7.3 RS-485 connection
Once the gateway has been connected to the RS-485 bus (see Chapter 5.4), you may connect the
RS485 bus to your PC. This can be done by using a RS485–RS232 converter or a RS485–USB
converter.
Procedure 1 Connect the RS-485–RS-232 converter or the RS-485–USB converter to your PC.
2 In the case of the RS-485-USB converter install any driver that is delivered with the device.
3 To find out to which COM port the converter is connected, open the Windows device manage.
e.g. for Windows XP:
Start > Settings > Control Panel > System > Hardware > Device Manager.
4 Under "Ports (COM & LPT)" you should see the converter and the COM port assigned to it
5 Note the COM port (in this case USB Serial Port (COM5)) and the baudrate etc. as you will
need them to set up communication
