6 Precautions
Before connecting to external devices, follow the precautions below.
6.1 Installation
When installing the HDC, please observe the following precautions.
・Do not place the HDC on top of another HDC.
・Do not block vent holes. Please secure the space above ambient 30 mm/1.18 inches.
・Do not install the HDC to an enclosed space. When the HDC needs to be installed to EIA rack mount or
an enclosed space, please 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.

HDC-RH401/201/101 Users Guide
18
6.2 Cabling
When connecting the HDC to the external devices, please observe the following precautions.
・Read manuals of the external devices.
・Before you connect the cable to the HDC or an external device, please remove electrification of the body
by touching the metal around that is grounded.
・Turn off all devises’ power before connecting the cable.
・Be sure to plug cables completely and install them without any stress on connectors.
・Fix HDMI cables using cable clamps to prevent those cables from falling off.

6.2.1 Cables
IDK Corporation provides various digital cables such as HDMI, DVI, and twisted pair cables.
Please choose appropriate cables for your system configuration. For analog audio and RS-232C, please use
on processing the cable to fit the connectors.
6.2.2 Twisted pair cable
When connecting twisted pair cables to the HDC, please observe the following precautions.
・Cat5e/Cat6 UTP/STP can be used, however, we recommend a CAT.5E HDC cable* for the twisted pair
cable which is developed by IDK to maximize quality of video transmission.
・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.
・The shielded STP cables are less affected by interference or external noise than UTP cables.
・The connector for twisted pair cable is as same as the connectors which are used for Ethernet (8 core
modular type connector), however, it cannot be connected and use for Ethernet because the way of data
transmission is different.
・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.
・Following table shows extension distance by each twisted pair cable. The extension distance depending
on installation environment.

* CAT.5E HDC cable developed by IDK Corporation is double shielded twisted pair cable for high quality video
transmission. It protects video signal from external noise or other interferences by having double shielded
structure. Its transmission characteristic meets 500 MHz up to 100 m/328.08 ft., and it is certified and
recommended by HDBaseT alliance.
