Linux (kernels 2.4.x and 2.6.x). This versatility allows for smooth integration
into a wide array of automation platforms. As a part of the CA-134I series,
onboard Tx and Rx LED indicators for each port provide real-time visual
feedback on communication status, which helps users quickly assess port
activity and system health. Designed with scalability in mind, the CA-134I supports
seamless integration into existing infrastructure while ensuring consistent
performance in demanding environments.
RS-422/485 Serial Standards and 2 kV Isolation
Equipped with a PC/104 bus and a 40-pin box header
connector, the Moxa CA-134I module board ensures reliable connectivity and
efficient data exchange. Onboard DIP switches allow for quick configuration of
the I/O base address, interrupt vector, and serial interface, offering
flexibility during installation. Supporting RS-422 and RS-485 serial standards,
the industrial PC/104 enables robust, industrial-grade communication.
Additionally, 2 kV optical isolation safeguards against electrical interference
to ensure secure and uninterrupted data transmission in electrically noisy
environments. You can find out more about these multiport serial boards in the
