SKU CH-2NWV-P26JA

Adds sixteen RS232 serial ports via PCI Express with 15 kV ESD protection and hardware auto-flow control

  • Adds sixteen RS232 ports via PCIe slot
  • 15 kV ESD surge protection on every serial port
  • Hardware auto-flow control manages data flow
  • circuit and thermal protection safeguards transceivers
  • Standard-height bracket fits full-size expansion slots

16-Port RS232 PCIe Card

The Axxon 16-Port RS232 PCI Express Controller Card adds sixteen serial ports through a single PCIe slot. It targets industrial users and developers who need many RS232 connections for legacy equipment or data acquisition. The card uses a standard-height mounting footprint for typical chassis.

Standard PCIe Installation

Installation follows the usual PCIe add-in card process using the standard-height bracket. The board is plug-and-play compatible, so most operating systems recognise it without extra driver media. Ensure the host has a free PCIe slot and sufficient bracket space for the two included cable assemblies.

15 kV ESD Port Protection

Each of the sixteen RS232 transceivers provides 15 kV ESD surge protection alongside short-circuit and thermal safeguards. This hardening protects the host system when long cables run through electrically noisy environments. The transceivers also integrate an onboard charge pump for reliable 1 Megabaud signalling.

Questions about this item

How can I verify the 16 RS232 ports are communicating correctly after installing the LF729KB card?

Open Device Manager to confirm all sixteen COM ports appear without errors, then run a loopback test on each port using a terminal program to validate transmit and receive signals.

What cables or accessories come with the 16-port RS232 PCIe card and what must I source separately?

The card includes the breakout cables that provide the sixteen DB9 RS232 connectors; you only need a free PCIe slot and any DB9 serial cables for your peripheral devices.

Which version of the Axxon 16-port RS232 controller should I choose for a standard-height PCIe slot?

The LF729KB model is built with a standard-height mounting footprint, so it fits full-size brackets directly; no low-profile variant is offered for this part number.
