1‑2.General information
The products, KE 0202CT2W (w-type)/KE 0101CR-BW, are a transmitter and receiver for
long distance transmission of a wide band signal such as a computer, high definition TV or a
composite signal through a twisted pair cable (CAT5 e or CAT6).
They also have the function of long distance transmission of stereo sound and RS232C
serial data.
The minimum recommended transmission range is 10m(32.8ft). The maximum recommended
transmission range depends on the refresh rate and resolution. The transmission range
(when using our recommended cable) is as follows.
Recommended cable : OKTP-E5-P-AWG24x4P
(OKANO ELECTRIC WIRE CO.,LTD)

2. Connection
2‑1.The cautions and warnings.
◆Cautions
・ Use the recommended cable for this product for best results.
(OKANO ELECTRIC WIRE CO.,LTD: OKTP-E5-P-AWG 24x4P)
When a cable other than the recommended cable is used, make sure that the characterisitcs
and functionality of the cable is fully understood before use.
・When cable length is longer than the recommendation distance indicated in the
"product outline", quality of the image may deteriorate.Please note that use beyond
the recommended distance will require outside support.
・If a twisted-pair cable is laid near a power supply line with a lot of noise,
the image may flicker. In this case, run the twisted-pair cable away from the power supply
line.
・If the product is connected to an AC power supply with noise, the image may flicker.
In this case, use an AC wall socket type noise filter.
・Use the cable mounting kits, when weight will be applied to the twisted pair connectors of the
transmitter. (Please refer to "2-3. Cable mounting kit (Twisted pair transmitter)").
◆Warnings
・Do not connect any unauthorized product to the extension input/output connectors of the
twisted pair transmitter or receiver, as it can cause damage to the products.
Kowa is not responsible for any damage or injury caused as a result of improper use.
・Turn off the transmitter, receiver, and any product that is connected to the devices when
removing or installing twisted pair cables. Failure to do so can cause damage or failure
of the products.
