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 five 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.
