1) Summarize
ATC-108 light insulation type converter, compatible RS-232C,RS-422, RS-485 standard. AT-108 can transform RS-232 signal into RS-422 OR RS-485 signal in balance difference. Inner light insulation type and DC/DC direct current converter, can provide 3500V isolation voltage, Fast instantaneous voltage suppresser (TVS) can control lighting and ESD effectually, provide 600W protect power against lightning strike surge for each line, which prevent lighting strike and grounding interfere effectually. RS-232 port connect with PC?IPC?or laptop by a DB9 linker, RS-422, RS-485 port connect by connection terminal with 7 bit connection. Because RS-485 sustain two line half double work, i.e. RS-485 only two lines which must send and receive massage. Handclasp single (for example RTC, Request to send) usually control TXD direction,ATC-108 light insulation joint converter inner circuit can automatically apperceive data stream direction and automatically switch so that control. It is convenient consist RS-485 network without handclasp single. RS-485 control is complete transparent without any modify based on RS-232.
ATC-108 light insulation port converter can provide dependable connect from spot to spot, spot to more spot which can permit connect 32 equipment for RS-422 or RS-485. Data communication speed 0-115.2 KBPS, three power and data flux indicator light can show failure situation. Supporting communication format from RS232C to RS-422, from RS-232 to RS-485 transform.

4) Installation equipment and application
Please consult the reference book before installing ATC-108 light insulation converter. Connect communication cable with RS-232,Joint port, power converter connect with +9V insert port, one point connect with RS-422 or RS-485 equipment according to DB9 pin. Because ATC-108 converter inner converter method adopt auto-suit design, user dont have to modify any setting when finish RS-232 to RS422/485 conversion. Connect directly equipment according to RS-422/485 joint definition.
ATC-108 converter can hold the four-communication format as following:
1. Dot to dot/ four line full duplex
2. Dot to more dots/ four line full duplex
3. Dot to dot/ two line semiduplex
4. Dot to more dots / two line semiduplex
5) Power and surge protection grounding
1.External power
ATC-108 light insulation joint converter, adopt 9V power adapter power supply, also power supply from other direct current power or equipment power supply, power voltage +9---+12V, electrical current 300mA,
2.Surge protection grounding
Ordinary port converter without many protection equipments, because instantaneous high voltage on joint data line, try to release energy to ground wire from mini resistance of equipment. So it is convenient to damage joint parts of an apparatus. ATC108 light insulation converter can provide 600W lighting strike protection power, fast instantaneous voltage suppresser (TVS) can control lighting and ESD effectively, ATC-108 joint converter DB9 pin PIN5 is surge protection grounding. User should provide reliable grounding for protecting communication safety.
6)Failure and elimination
1. Data communications failure
A. Check RS-232 connect rightly or not
B. Check RS-422 joint connect rightly or not
C. Check RS-485 joint connect rightly or not
D. Check power supply voltage and polarity is right or not
E. Check equipment joint type and joint converter whether or not in right conversion mode.
2. Data lose or failure
A. Check data communication equipments two-end data speed, whether format is consistent or not.
