Introduction
The dual HDMI and VGA switcher w/scaler provides a multisystem solution. Use the HD-SC-500
as: a standalone 3 in 1 out switcher for small systems, an analog to digital video converter for
systems with no VGA ports, and a scaler for systems with displays that require specific resolutions.
Supports scaling of video up to 1920x1200/1080p, VGA conversion and audio embedding and de-
embedding, the HD-SC-500 has a function in almost any system.

Tip (+)
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.
Important! With unbalanced connections a jumper is needed between ground and negative to reduce noise
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.

A login screen will appear (this is the same log in for admin and general users). For the first log in (and future
admin changes) the username is “root” and password is “Atlona”.
Note: Only the admin password can be changed (see page 15). The username will always remain “root”.
Network Connections
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 is not compatible with
dynamic IP addresses or if you are using the switcher with a TCP/IP control system, DHCP may be
turned off and the IP address set using RS-232 commands or the webGUI.
WebGUI
Atlona has created an easy to use webGUI for initial setup and later changes to the configuration of
the HD-SC-500.
To begin, plug a LAN cable into the LAN port of the HD-SC-500 and the network switch, then type
the IP address of the unit into a web browser of a PC connected to the same network (as seen below).
To find the switcher IP: Select “Information” within the OSD menu or use RS-232 command
“IPCFG”.
Important: If any stability issues are experienced, disable any anti-virus or firewall that may interfere with
network communication to the switcher. Once set up is done and the switcher webGUI is no
longer being used, the firewall and anti-virus can be re-enabled.
The Info screen displays general system information.

The EDID Page enables the preferred input timing to be selected and HDCP compliance reporting to
be set.
HDMI Prefer Timing: Select the best resolution to ensure compatibility with the input & output
VGA Prefer Timing: Select the best resolution to ensure compatibility with the input & output
HDMI 1 HDCP: Switch the HDCP reporting between compliant or non-compliant
HDMI 2 HDCP: Switch the HDCP reporting between compliant or non-compliant
The HD-SC-500 has two HDCP reporting modes: compliant and non-compliant.
Note: HD-SC-500 does not alter the signal in any way
Note: HD-SC-500 will not pass HDCP compliant content to a non-HDCP display
Compliant -
Reports to the source it is connected to an HDCP compliant device
Note: Will pass all HDCP compliant and non-compliant source signals to an HDCP compliant display
Non-Compliant -
Reports to the source it is connected to an HDCP non-compliant device
Note: Some Apple products (and other PCs) will encrypt non-HDCP content, stopping non-HDCP compliant
displays from receiving even personal files such as: PowerPoint, Excel, or Word files. Use this mode to
pass non-HDCP content (e.g. to codecs or video streaming devices)
Note: Blu-Ray content, Apple TV, and other HDCP compliant source signals will not pass when set to
non-compliant
