The CV-87R IR over CAT5 Extender boosts up your IR control distance at least 100m (330ft). With single
cost effective CAT-5 cable, users can readily extend and duplicate IR access to IR controllable devices such as
Blue-ray disc players and TV to increase application flexibility. Typical applications include digital signage,
education and demonstration system, and home theater. CV-87R includes two units: transmitting (CV-87R [Tx])
and receiving (CV-87R [Rx]) units. With single 5V power supply, CV-87R can support +12V IR extension cables*.

Dependent upon model
Features
zSupport full bandwidth of IR signal, 20KHz ~ 60KHz
zBuilt-in IR splitter on TX and RX unit
zBi-directional IR path
zSuper long extension distance
zSingle power supply on either TX or RX unit
zEasy to install
zWall mounting housing design for easy and robust installation
The length depends on the characteristics and quality of the cables. Higher resolutions and longer
transmission distances require low skew cables (<25ns/100m) for best performance. Unshielded CAT6
with metal RJ-45 connectors is recommended.

1. There are 2 models for CV-87R: +5V and +12V types. Different IR cables come along with different model and
can NOT be mixed. Any misuse can damage IR cables permanently.
2. The transmission length is largely affected by the type of Cat-5/5e/6 cables. The testing result shows solid
UTP cables (usually in bulk cable 300m/1000ft form) can transmit a lot longer signals than stranded UTP
cables (usually in patch cord form). Shielded STP cables are better suited than unshielded UTP cables. A solid
UTP Cat-5e cable shows longer transmission range than stranded STP Cat-6 cable. For long extension
applications, solid UTP/STP cables are the only viable choice.
3. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
4. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can use
shielded STP cables to improve EMI problems, which is worsen in long transmission.
5. Because the quality of the Cat-5/5e/6 cables has the major effect on how long the transmission limit can
achieve and how good is the received picture quality, the actual transmission range is subject to one’s choice
of Cat-5/5e/6 cables.
