4. Functionality
The Moxa CI-134IS functions as a multiport serial communication interface card that enables PCs to communicate with multiple RS-422 or RS-485 devices simultaneously. Each of the four ports can be configured independently for RS-422 or RS-485 operation, allowing flexible deployment in mixed communication environments.
How It Works:
When installed in a PC’s AT (ISA) slot, the CI-134IS provides four additional serial communication channels. Each port is electrically isolated and surge-protected, ensuring that electrical disturbances on one port do not affect the others or the host system. The card’s onboard controller manages data transmission and reception, while the auto data direction control feature automatically switches between transmit and receive modes in RS-485 half-duplex communication, eliminating the need for manual control signals.
Use Cases and Applications:
- Industrial automation systems connecting PLCs, sensors, and actuators
- Building management systems (BMS) and HVAC control networks
