As the PC industry growing, most of the low speed external ports are replaced by USB port. In industrial environment, lots of important equipment still adopt RS-485/422 interface design. With this, most of the users use USB to RS-485/422 converter to transmit the data between PC and RS-485/422 equipment.
CABLE-485-1 is a universal USB to RS-485/422 converter. There is no need external power; it is compatible with USB and RS-485/422 standards. CABLE-485-1 enables to convert USB signal to balanced differential RS-485/422 signal. It provides each wire with surge protection; the tiny interelectrode capacitance ensures high speed transmission for RS-422/485 ports. RS-485/422 adopts DB9 female as connector; internal zero delay auto receiving and transmitting function, 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. All these ensure that it is compatible with all the communication software and interface hardware.
CABLE-485-1 provides connection for point to point, point to multipoint communication. For point to multipoint mode, each converter is allowed to connect 32 sets RS-422 or RS-485 device with baud rate 300-921.6Kbps. The power and data flow indicators show the status of the communication.
