Port powered or external powered design Isolation of power and communication ports Automatic detection of communication baud rate Automatic control of transceiver direction Easy to use plug and play device (no configuration software required) CE / UL certification RS232/CMOS to RS422/RS485 Converter converts RS232/CMOS lines to balanced RS422 or RS485 signals. RS232/CMOS to RS422/RS485 converter is available in two models, CNV-01and CNV-02-B. Power is isolated from communication ports in the CNV-01 model, whereas communication ports are not isolated. The converter is port-powered (line-powered: RXD+RTS+CTS) or externally powered. In case of point-to-point communication and if the cable length is less than or equal to 2 meters. On the RS232 side, then the external power supply is not needed. This unit takes less than 4mA to operate plus load current. For applications that require a large load current, an external +24VDC power supply on the terminal strip is required. (NOTE: CMOS signals are not available with the CNV-01 model) Both the communication ports as well as power are isolated in the CNV-02-B model. This model operates on an external 24VDC supply. The unit has a DB9 female connector on RS232/CMOS side and PBT on RS422/RS485 side. RS485 port has a 4-wire with signal ground system and can also be made as a 2-wire RS232-RS485 converter with the signal ground system.
