AC Powered RS-232 to RS-485/RS-422 Converter (Commercial Level)

Name:AC Powered RS-232 to RS-485/RS-422 Converter (Commercial Level)

PA 2108B is a multifunctional converter with external power supply, it compatible with RS-232/RS-485/RS-422 standard. It can change the single-ended RS-232 signal to balanced RS-485/RS-422 signal, RS-232 interface use the DB9 female connector connect with the serial of computer ,on the other side RS-485/RS-422 use the DB9 male connect with 6 terminal board, Or you can choose the RJ-45 port connect with the device which has the RJ-45 connector . Since the RS-485 support two wire half duplex, which means the RS-485 only have two lines to receive data and send data. Handshaking signal usually control the direction of data sending, the inner circuit of converter is able to auto sensing the direction of data flow, and switch to ENABLE CONTROLS automatic. A RS-485 network can be built convenient without any handshaking signal; the RS-485 ENABLE CONTROLS is full transparent, no need to modify any software for the old working method based on RS-232. it is mainly used for the field of electricity, industrial automatic control, IC card billing system and time attendance, one card solution, access control system, parking system, and so on.
