Mounting bracket x 2
The HD-SC-500 comes with mounting brackets that can be used to affix the unit to a table, desk,
etc.
To affix the mounting brackets to the unit, use the four included screws. The bracket can be
affixed with the oval holes pointing to the bottom (for against the wall - picture A) or the oval holes
facing the top (for under tables - picture B).
Larger oval
hole will be
attached to
the wall/table.
Mounting
Circular holes
will always be
attached to the
unit.

The captive screw connectors allow you to cut cables to a suitable length, reducing cable clutter
while providing a more reliable connection.
Captive Screw
Connecting
The captive screw connectors have
a contact bar that is adjusted to
compress the wire against the top
contact plate. Use the screws at the
top of the connector to compress
the wire against the contact plate.
When connecting the cables to the female captive screw connector it is important that the wires be
terminated correctly. The female captive screw connector has a contact plate at the top and must
have the wires touching it for signal to pass. When wired correctly (see picture A) the signal will pass,
incorrectly (see picture B) no signal will pass.
Clockwise Counter
Clockwise
Turn the screws clockwise to
raise the contact bar to the
upper contact plate and hold
the wires in place.
Turn the screws counter
clockwise to lower the
contact bar to release the
wires.

Analog Audio
A captive screw analog audio connector is provided to ensure a more reliable and secure
connection. The captive screw connector supports balanced and unbalanced audio output.
Balanced audio connections use two signal wires and a ground to minimize interference to audio
signals. Unbalanced audio connections use one signal wire and a ground and are used if other
system components don’t support balanced signals.
Note: Pin outs may vary, please refer to the audio device’s manual to ensure a correct connection.
Important! When terminating cables, please ensure exposed adjacent wires do not touch. This may result in
a short that can damage connected devices.

Category Cable and Connector
For the category cables used in the installation of these products, please be sure to use a 568B
termination as pictured below:
Connector type and size is very important to ensure extenders work correctly. Please use the
matching cable type with the correct RJ45 connector. (e.g. CAT 7 cable should use a CAT 7 connector)
Important! 4K (UHD) signals are sensitive to cable quality and installation technique. It is recommended to
use CAT6a/7 solid core cables for best results.
For convenience, the HD-SC-500 comes with DHCP on. This enables the switcher to be
connected to a network without knowing available IP addresses. If your network does not allow
dynamic IP addresses or if you are using the switcher with a TCP/IP control system, this feature may
be turned off and the IP address set using front panel.
Note: Press and hold the Input button, on the front panel, for 15 seconds to switch between static and DHCP
mode. The Display button will flash. Two button flashes means the unit is in static mode and four button
flashes means the unit is DHCP mode. Static IP configuration will be: 192.168.1.254 - 255.255.255.0

Troubleshooting
1. My HD-SC-500 is losing its static IP address after rebooting.
Please update the unit with the latest firmware.
2. I’m not getting any analog audio after rebooting the unit.
Please update the unit with the latest firmware.
3. The RS-232/IP commands aren’t working for display control.
Please update the HD-SC-500 with the latest firmware. In addition, make sure that the unit
set to the desired control method (e.g., RS-232, TCP/IP). Be sure to include any end-of-line
characters (such as CR, LR, etc.) at the end of the command line.
4. The Auto-Switch feature isn’t working.
Please ensure that Auto-Switching is enabled and that the fallback time is set to at least
10 seconds. Auto-Switching can be enabled through the On-Screen Display, webGUI, or by
using the AutoSW on command. Fallback time can be set using the webGUI or by using the
ASwOutTime command and should be set to at least 10 seconds. If using Mini DisplayPort-
to-HDMI or Mini DisplayPort-to-VGA adapters, make sure that active adapters, which are
compatible with DisplayPort 1.2 or higher, are being used.
5. My Mac computer/device is not passing to a codec or video streaming device or it is slow syncing
to the display.
Set HDCP to “non-compliant.” This setting can be changed through the On-Screen Display,
webGUI, or by using the HDCPSet1 off and HDCPSet2 off commands. The HDCPSet1
command controls the setting for HDMI 1 In and HDCPSet2 controls HDMI In 2.
6. HDCP content (e.g., Blu-Ray, Apple TV) isn’t passing.
Set HDCP to “compliant.” This setting can be changed through the On-Screen Display,
webGUI, or by using the HDCPSet1 on and HDCPSet2 on commands. The HDCPSet1
command controls the setting for HDMI 1 In and HDCPSet2 controls HDMI In 2.
7. My HD-SC-500 is not communicating with my control system, using RS-232.
Verify that the RS-232 captive screw block is securely connected to the RS-232 port on
the HD-SC-500. Make sure that the captive screw block is wired correctly (see page 4)
and that the correct RS-232 settings are being used. The default RS-232 settings for the
HD-SC-500 are: baud rate: 115200, data bits: 8, parity: none, stop bits: 1. To test RS-232,
connect a computer directly to the HD-SC-500 using a USB-to-RS-232 adapter. Once
connected to the computer, launch a terminal program, such as Hercules or hTerm, and
send a command. If RS-232 is functioning properly, then RS-232 feedback will be displayed.
