Instruction
For installation:
The product is intended to be installed by skilled technicians. For installation, please contact a system integrator or
IDK. Improper installation may lead to the risk of fire, electric shock, injury, or property damage.
Set the power plug in a convenient place to unplug easily.
Unobstructed access to the plug enables unplugging the product in case of any extraordinary failure, abnormal
situation or for easy disconnection during extended periods of non-use.
Insert the power plug into an appropriate outlet completely.
If the plug is partially inserted, arching may cause the connection to overheat, increasing the risk of electrical shock
or fire. Do not use a damaged plug or connect to a damaged outlet.
Clean the power plug regularly.
If the plug is covered in dust, it may increase the risk of firer.

If you continue to use the product under these conditions, it may increase the risk of electrical shock or fire. For
maintenance and repair, contact your IDK representative.
For connection
Instruction
Differences in ground potential among product population of interconnected products and other external devices
may increase the risk of electric shock to personnel or cause damage to the devices or cabling infrastructure. When
using cables to connect devices, including connection of long-distance transmission cables, unplug the power
cables of all interconnected devices.
Power may be restored after all signal/control cables are connected to each device.

5 Connecting to external device
5.1 Preparation
Before connecting to external devices, such as source devices and sink devices, prepare thefollowing cables:
●HDMI cable (19-pin TypeA)
●Coaxial cable (BNC connector)
●Stereo audio cable (RCA pin plug)
●RS-232C cable (D-sub9 pin, female)
5.1.1 Coaxial cable
Use appropriate coaxial cables.
[Table 5.1] Maximum extension distance
Cable type
Maximum extension distance
L-3C2V
131 ft. (40 m)
L-3CFB
262 ft. (80 m)
L-5C2V
197 ft. (60 m)
L-5CFB
361 ft. (110 m)
L-7CFB
492 ft. (150 m)
L-7CHD
689 ft. (210 m)
Notes:
Those distances were obtained under tests using Canare’s cable. If you use other manufactures’cable or a
cable joint (JJ), the distances above are not guaranteed.
If Canare’s L-5CFB and BCJ-J (cable joint) are used together, up to 5 JJs can be used. The total extension
distance may be shortened if a JJ has a problem or impedance mismatch.
The extension distance may be shortened or the number of JJs may be reduced depending on characteristics
of source devices and source devices. The cable length needs to be long enough to avoid those problems.

COS-100HD-B User’s Guide

5.1.2 RS-232C cable
・RS-232C signal (up to 38400 bps) can be transmitted bi-directionally.
・Select cross cables or straight cable depending on devices to be connected.
【See:8.1.2 RS-232C (P.54) 】
5.2 Precautions
Before using the COS-100HD-B, follow the precautions and instructions below.
■Attaching rubber feet
First, clean the bottom surface of the COS-100HD-B as needed, and then peal the release papers from the
rubber feet and place them in each of the four corners.
■Installation
・Before you connecting cables to the COS-100HD-B or an external device, dissipate static electricity
by touching grounded metal such as racks before handling signal cables. Failure to observe this
precaution may result in ESD (electrostatic discharge) damage.
・Do not place the COS-100HD-B on another device directly. The temperature of its bottom surface is
elevated after it is powered on.
・Do not block vent holes. To provide adequate ventilation, maintain sufficient clearances around the
COS-100HD-B (1.18 in. (30 mm) or more).
・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 operation may be affected.
・When you do not use an EIA rack-mount unit, maintain adequate clearances 1.18 in. (30 mm) or
more) as shown below.
1.2 in. (30 mm) or more

■Cabling
Follow the precautions below when connecting the COS-100HD-B to target devices.
・Read the user’s guides of connected devices carefully.
・Power off all devices.
・Be sure to fully seat all plugs and connections and dress cables to reduce stress on connectors.
・Secure the HDMI cable using an attached cable clamp in order to prevent it from falling off this device.

5.3 Application example
Digital video and audio are transmitted from the Blu-ray disc player to the transmitter. The transmitter sends
those signals to the receiver over a coaxial cable, and it also converts digital audio signals to analog and
outputs them to the amplifier. The receiver outputs the received video and audio signals to the projector from
the HDMI output connector.
A control device (e.g. PC) can control peripheral devices (e.g. projector) and data communication between
transmitter and receiver by RS-232C.
