Parts Name and Functions (continued)
CAT5 Tx BOX
1
USB (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.
2
EXTERNAL 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.
3
RGB IN (MINI D-SUB 15-pin)
Connector for receiving the analog RGB video signal from the
computer.
4
RGB OUT (MINI D-SUB 15-pin)
Video connector for buffering and outputting the analog RGB
video signal received by the RGB IN connector (
3
).
5
Input select switch (USB/RS-232C)
Switches the control input between the USB connector and the
RS-232C connector.
6
CAT5 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.
7
Composite sync signal level switch
Switches the composite sync signal level.
The TTL level and the 0.3 V level are switched.
8
Auxiliary power supply input connector (DC IN
5 V)
Though the power is supplied from the above-mentioned
USB connector, an auxiliary DC power adapter (commercially
available) is also available. When +5 V (according to the product
specifi cations) is supplied from the above-mentioned DC power
adapter, the power supply is automatically switched from the
USB connector. (You cannot use both at the same time.)
CAUTION:
• Don’t apply a voltage out of the specifi ed range to the
auxiliary power supply input connector or connect it with
incorrect polarity. If you do so, the connected devices may
be overheated or damaged.
• The auxiliary power supply input connector isn’t intended
for general use. Commercial DC power connectors are
available in different shapes. When you want to use this
connector, consult a qualifi ed electrician or your dealer in
advance.
Power connector type: DC jack R/A type (Diameter of the
