Abstract
The Raspberry Pi has a UART interface to allow it to perform serial data communications. The data lines used are 3.3 V logic-level signals and should not be connected to TTL logic (+5 V) (they also are not RS-232 compatible). To communicate with equipment using RS-232, you will need a converter module.
