Black Box Async RS232 to RS422/485 Interface Converter - DB9 to Terminal Block

The BLACK BOX® Universal RS-232 to RS-422/485 Converter with Opto-Isolation isolates and converts RS-232 signals into RS-422/RS-485 signals and vice versa. Unlike other converters, external software is not required to control data flow. The RS-232 input is wired for DCE through a DB9 female connector, and RS-422/RS-485 signals are interfaced through a removable terminal block. To supply external power to the terminal block, you need our 120-VAC/12-VDC Wallmount Power Supply (PS1003). For RS-232, the connection requires RD, TD, and Signal Ground. In RS-422 mode, the driver is always enabled for full-duplex communications. A twisted pair is required for transmit, and ...
