SMUGDESK

SMUGDESK 2-Port Industrial RS232 PCIe Serial Card x1 DB9

SKU CH-NGT6-0RZ1T

Adds two RS232 DB9 COM ports via a PCIe x1 slot for industrial PLC and POS equipment

  • Adds two DB9 RS232 COM ports via one PCIe x1 slot
  • PCIe 1.0 compliant and fits x4/x8/x16 slots for broad motherboard compatibility
  • Industrial-grade chip ensures steady long-running data transmission for PLC and POS gear
  • Full-height metal bracket installs easily in standard desktop and industrial PC chassis
  • Drivers included for mainstream Windows and Linux operating systems

Industrial RS232 PCIe Serial Card

This SMUGDESK adapter adds two DB9 COM ports through a single PCIe x1 slot, giving modern motherboards the legacy serial interfaces required by industrial equipment. It targets technicians and system integrators who connect PLCs, POS terminals or test gear that still rely on RS232 communication.

PCIe 1.0 x1 slot with x4 x8 x16 compatibility

The card fits any standard full-height desktop or industrial chassis and works in PCIe x4, x8 or x16 slots thanks to backward compatibility with the PCIe 1.0 specification. No external power connector is needed, and the metal bracket secures the DB9 ports for reliable cable retention in vibration-prone environments.

Dual DB9 ports for steady long-running transmission

The industrial-grade main chip maintains stable data streams at 232 rates across both ports simultaneously, handling factory control and hardware debugging workloads without dropouts. Throughput is limited to the RS232 standard, so applications needing higher-speed serial protocols will require a different interface.

Questions about this item

How many RS232 COM ports does the SMUGDESK card provide from a single PCIe x1 slot?

The card expands two standard DB9 RS232 COM ports from one PCIe x1 slot for connecting industrial devices such as PLCs, POS terminals and test equipment.

Does the industrial-grade main chip handle continuous operation without overheating or excessive noise?

The industrial-grade main chip is designed for steady long-running data transmission, and the card has no fan, so it operates silently in desktop or industrial PC chassis.

Which operating systems already have driver support for this serial card?

Complete driver packages are included for mainstream Windows and Linux operating systems, so the card works immediately after installation.
