1.0 General

Thank you for purchasing the Hall Research HR-733 fiber-optic video
Extender. The HR733 is a 3 input multi-format HD video extender with
bi-directional RS-232 extension and control.

The device can select among 2 HDMI (or DVI) inputs and 1 VGA (or
YPbPr) input and extend the selected source as an uncompressed digital
signal over a single multi-mode fiber to a remote receiver. The device
supports embedded audio on the HDMI inputs, and provides separate R/L
analog or SPDIF (TOSLINK) digital audio inputs for the VGA input.

The HR-733 can also extend a bi-directional data channel (CEC, or RS­232 Serial) over a single multi-mode (OM2 or OM3) fiber optic cable
spanning distances of up to 1000m (3280ft).

The compact remote unit provides an HDMI output (with embedded
audio) for simple AV connectivity to any display.

The RS-232 port can be used as an extension, or at the same time it can be
used to control the Sender (e.g. to select inputs). A user-friendly front
panel with high-contrast alphanumeric LCD enables the user to easily set
up and control the system.

Advanced features include: automatic scaling of the analog video input to
match the native resolution of the remote display, diagnostic messages on
the front panel LCD (e.g. RS-232 strings sent or received), audio delay of
the analog input to correct lip-sync, support for CEC data channel of
HDMI (choice of RS-232 or CEC extension), and 3D deep-color HDMI

1.4 support (without ARC or Ethernet extension).
The Sender unit is designed as a ½ wide 1RU with threaded holes so that

two can be mounted side by side on a tray (Model RMS-1U-1A), or a
single unit can be rack mounted using supplied brackets (pair of F10375).

3.0 Precautions

HDMI, VGA/YPbPr, and Serial over Single Fiber

4.0 Theory of Operation

The Sender provides both digital (HDMI/DVI), and analog (VGA/YPbPr
+ audio) inputs. However, in the fiber video is transmitted as digital
regardless of the selected input, and always comes out as HDMI on the
receiver with audio embedded in the video on the same connector. When
the analog input is selected, its video and audio are digitized and scaled to
match the native resolution of the remotely connected LCD.

The video data is transmitted on only one multi-mode fiber. The reason
multi-mode cable is needed is because the TMDS data are transmitted
over a range of optical wavelengths to reduce bandwidth requirement at
any particular wavelength. The TMDS signals use LED lasers to drive the
cable. However, for safety reasons, these lasers are not turned on if no
fiber optic cable is plugged in at both the Sender and Receiver.

Additional (non-video) DVI or HDMI signals are also seamlessly
connected between the source and the sink device. These include:

 DDC Channel (SDAT and SCLK) for EDID and HDCP
 Hot Plug Detect (to detect remote monitor connection)
 Source Active +5vDDC (to indicate to sink there is a source)

In addition, the fiber-optic link provides a general purpose bi-directional
data lane that can be assigned by the user to be used as RS-232 pass­through between sender and receiver, or to extend the CEC standard of the
HDMI. Currently CEC is seldom used in pro-AV installations, and its
implementation varies from one TV manufacturer to another, so as default
the HR-733 uses the data lane for RS-232 communication and control.
However, the CEC can be selected by the user, in which case the RS-232
port on the remote unit will not serve any function (the RS-232 port on the
Sender can still be used for source selection).

5.0 Installation

5.1 Required Cables

 1 or 2 HDMI cables to connect up to 2 HDMI sources to the HR-

733-S

 HDMI cable to connect the HR-733-R to the HDMI display
 HD-15 male-to-male VGA cable to connect a PC analog video or

an HD-15 to 3-RCA for component YPbPr DVD video
connection to the HR-733-S

 3.5mm stereo audio cable or optical (TOSLINK) audio cable to

connect associated audio of VGA/YPbPr source to the sender

 RS-232 DB9 male-to-female (pin to pin) cable to connect the

HR-733-S’s serial port to a PC

 Multi-mode (MM) fiber-optic cable to connect the HR-733-S and

HR-733-R

5.2 Inputs & Outputs

The HR-733-S has 2 HDMI inputs, 1 VGA/YPbPr input with audio, and a
bi-directional RS232 port. The audio source of the VGA/YPbPr input can
be either 3.5mm L/R stereo or optical.

The HR-733-R has l HDMI output and 1 bi-directional RS232 port.

5.3 Fiber Optic Cable Requirements

Each end of the HR-733 uses a single SC connector and requires a multi­mode fiber-optic cable. Unlike some other fiber-optic equipment that may
work with either single-mode or multi-mode cables,
the HR-733 is not compatible with single-mode
cables. Multi-mode cables are generally available in
OM1, OM2, or OM3 constructions. The OM3
cables are best suited for max transmission lengths
and are recommended for this product.
