3¡¢RS485/232 Converter£¨in our website product name: ATC108£©  
The company is equipped with RS485/R232 converter model ATC-108, the outline:

¢Ù¡¢ATC-108 are optical isolated interface converter is compatible with RS -232C, RS-422, RS-485 standard, the ability to single-ended RS-232 signals are converted to a balanced differential RS-232 or RS-485 signal, the built-in optical isolators and DC / DC DC converter, able to provide 3500V isolation voltage, fast transient voltage suppressor (TVS) can effectively suppress lightning and ESD, provide each line of the lightning surge protection power of 1000W to be effective in the to prevent lightning strikes, and a total of interruption

¢Ú¡¢RS-232 interface port via a standard DB9 female head and PC, laptop computer connections, RS-232, RS-485 terminal through the convenience of the seven terminals with a plug connection.

¢Û¡¢ATC-108 optical isolation interface converter internal circuitry to automatically sense the direction of data flow and automatically switch to enable to control, to facilitate the composition of an RS-485 network without the need for any handshake signal, this RS-485 enable control is completely transparent, without losing the previous work based on the RS-232 to make any software modifications.

¢Ü¡¢ATC-108 optical isolation interface converter for point to point, multipoint communication to provide reliable connectivity, multipoint allows connect up to 32 RS-232 or RS-485 interface devices, data communication speed from 0 -115.2KBPS, three power supply and data traffic lights may direct fault conditions, the support means of communication with RS -232C to RS-422, RS-422 to RS-485 converter.
