DESCRIPTION

PMM0914 is a TTL to RS422 converter module via SP490E TTL to RS-422 Interface chipset which allows ICs to use RS-422 differential signaling for robust long-distance serial communications. This module allows for data transmission and communication of a CPU/MCU with any RS422 device over large distances up to 1000m.

Earthing the module by connecting its terminal to ground gives it an excellent anti-jamming and anti-lightning effect, thus making it more secure and perfect for industrial use. Moreover, it has the ability to work under difficult environmental conditions.
