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
