PL-106 (PL-101) can covert the data from RS-232C to half duplex RS-485(RS-422) signal. It don’t need additional power supply and can get the power directly from PC side. By it’s “Automatic Send Data Line Control” function, you don’t need to use RTS, just plug it and no need to install any hardware or software and work well under RS-485(RS-422) communication
- DB9-S/P space saving connector.
- RS-232C data interface fully compatible with PC.
- DB9 connector and 4-bit terminal are optional to RS-485 interface.
- Automatic direction control of transmitting data (TXD), zero-latency design.
