Setup Procedures:
1. Connect the 5V DC 1A power transformer to the iSwitchHD Power Input connector. Connect the other end of the power transformer to an AC outlet.
2. Use an HDMI cable to connect the output of each source to one of the four iHDMI Inputs. Use another HDMI cable to connect the iSwitchHD Output to the display device (Figure 1).
3. Start the display device. Start one or more source devices (the corresponding Input LED will be ON). The last source started will automatically be connected to the display (the corresponding Input LED will PULSE). If desired, press the Select Button to manually change to a different source. Note: it may take minutes for some devices to start and a few seconds for the iSwitchHD and the display device to properly detect the HDMI signal.
4. For serial port control, connect a straight-wired (not Null modem) cable to the iSwitchHD Serial Port (Female DB9) and to the RS232 port of the controlling device (Computer, Home Automation Controller, etc.) Configure the controlling device for communication with the iSwitchHD (9600 baud, No Parity, 8 Data Bits, 1 Stop Bit, No Flow Control). Establish a connection and issue the proper commands to change sources or cable parameters (Figure 2). If using serial terminal software from a computer (Hyperterminal, ZTerm, etc.), press the “?” key to display a menu of the commands or simply enter the one-character command. Enter the “W” command to save the input/output settings when powered off.

Frequently Asked Questions
Q- How do I save or restore my settings through the Serial Port?
A- None of the Serial Port settings are saved until you use the Write To EEPROM (“W”) command. The
settings are restored from EEPROM when you power on the unit or use the Fetch From EEPROM (”F”) command. You can also restore factory Default Settings (”D”) if necessary.
Q- Automatic switching is great but how can I manually change the input?
A- Press the Select Button to manually change inputs; the unit will still automatically switch to new inputs
when detected. You can also use the Serial Port to select inputs 1 through 4 (”1”, “2”, “3”, “4”) but once you do, the unit will not switch automatically again until you use the Automatic Select (“A”) command.
Q- What can I do when one of my HDMI Input cables is long and the switch isn’t properly
detecting or displaying the signal?
A- You can set 12dB Input Equalization (”E”) for long input cables. Select input 1-4, then set the
equalization. When satisfied, save the setting (”W”) and place the unit back in auto mode (”A”). 6dB Input Equalization (”e”) is for normal length cables.
Q- What can I do when my HDMI Output cable is long and my TV is not properly detecting or
displaying the switch?
A- You can adjust the Output Pre-emphasis to 2dB (”L”), 4dB (”M”), or 6dB (”H”) depending on the length
and quality of the cable. You can also adjust the Output Current to 20mA (”C”). When satisfied, save the setting (“W”). 0dB Output Pre-emphasis (”N”) and Output Current 10mA (“c”) are for normal length output cables.
Q- What do the Pulse and Static Input Termination settings do?
A- They affect how the switch communicates with the input device when the input is selected. Pulse
Termination (”P”) causes a 100ms break in the signal so that the input device will reinitiate the connection sequence. Static Termination (”p”) does not have the break. You should not need to adjust them but they are available through the Serial Port if you do. Select input 1-4, then set the termination. When satisfied, save the setting (”W”) and place the unit back in auto mode (”A”).
Q- I don’t like the settings I saved through the Serial Port, what can I do to reset the switch?
A- You can reset the factory defaults by holding the Select Button while applying power. You can also
reload factory defaults through the Serial Port with the Default Settings (“D”) command and then save them with Write To EEPROM (“W”).
Q- What do the different Input LED conditions indicate?
A- OFF means there is no powered up input connected. ON solid means there is a powered up input
connected but it is not selected. SLOW PULSING means there is a powered up input connected and it is selected. FAST PULSING means there is no powered up input connected but it has been manually selected; select a different input. ALL FLASHING rapidly means that the output cable is not properly connected to the display device; reconnect it or change cables.
Q- How can I control the switch if my computer does not have a serial port?
A- You can use a USB to Serial adapter ( http://www.basicx.com/Products/usb1/usb1.htm ) or a Serial to
Ethernet device such as the SitePlayer Telnet System ( http://www.siteplayer.com/telnet ).
Q- What if I have more than 4 HDMI devices?
A- You can connect multiple iSwitchHD-4x1’s together to make a 7x1 (two units), a 10x1 (three units), a
NM-iSwitchHD-4x1
13x1 (four units), a 16x1 (five units), or even larger intelligent arrays.
