DESCRIPTION
PMM0912 is a TTL to RS485 converter module via MAX485 TTL to RS-485 Interface chipset which allows ICs to use RS-485 differential signaling for robust long-distance serial communications. This module allows for data transmission and communication of a CPU/MCU with any 2-wire RS485 device over large distances up to 1200m (4000’).
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.
