Why COM Ports Still Matter in Industrial Projects
Many modern computers rely heavily on USB communication.
However, industrial automation and control systems still widely use RS232, RS485 and RS422 interfaces because of their stability and long-term compatibility.
In many projects, external USB-to-serial adapters create additional failure points and increase maintenance complexity.
For this reason, system integrators often prefer industrial PCs with native COM ports when building automation systems, kiosk controllers and machine control platforms.
Why Choose SNR-N6?
SNR-N6 is designed for industrial control projects that require reliable serial communication, stable networking and continuous unattended operation.
Compared with standard mini PCs, SNR-N6 provides 6 COM ports, RS485 / RS422 support, dual Intel LAN, 14 GPIO, 9–36V wide-voltage power input and fanless aluminium construction. These features make it suitable for factory automation, kiosk control, machine control, access control, parking systems, transportation equipment and industrial data collection.
For projects with multiple serial devices such as PLCs, printers, card readers, barcode scanners, scales and relay controllers, SNR-N6 helps reduce the need for external serial expansion adapters and simplifies system integration.
