2 Product outline
MSD-501/502/701/702 (hereafter referred to as “the MSD”) is a presentation switcher having a built-in scan
converter.
For video output, the following signals are supported: HDMI, DVI, composite video, S video, analog RGB, and
analog YPbPr. Input video signal is converted up to QWXGA or 1080p and divided into two outputs:
HDMI/DVI signal and HDBaseT signal.
For audio input, both digital and analog signals are supported and those signals can be converted each other.
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 signal.
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 can be controlled through RS-232C,
LAN, and CEC 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.
HDBaseT signal support bidirectional communications of RS-232C and LAN.

■Analog video input connector
D-sub15 pin connector is used and enables not only analog RGB signal (such as PC) to be input, but also
analog YPbPr (SDTV/HDTV), composite video (NTSC/PAL), and S-video (NTSC/PAL) signal to be input
using a conversion cable.

5.2 Preparation
Prepare the following cables before connecting to external devices, such as source and sink devices.
・HDMI cable (Type A (19 pin))
・DVI cable
・Twisted pair cable
・Stereo audio cable (RCA pin)
■HDMI cable
[Conversion cable]
For when the external device has a DVI connector:
[Fig. 5.3] Conversion cable (HDMI-DVI conversion)
[Long cable]
For when a 5 m/16.4 ft. cable is used for I/O cable:
[Fig. 5.4] HDMI long cable (Flexible model)

MSD-501/502/701/702 User’s Guide
19
■DVI cable
For DVI input, use a DVI-I or DVI-D (male) cable.
For when a 5 m/16.4 ft. or longer cable is used:
[Fig. 5.5] Single-link long cable
Note: Since DVI signal is very fast, use a cable meeting DVI Rev1.0 standard.
■Analog video input conversion cable
If inputting analog YPbPr signal or composite video signal, use “CC-01”, analog video input conversion cable.
[Fig. 5.6] Analog video input conversion cable: CC-01

5.3 Precautions
Before connecting to external devices, follow the precautions below.
■Installation
●Do not place the MSD on top of another MSD.
●Do not block vent holes. Please secure the space above ambient 30 mm/1.18 inches.
●Prepare ventilating equipment to keep the ambient temperature at 40 degrees C/104 degrees F or less. If
inadequately vented, the life of parts may be shortened and operations may be affected.
■Twisted pair cable
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.
●We recommend a Cat6 UTP/STP cable for the twisted pair cable.
●If using an STP cable, connect the FG connector to an earth ground source. Otherwise, the shielding
feature does not work correctly. When using a UTP cable, we still recommend using the ground
connector.
●For 50 m/164.04 ft. or shorter transmissions, Cat5e UTP cable can be used.
●The shielded STP cables are less affected by interference or external noise than UTP cables.
●The maximum extension distance of Cat5e/Cat6 UTP/STP cable is the shorter maximum extension
distance of the connected HDC receiver and sink device.
●For pin assignments, apply T568A or T568B standards for straight through wiring.
●Do not give connection cables a strong pull. The allowable tension of the twisted pair cable is 110 N.
●Do not bend the connection cable at a sharp angle. Keep the bend radius four times of the cable diameter
or longer.
●Do not tie the cable tightly; leave a space allowing the cable to move slightly.
●If you use the same cables, we recommended keeping a distance between the cables or not to place
the cables closely in parallel.
●Keep the twisted pair cable as straight as you can. If you coil the cable, it is easily affected by noise.
●Do not place this product in an electrically noisy environment, since high-speed signal is transmitted.
Particularly when you use a high-output radio around this device, video or audio may be interrupted.
●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. Up to two cable couplers are allowed. Couplers supporting
Cat6A (10GBase-T) are recommended.
Note: If there is a problem in the transmission path, video or audio may be interrupted. Please check the
items above. If the problem still cannot be solved, shorten the length of the twisted pair cable.
