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.
Features
:
*RS-232 interface converted to RS-485 interface for long distance connection. *Automatically switching Transmitting and Receiving *LED is to show communication status *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.
Specifications
:
*Communication: Half-duplex,1 start bit,8data bits, no parity Baud rate 9600/19200 selectable. Power Supply: DC9~12V,300mA Dimensions: 69*53*22mm RS-232 Interface Connector: D-sub 25 pins female connector RS-485 Interface Connector: Screw type terminal block 4 pins Environment: Operating Temp: 0~55 Deg. C Storage Temp: -10~55 Deg. C Humidity:10~90% relative
Note: The Specification is subject to change without notice.
Application
:
PC to PC communication PC to terminal devices Any long distance connection
Available versions
:
CON485:for TR550 with RS-485 connection CON485:for TR510 with RS-485 connection CON422/485:for AC9100 with RS-485 CON422/485;for TR52X/TR534 with RS-422
Remark
:
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.
