Catalog     Picture  


RS-232 interface is a standard communication port in PC and other control system. And it is a very popular communication interface in control system, building access control system (AC9100), office automation system, time record system (TR510) barcode system,pos system.....etc .However,RS-232 has many limitations in transmission speed and distance ,So it can not be flexibly used in high speed and long distance control system. Now we support RS422/485 inter-face  converter for RS-232 communication system. You don't need to change any specification of your system.


*RS-232 interface converted to RS-485 interface for long distance connection.
*Automatically switching Transmitting and Receiving

*Baud rate selectable 9600 or 19200
*one converter supports up to 255 terminal devices.
*Communication distance up to 1000 meters (must be AWG #24, #22 , #18..... individually shielded multiple pair cable)
*Don't need to change any specification of your existing systems
*Your software with RS-232 protocol still  can be used.

CON422/485;for TR52X/TR534 with RS-422


1.CON485 is an RS-232 to RS-485 smart converter so that you don't need to change any specification of your existing systems, and your software which is with RS-232 protocol still can be used as well.

2.CON422/485 is RS-422/485 mode selectable. Select RS-422 for RS-232 to RS-422 converter and your software which is with RS-232 protocol still can be used without any change. Or select RS-485 for RS-232 to RS-485 converter but your software must be with RS-485 communication protocol.
