MD-309 User Manual 21Appendix : Switching RS-485 to RS-232 When configuring Etung device with RS-485 interface, in order to connect the device to PC, it is required to switch RS-485 interface to RS-232 interface. Etung provides two kinds of switching methods: via RS-485 to RS-232 convertor, and via 9-pin adapter serial line. Details are described below. 1) RS-485 to RS-232 Convertor This method requires a RS-485 to RS-232 convertor (as shown in Figure Appendix 3-1), as well as an adapter line from RS-485 to RS232 (as shown in Figure Appendix 3-2), this line is delivered for free by Etung when
MD-309 User Manual 22customer buys devices the first time. Connect the 9-pin end of the adapter line to the 9-hole serial port of the device, connect the other end of the adapter line to the 9-pin end of the convertor (not including convertor terminal) as shown in Figure Appendix 3-3, and then connect the 9-hole end of the convertor to PC.
