Dual RS485 Level Shifter
The RS485 level shifter converts the signals provided by the FT2232H into the voltage levels required by
RS485 devices.
RS485 connectors
Two 3 pin 5mm terminal block connectors provide the connection to RS485 peripherals devices. These
are CN5 for channel 1 and CN9 for channel 2 (The RS485 and RS232 share the same GND pin which is
the middle pin of these connectors).
Dual RS232 Level Shifter
The RS232 level shifter converts the signals provided by the FT2232H into the voltage levels required by
RS232 devices.
RS232 Connectors
Two 8 pin 5mm terminal block connectors provide the connection to RS232 peripherals devices. These
are made up from 3 connectors CN2, 3 and 4 for channel 1 and CN6, 7 and 8 for channel 2 The RS232
and RS485 share the same GND pin.
