1 General 1. VSE 002 External RS-485 Module General External RS-485 Module VSE 002 is used to connect VAMP protection relays to a RS-485 bus. Additionally this module can be used with any device, which has a RS-232 or TTL serial interface, when an RS-485 interface is required. 2. Power supply The power for the module is taken from pin 9 of the D-connector or from an external power supply interface. There is a screw terminal (X1, see figure 1) for connecting an external +9...12Vdc power supply. 3.
VSE 002 External RS-485 Module 4. 4 RS-485 interface RS-485 interface The RS-485 interface supports 2-wire connection. The dip switch S1 is used to switch the termination and signal biasing resistors on or off. Termination ON OFF Interface type TTL RS-232 Figure 1. Dipswitch positions of VSE 002 The direction control of the RS-485 transceiver is done with the RTS signal or automatically.
