Installation and Basic Operation
Connecting the Multi-Format 5x1 Scaler
HDMI / DisplayPort™ / VGA / Audio
1. Use Gefen HDMI cables to connect sources to the 3 HDMI In ports. Use a
DisplayPort™ 1.2 cable to connect a source to the DisplayPort™ In. Use a VGA cable
to connect a source to the VGA In port.
2. Connect up to 5 un-balanced (single-ended) analog stereo audio sources to Inputs
1 through 5 using the 3-pin Phoenix plugs that came attached to the unit. Follow
channel and polarity markings shown on the scaler’s back panel. Any of these 5 audio
inputs can be linked to any of the 5 video sources and embedded into the HDMI and
HDBaseT™ outputs.
3. Connect a balanced or unbalanced single channel audio source, a microphone with
48V Phantom Power or a non-powered microphone to the Bal-In 3-pin Phoenix
connector. Follow ground and polarity markings shown on the scaler’s back panel. Be
sure to set the 3-position slide switch located to the right of the connector for the correct
operation mode, 48V Mic, (Non-Powered) Mic or Line.
4. Switch between the ve inputs by pressing and releasing one of the input buttons on
the front panel (marked 1 thru 5). The button for the selected input will illuminate. To
activate Auto-Switching, press and hold the Auto button for 3 seconds or longer until
it illuminates. To deactivate, press and hold the Auto button again for 3 seconds or
longer. Press and release the Power button to turn the unit On or Off.
5. Connect a Gefen HDMI cable between the HDMI Out port of the 5x1 Receiver and a
display monitor.
6. If extending AV to a remote display using HDBaseT™, use a CAT-5e cable (shielded
CAT-6A preferred) up to the maximum recommended length for resolution/timing and
color depth and connect between the HDBaseT™ Out port and the HDBaseT™ In port
on the optional Receiver.
CAT-5 / RS-232 / Input Control
1. The RS-232 port can be used to control the scaler and to extend 2-way RS-232
communications between the unit and the optional Receiver over the HDBaseT™
cable. The remote display can be controlled from the source side by an RS-232 control
device, or the Scaler and a connected source can be controlled from the remote
location. To connect an RS-232 device to the Scaler, remove the 3-pin Phoenix plug
that came attached to the unit. Wire Tx, Ground and Rx from an RS-232-enabled
device to the connector, and plug it back into the Scaler. To ensure proper operation,
follow the pin-out of the connector as printed on the unit’s enclosure.
2. The Input Control contact-closure port can be used with up to 5 momentary switches.
Each press and release of the button switches to the assigned input. Each switch can
be connected between the C and the designated connection for each of the 5 inputs.
IR / Audio / IP / Power
1. The IR In/Ext port facilitates IR control of the unit and extends IR from the source
side to the viewing location. Connect a Gefen EXT-RMT-EXTIRN IR Extender module
(available separately) or the IR output of a third-party controller to the IR In/Ext port. If
using an HDBaseT Receiver, connect a Gefen EXT-IREMIT IR Emitter (sold separately)
to the IR Out port of the Receiver and attach it to the IR sensor window of the device to
be controlled.
2. If using an HDBaseT™ Receiver, IR can also be extended from the remote end to the
Scaler side to control the scaler as well as a source. Connect a Gefen EXT-IREMIT IR
Emitter (sold separately) to the IR Out port and attach it to the IR sensor window of
the device to be controlled. Connect a Gefen EXT-RMT-EXTIRN IR Extender or the IR
output of a third-party controller to the IR In/Ext port of the Receiver.

Installation and Basic Operation
3. To use de-embedded audio from the HDMI output with an outboard audio amplier, wire
the Audio Out of the 5x1 Scaler to your amplier.
4. To use the built-in Web Server, Telnet or UDP to control the scaler, connect an Ethernet
cable from your Local Area Network (LAN) to the IP Control port. Use the Gefen
Syner-G™ software to discover and congure IP settings. The default IP address is
192.168.1.72, and the password is ‘admin’ for the Administrator account.
5. To provide power to the Scaler and the HDBaseT™ Receiver (through the link cable),
connect the Scaler’s power supply to its 12V DC jack and to an available electrical
outlet. The Receiver can also be powered locally, but it cannot power the Scaler.
6. The IR remote can be used at the Scaler side or remotely at the Receiver end. It
provides access to Main Volume and Microphone Level controls and the intuitive On
Screen Display (OSD).

HDMI, one DisplayPort™ 1.2, one VGA, ve independently assignable stereo analog audio
and one balanced/unbalanced microphone/line input.
The latter features switchable 48V Phantom Power and Ducking. The ve video inputs,
along with their embedded or assigned audio, can be switched automatically or manually.
Control options include the front panel, hand-held IR remote with On-Screen-Display,
electrical IR, RS-232, IP Control interface, web server interface and contact closure.
The split HDMI and HDBaseT™ outputs feature a scaler, congurable to 3840 x 2160, 30
Hz, 4:4:4. They feed a local and a remote display simultaneously, adding exibility in larger
presentation environments. The Switcher and its recommended Receiver [the EXT-UHDAHBTL-RX, (sold separately)] use Gefen’s implementation of the HDBaseT™ technology to
extend the HDMI output of the Switcher up to 230 feet/70 meters at 1080p Full HD and up
to 130 feet/40 meters at 4K, using one CAT-5e or better cable.
The HDMI and DisplayPort™ inputs support resolutions up to 4K DCI (4096 x 2160) 60
Hz 4:4:4, with HDCP 2.2 and 1.4. The HDMI input and output, and the HDBaseT™ output
support 2 channels of LPCM digital audio. The VGA input supports resolutions up to
WUXGA (1920 x 1200) and 1080p Full HD.
When used with third-party adaptors, the VGA input also supports Component (YPbPr) and
Composite video. The Switcher features an analog L/R audio de-embedder. The optional
Receiver also features analog and digital audio (optical and coaxial) outputs. Any or all
audio outputs can be connected to sound-reinforcement systems at the source side or the
remote end, adding impact and presence to AV presentations.
The 5x1 Switcher features Advanced EDID Management to ensure that sources are
optimized for the displays in use. The Switcher, when used with the optional HDBaseT™
Receiver, provides 2-way RS-232 and IR extension. This facilitates the control of the
Switcher, AV sources placed near the Switcher and the remote display or another device
placed near the Receiver unit.
Industry-standard Power-Over-HDBaseT™ (POH) technology provides power from the
Switcher to the Receiver over the same cable that extends the AV signal. The Switcher
features an integrated IR Sensor on its front panel, as well as an electrical IR input.
If the switcher is mounted in a location where its IR sensor is not within line of sight, a
Gefen EXT-RMT-EXTIRN IR Extender Module or a third-party controller with electrical IR
output can be connected to the IR input on its back panel.
The 5x1 Switcher features a compact form-factor that can be placed on a shelf or securely
mounted on or under a surface. The optional Receiver’s small, ultra-low-prole enclosure
can be securely surface-mounted and conveniently hidden away from sight in the
equipment closet or behind the display. Locking HDMI ports on the Switcher and locking
power jacks on both units ensure long-lasting and reliable connections.
NOTE: Shielded (STP) CAT-5e (or better) cable is recommended. An unshielded (UTP)
CAT-5e (or better) cable may be acceptable depending on cable quality, but isn't the
preferred choice. Care should always be given to keep these cables away from power lines
and other sources of electromagnetic interference.
