UTEK UT-203A | RS232 to RS485 & RS232 to RS422 Converter Adapter Price in Pakistan

For communication between PC with different standard serial port and external equipments or intelligent instruments, standard serial conversion is necessary. This converter is compatible with RS-232C, RS-485/422 standards. It converts RS-232 signals into balanced differential RS-485 or RS-422 signals. The transmission distance of RS-232 communication can be extended to 1.2km. 

It adopts unique “RS-232” charge pump technology to drive the system, and gains power without initializing RS-232 serial port. This converter is with built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTS, DTR); there is no need jumper wire setting for full duplex (RS-422) and half duplex (RS-485) mode, plug & play. 

Introduction:

• Mini size, DB9 connector, with terminal block
• Standards: RS-232, RS-485, RS-422 TIA/EIA
• Automatic traffic direction control, no need for external flow control signal (RTS)
• Power: port-powered, no need external power connected & serial port initialization, real TXD/RXD/GND communication
• Allows connecting 32 sets networking device
• Transmission distance: 1,200m
• Baud rate: 300ps-115.2kbps
• Transmission media: twisted-pair or shielded cable
• Working mode: asynchronous half-duplex (RS-485) or full-duplex (RS-422), without jumper setting
• Works with all communication software, plug & play
• Dimension: 63×33×17mm
• Operating temperature: -25℃ to 70℃
• Humidity: 5% to 95%
• Supports all operating systems

It is compatible with current communication software and hardware, no need to set the previous working mode which base on RS-232. This guarantees that there is no need to modify the programming under RS-232 full duplex or half duplex mode; it will run smoothly under current software and hardware. 

The transmission rate is 300-115.2kbps. It can be used between hosts, host and SCM, which building a point to point, point to multipoint long-distance communication networking. It is widely applied in industrial automation control system, all-in-one card, access control system, parking system, ATM system, bus charging system, canteen ticketing system, attendance system, and toll station system, etc.
