You chose the communication protocol when placing your order. To check the communication settings, see and/or change the protocol or other communication settings, see the following sections.
| You need a converter to access the RS-485 and RS-422 interfaces directly with a standard PC. |
| You can access RS-232 and SDI-12 with a standard PC terminal, if for SDI-12, the Data in/out lines have not been combined inside the transmitter. |
