5 Precautions

5.1 Installation

When installing the COS-100HD, please observe the following precautions.

・ Do not stack or place the COS-100HD directly on top of another COS-100HD

・ Do not block vent holes. To provide adequate ventilation, maintain sufficient clearances around the

COS-100HD (1.2 in. (30 mm) or more)

・ When the COS-100HD needs to be mounted in an enclosed space or an EIA rack without using IDK’s rack

mounting hardware (RM-SF, RM-SH), ensure that a sufficient ventilation/cooling system is provided to

keep the ambient temperature at 104°F (40°C) or lower. If inadequately vented, the product’s service life,

operation, and reliability may be affected.

1.2 in. (30 mm) or more

Bad example

When connecting the COS-100HD to external devices, please observe the following precautions.

・ Read manuals for the external devices.

・ Before connecting cables to the COS-100HD or an external device, dissipate static electricity by touching

grounded metal such as equipment racks before handling signal cables. Failure to observe this precaution

may result in ESD (electrostatic discharge) damage.

・ Power all units off before connecting cables.

・ Be sure to fully seat all plugs and connections and dress cables to reduce stress on connectors.

・ Use the cable lacing bracket to secure a standard HDMI cable as shown.

5.2.2 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.

5.2.3 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.
