Port-powered RS-232 to RS-485 Converter(TLC485)

Features 1. Port-powered from RS232 port (TXD,RTS,DTR): no external power is necessary 2. Convert RS-232(TXD,RXD signal) to RS-485 signal 3. Plug-and-Play (hot-pluggable, Data format Auto-sensing & Self-adjusting) 4. Data direction auto-turnaround, no flow control is required 5. Point to multi point, support 128 nodes loopback Introduction The TLC485 is a bi-directional port-powered RS232 to RS485 converter. It can convert any standard full duplex RS232C port to any two-wire balanced half duplex RS485 port. In simple terms, it will convert any RS232 signal to a RS485 signal and vice versa. The unit is powered from the RS232 data lines. It also supports data direction auto-turnaround. Therefore, no external power or flow control is required. The data direction auto-turnaround automatically enables the RS485 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers.
