rs232 isolator


rs232 optical isolator

RS-485 Isolator
DB9 female connectors
Interface feature: RS-232C, RS485/RS-422 standard interface compatible with EIA, TIA

UT-242E is RS-232 to RS-485 converter. In order to carry through remote digital communication between computers and various standard series interfaces converter facilities or intelligent instruments, it needs inter exchange of standard series interface converter of compatible RS-232C, RS-485 and RS-422 standard is able to convert mono-end RS-232 signal to balance difference RS-485 or RS-422 signal and extend the communication distance to 1.2km. No external power but adopts a particular RS-232 charge pump to drive the system, and gains electricity without initializing the RS-232 series interface. An internal zero-delay auto transceiver and particular I/O circuit automatically control the data stream direction instead of an handshake signal (for example RTS, DTR etc).There by to guarantee the function under RS-422 without changing the program compiled under RS-232 Full-duplex and RS-485 Half-duplex mode and assure the adaptation to current operation software and interface hardware. The transmission rate of 300-115.2kbps is capable of applying between host computers, host computer and is extensions or external equipment and forms point-to-point, point-to-multipoint remote and multi-communication network.



UT-242E implements multi-machine response communication and commonly used in systems of industrial automation control all-one-card, door safe, car parking, ATM, bus charge, eatery sell out, staff attendance management, and toll highway etc.
