RS-232

— the presence of an RS-232 service interface in the recorder (also known as a COM port). Through such a connector, it is usually possible to remotely control the device’s operating parameters from a computer or specialized equipment using appropriate software. Also, the RS-232 port can be used to update the recorder firmware.
