IT-3000-OCT
Industrial isolation
RS-485/422 Bus Division Switch
Introduction:
IT-3000-OCT is a type of RS-485/422 bus division concentrator of
high performance. IT-3000-OCT adopts the unique equipotential
differential isolation and bus division concentration technology to
effectively such problems as ground potential difference, impedance
matching and lightning strike frequently seen in engineering wiring
process. Users can easily optimize the RS-485/RS-422 bus structure,
divide the network section and improve the communication
reliability.
The fault network section shall be isolated in case of lightning strike
or equipment faults to ensure the high communication reliability of
other network sections. Such performance of IT-3000-OCT can
significantly improve the reliability of existing RS-485/RS-422
network, and effectively shorten the network maintenance time.
Reasonable utilization of IT-3000-OCT can enable you to design
unique RS-485/RS-422 system.

6. Support stage connection, each port support 256 nodes loopback
7. Data direction auto-turnaround, no flow control is necessary
Pinout Configuration:
1.The product front panel sketch map:
IT-3000-OCT panel have 10 LED indicator，Used for indicate power
state (PWR), Up-Stream port working state (up), Down-Stream port
working state (1 to 8)
PWR lamp light when powered (220VAC power supply).
When RS-485communication, up lamp flash when Up-Stream port
TXD, opposite state lamp flash when Down port TXD.
When RS-422 communication, Up-Stream port and Down-Stream
port TXD at the same time, up state lamp and opposite Down-Stream
port lamp flash.
2. The product back panel sketch map:
IT-3000-OCT is make up of 1 Up-Stream port and 8 Down-Stream
port. You can require the port quantity according to your needs.

IT-3000-OCT FAQ:
1. LED indicator instruction
1. PWR Power supply indicator，Red
2. UP Up-Stream port transfer data, LED Flash
3. 1-8 Down-Stream port receive data, LED Flash
2. LED indicator OFF
1. Power supply cable turnoff
2. Insert power supply failed
3. Choice incorrect Power supply
3. Equipment examine automatic
1. When interface connectionless, insert the power supply, PWR,
UP indicator light, and Down-Stream port state indicator(1-8) light,
the quantity of the lighting LED is up to the availability of the
Down-Stream quantity.
2. If the t is RS-232, Down-Stream port is RS-422, connect the
Up-Stream port to PC RS-232 port correctly, Using “Start”→
“accessory” →“communication”, open the typical terminal, choice
the correct COM port and 9600bps speed, shorting the down
RS-422 port, input the character in the typical terminal window,
you will see the data indicate.
3. Meanwhile, the Up-Stream TXD indicator correspond to
Down-Stream RXD flash, then the interface communicate
normally.
Using this method, you can test all the Up-Stream port
correspond to Down-Stream port working normally or not.
Note: The Loop-back testing just used for full-duplex
communication, is not suitable for the RS-485 communication.
4. Communication failure
1. Use incorrect power supply
2. Insert power supply failure
3. The connection sequence incorrect
4. Oppositive use up strem port and Down-Stream
5. Down-Stream port connection incorrect
6. Exceed the loading and transmit distance
7. Using incorrect transfer media
8. RS485/422 connection incorrect
