by control system used. Please verify the location of the IR signal with your control system.
• When using the IR Emitter / IR Extender (sold separately), the IR Emitter must be mounted over the IR Sensor on the KDHDSW unit. It is recommended that the rear IR sensor of theKD-HDSW unit be utilized for these applications. One end of the cable is connected to the IR Receiver / Master Controller / IR Extender / IR Connecting Block, while the other end is mounted over the IR Sensor of the KD-HDSW unit.

RS-232 Commands and Protocol

• KD-HDSW units are compatible with all Control Systems, such as AMX®, Control4®, Crestron®, RTI®, Universal®

• Connect your Control System’s Master Controller to the KD-HDSW unit using the RS-232 port.
  Follow all instructions provided with your control system.

• RS-232 Protocol:

  • Baud Rate = 9600 bits per second
  • Data Bits = 8
  • Parity = None
  • Stop Bits = 1
  • Flow Control = None

RS-232 Command List:

(01 – 99)

y = Input Select, Up, Down (1-4, 5, 6)

---|---|---
gir| Address Setting Status|
dir_y| Delete Address Setting per Command| y = Input Select, Up, Down (1-4, 5, 6)

• All RS-232 commands must be in lower case letters, require spaces where indicated above with ( _ ), and require a carriage return to be sent.

Multiple KD-HDSW Unit Configurations

Up to 99 individually addressable units can be installed. KD-HDSW switchers allow you to assign a two-digit address to each unit or each of the selectable inputs. This capability can be configured via IR or the RS-232 port.

• Addressing Buttons / Units via IR
  • With power enabled on the unit, press the “Power On” button. The “Input Select” LED lights will begin to blink, indicating that the KD-HDSW unit is ready to receive the address information.
  • Press the first digit (0 – 9) of the two-digit address. Once this first digit has been received “Input Select 1” LED will blink.
  • Press the second digit (0 – 9) of the two-digit address. Once this second digit has been received “Input Select 1” and “Input Select 2” LED’s will blink.
  • Press the Input Select button (Input 1 – Input 4, Up or Down) that you wish to assign the two-digit address to. Once this is completed, all “Input Select” lights will become solid indicating that the Input Select button has now been re-addressed.
  • Repeat Steps 2 through 4 if you wish to assign an address to additional “Input Select” buttons or to your entire KD-HDSW unit.
  • Press “Power On” button to exit addressing mode when completed.
• Addressing Buttons / Units via RS-232
  • See “RS-232 Commands and Protocol” section for RS-232 Addressing Commands
  • To address an Input, use “sir_x_x_y” command. To address an entire unit, repeat command for each Input, Up, and Down
  • For address settings, use “gir” RS-232 command to receive a list of address settings
  • To delete address settings, issue “dir_y” RS-232 command

EDID Control Settings

At times, your HDMI sources and display may not synchronize properly. This is when EDID* control should be utilized. KD-HDSW switchers feature an internal library of default settings that modify KD-HDSW input port’s EDID to ensure that your HDMI source’s output is compatible with your display.

NOTE: the DIP settings are 0 = down / off and 1 = up / on. Please reset the unit by either unplugging and plugging the HDMI connections, or via a power cycle for the new settings to take effect.

Dip Switch Configurations

EDID (Extended display identification data) is a data structure provided by a display to describe its capabilities to a source device.

Using iAS Intelligent Auto Sense™

iAS Intelligent Auto Sense™ will switch automatically when Hot Plug Detect signal becomes active on an input. iAS Intelligent Auto Sense™ can be enabled and disable via IR or RS-232 control. Please note that many common HDMI sources, such as a Cable or Satellite Box, will emit Hot Plug Detect signals when in stand-by mode and may prevent full functionality of iAS Intelligent Auto Sense™.
