CAT5 Tx BOX

FrontRear

1USB (B type)

Connector for receiving the power supplied from the USB device such as the computer. By connecting a USB cable, you can control the CAT5 Tx BOX using the control commands transmitted over the USB cable.

CAUTION:

We have checked that the power is supplied and the control commands are transmitted properly via the USB connector by connecting it with our computers according to the USB standards.

When the CAT5 Tx BOX is combined with your computer system or USB hub system, check in advance that it operates properly.

2EXTERNAL CONTROL (D-SUB 9-pin)

When the communication via the USB connector is unusable, this connector can be used for RS-232C communication with the control device such as the computer.

NOTE:

RS-232C connection isn’t necessary when the COM port number set by the USB driver is used. Make selection using the input select switch (USB/RS-232C) ( 5 ), as necessary.

3RGB IN (MINI D-SUB 15-pin)

Connector for receiving the analog RGB video signal from the computer.

6CAT5 OUT (Modular connector 8-pin)

Connector for converting and outputting the video signal received by the RGB IN connector ( 3 ) and the control signal transmitted via the USB connector ( 1 ) or the RS-232C connector ( 2 ) to transmit them on the CAT5 long cable.

CAUTION:

Never connect network devices to the CAT5 IN and OUT connectors. If you do so, they may adversely affect with each other, causing breakdown.
