Quad RS485 Level Shifter
The RS485 level shifter converts the signals provided by the FT4232H into the voltage levels required by
RS485 devices.
RS485 connectors
Four 3 pin 5mm terminal block connectors provide the connection to RS485 peripherals devices. These
are CN5 for channel 1, CN8 for channel 2, CN11 for channel 3 and CN14 for channel 4 (The RS485 and
RS232 share the same GND pin which is the middle pin of these connectors).
Quad RS232 Level Shifter
The RS232 level shifter converts the signals provided by the FT4232H into the voltage levels required by
RS232 devices.
RS232 Connectors
Four 8 pin 5mm terminal block connectors provide the connection to RS232 peripherals devices. These
are made up from 3 connectors CN3, 4, 5 for channel 1, CN6, 7, 8 for channel 2, CN9, 10, 11 for channel
3 and CN12, 13, 14 for channel 4
