Figure 14: RS232 Interface Example Schematic
NOTE:
→ Circuit above shows an example of a RS232 interface configuration with
external transceiver powered by the TMCC160 internal generated 3.3V
supply voltage. Circuit above only shows an example, many other RS232
transceivers are available.
For remote control and host communication the TMCC160 provides a two wire
RS485 bus interface. An external RS485 transceiver is required to integrate the
TMCC160 into a RS485 bus structure. An example circuit is shown below, several
other RS485 transceivers are available.
NOTE:
→ TMCC160 is capable to supply a RS485 transceiver with the internal 3.3V
power supply.
→ For a proper RS485 operation following items should be taken into account
when setting up an RS485 network:
