DAM-3230NP/NF
DAM-3230NF and DAM-3230NP are universal USB to RS485/RS422/RS232 plug-in photoelectric isolation converters, compatible with USB1.1\USB2.0, and support RS422, RS485 and RS232 standards. The converter has zero-delay automatic sending and receiving conversion inside, and the unique I/O circuit automatically controls the direction of data flow. Full-duplex (RS-422), half-duplex (RS-485) mode conversion is realized through jumper setting, just plug and play, to fit all existing communication software and interface hardware. DAM-3230NF and DAM-3230NP use photoelectric isolation, special DC/DC module and RS-422/RS-485 to provide 600W lightning protection, surge protection, +/-15KV ESD protection per line and prevent common ground interference. DAM-3230NF and DAM-3230NP can be applied between the main control machine, between the main control machine and external devices, forming a point-to-point, point-to-multipoint remote multi-machine RS485/RS422 communication network, connecting up to 32 RS485/RS422 devices to realize multi-machine response communication. Drivers for USB support various operating systems.
