Figure 2-8: Update complete 20 MD-309 User Manual Appendix : 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 21 MD-309 User Manual customer buys devices the first time. Figure Appendix 3 -1: RS - 485 to RS -232 Convertor Figure Appendix 3 - 2: Adapter line from RS - 485 to RS- 232 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. 22 MD-309 User Manual Figure Appendix 3-3: connection diagram 2) 9-pin adapter serial line(RS-485 serial line) This method requires RS-485 to RS-232 convertor, and 9-pin adapter serial line (as shown in Figure Appendix 3-4). Figure Appendix 3-4: 9-pin adapter serial line First, connect the red and yellow line of the line end on 9-pin adapter serial line to the convertor terminal of the convertor, the order is: plug the red line into T/R+ port of the terminal, and yellow line into T/R- port of the terminal, and other lines are not required to connect, as shown in Figure Appendix 3-5. 23 MD-309 User Manual Figure Appendix 3-5: Line connection order Then, connect the 9-pin end of the 9-pin adapter serial line to the interface of RS-485 device, and connect 9-hole end of the RS-485 to RS-232 convertor to PC, as shown in Figure Appendix 3-6.
