PMM0915 is a TTL to RS232 converter module via MAX232 TTL to RS-232 Interface chipset which allows ICs to use RS-232 differential signaling for robust long-distance serial communications. This module allows for data transmission and communication of a CPU/MCU with any RS232 device either using full mode (full duplex) or null mode (half duplex).

PMM0915 has ±15-kV IEC ESD protection pin to pin and operate at data signaling rates up to 250 Kbit/s and a maximum of 30-V/μs driver output slew rate. Moreover, it has the ability to work under difficult environmental conditions.
