Is there a RS232 Interface Adapter for Raspberry Pi?
RS232 serial communication is standardized at the hardware layer. RS232 communication can also achieve longer distance runs ( maximum distance depends on baud rate ). The following interface adapter is available for $9.99 USD:
What kind of serial port does Raspberry Pi have?
Serial ports (RS-232) are still useful to me, and a Raspberry Pi is a great platform to use as a low-cost serial terminal for a packet radio terminal, serial debugger, or general serial interface. This post shows two ways to adapt the Raspberry Pi’s TTL serial port to a DB9 connector for use as an RS232 serial port:
Can a Raspberry Pi connect to a laptop?
If you are just looking to communicate to your Raspberry Pi via its serial UART, then you may prefer a USB interface. Most recent models of computers and laptops do not have the traditional RS232 DB9 port anymore, so connecting using a USB port may be preferred. The following adapter is only $5.47 USD and it provides a USB to serial converter chip:
What kind of adapter do I need for Raspberry Pi?
I use NulSom’s Ultra Compact RS232 to TTL Converter with Male DB9 . This converter fits within a DB9 back shell. The converter has solder terminals that I connected to female header adapters, and connected to pins 4, 6, 8, and 10 on the Pi. The setup is more compact compared to using a USB adapter.
