1Product outline
MSD-804FD (hereafter referred to as “the MSD”) is a presentation switcher having a built-in scan converter.
For video output, 8 digital inputs are mounted, and HDMI and DVI signals are supported. Input video signal is
converted up to QWXGA or 1080p and HDMI/DVI signal can be output. HDBaseT output (Cat6 output) is
prepared as an optional extra. When the HDBaseT output is mounted, signal is output to HDMI and HDBaseT.
For audio input, 8 digital and 8 analog inputs are mounted, and selected audio signal is output to digital audio
(HDMI) and analog audio. Audio level of each input and each output can be set separately. The MSD also has
the Lip Sync function to correct gaps between video and audio signals.
The MSD has RS-232C (2 ports) and LAN as communication ports for external control, which enables remote
operation of settings. External devices that are connected to the MSD from RS-232C, LAN, or CEC can be
controlled through RS-232C, LAN, or HDBaseT output by registering control commands. For control
commands, the wait function is available to switch the contact after cooling-down time passes for power
control of projectors and other devices.
You can execute control commands using front panel keys, RS-232C, and LAN, and you can also execute
them when operating the input switching keys and turning on the MSD.

*1 The anti-snow function automatically fixes snowy noise that is a specific symptom of HDCP-compliant
signals and mainly occurs at start-up. This feature does not work when snowy noise has already been
occurred during startup or when it occurs due to bad condition of the transmission line.
*2 The display device needs to support CEC to enable this function. Some display devices cannot be
controlled by CEC.
*3 For digital systems, some problems, such as an HDCP authentication error, can be recovered by
physically disconnecting and reconnecting the digital cables. However, the Connection Reset function
will fix these problems automatically without the need to physically plug and unplug the cables, by
creating the same condition as if the cable were physically disconnected and reconnected. This
function works only for the MSD’s output.

*The HDMI I/O connectors support HDCP (High-bandwidth Digital Content Protection), which is a copy
protection technique developed by Intel. If DVDs or other contents with copyright protection are played,
both source devices (such as DVD players connected to input connectors) and display devices
(connected to output connectors) are required to be HDCP compliant.

5Installation
Since the MSD has various types of I/O connectors, make sure that shapes of the cables and connectors
match when connecting cables. If you try to connect them forcibly to an unmatched cable and connector, they
might be damaged. If turning on the MSD in that situation, the MSD and display devices may be damaged. Be
sure to plug cables completely and install them without any stress on the cables.
5.1 Connecting digital input/output devices
For digital input, HDMI connector is used while HDMI connecter and RJ-45 connector are employed for digital
output. These connectors can input/output HDMI signals and DVI signals.
HDBaseT output: connected to IDK’s twisted pair cable receiver (HDC series) and can be extended up to 328
ft. approx. (100 m).

[Fig.5.1] Connecting digital devices
For digital I/O, the MSD has the cable equalizing circuit (for output, only OUT A) to correct distorted signals
when a long cable is connected. The amount of equalization for the input side is set automatically, but do set
the amount for the output side using the following menu settings: “7.7.1 Output equalizer [OUTPUT
EQUALIZER]”
[Table 5.1] Maximum extension distance
Digital input
Up to 32.8 ft. to 98.4 ft. approx. (10 m to 30 m)*
Digital output
32.8 ft. to 164 ft. approx. (10 to 50 m)*
*Extension distance depends on the connected I/O devices. The range mentioned above is the
maximum extension range acquired when IDK’s AWG24 cable is used and signals of 1080p 60 Hz, 24
bit/pixel (8bit/component) is input or output. For some I/O combinations, and if you use cables of other
manufacturer, video may be disturbed or may not be output even if signals are within the range
mentioned above.

If connecting to HDBaseT output (RJ-45 connector), follow the following notes. If the transmission line has a
problem, video and audio may be interrupted.
Connectors for a long-distance transmission are the same as eight-core modular connector that is used in
Ethernet. However, since the transmission method is not the same, it cannot be connected to Ethernet.
To ensure the best performance, select the appropriate cable and connect it correctly.
1. We recommend a Cat5e/Cat6 UTP/STP cable for the twisted pair cable.
2. For pin assignments, apply T568A or T568B standards for straight through wiring.
3. Keep the twisted pair cable as straight as you can. If you coil the cable, it is easily affected by noise.
4. Do not place this product in an electrically noisy environment, since high-speed signal is transmitted
5. If the distance between the transmitter and receiver is 100 m/328.08 feet or less, cables can be joined
using an RJ-45 plug coupler or wall outlet.
6. For transmission longer than 164 ft. (50 m), Cat6 cable is recommended.
If the problem still cannot be solved, shorten the length of the twisted pair cable. Problems may be solved by
the action.
Note: HDBaseT output does not support DVI signals whose content is protected by HDCP. If you need to
extend DVI signal with HDCP, please use the IDK’s HDC-RD100 as a receiver.
For HDMI I/O, please use the cable with HDMI Type A (male) connector. For cables longer than 16.4 ft. (5 m),
use our recommended cable, AWG24*.
*AWG(American Wire Gauge)
Recommended cables:
Flexible model Standard model
10 m ：HDSS-10 HDMI/HDMI24-10
15 m ：HDSS-15 HDMI/HDMI24-15
20 m ：HDSS-20 HDMI/HDMI24-20
30 m ：- HDMI/HDMI24-30
40 m ：- HDMI/HDMI24-40
50 m ：- HDMI/HDMI24-50
Notes:
If you use a cable other than the recommended cable above, the extension distance may be shorten.
Those model number would be changed. Please contact us.

The HDMI cable does not have lock mechanism, but the provided cable clamp prevents the cable from falling
off.

■Attaching cable clamp
1. Remove the ring from the clamp and pass it through the clamp as indicated below.
2. Plug the clamp bar into the hole of the main unit.
