Internal Parallel RS-232 Adapter DeLOCK 90413

The DeLOCK 90413 internal PCIe adapter provides one parallel and one RS-232 serial interface on a single low-profile expansion card. Designed to fit into an available PCIe slot inside a desktop PC, the card expands legacy connectivity options for printers, industrial controllers, measurement devices and other equipment that require parallel or RS-232 connections. The adapter supports data transfer rates up to 0.0004608 Gbit/s and includes a 256 B FIFO buffer to help manage serial data flow. Compact dimensions make it suitable for small form-factor systems.

Advantages

This internal Parallel RS-232 adapter offers reliable hardware-level support for legacy interfaces without occupying external ports. The integrated FIFO buffer reduces CPU overhead during serial communication, and the low-profile bracket and compact board size simplify installation in slim desktop cases. Native compatibility with common Windows versions ensures straightforward driver support and stable operation for connected devices.

Suitable for

• Connecting parallel printers and legacy parallel devices
• Serial communication with modems, PLCs and industrial controllers via RS-232
• Integration into small form-factor or standard desktop PCs requiring additional legacy ports
• Use in measurement, automation or point-of-sale systems that rely on serial or parallel interfaces

How to use

Power off the PC and open the case according to the manufacturer's instructions. Insert the adapter into an available PCIe slot and secure the bracket to the chassis. Reassemble the PC and power it on. Install the appropriate drivers for your Windows version if they are not detected automatically. Connect parallel and RS-232 devices to the external ports on the card using compatible cables, then configure communication parameters (baud rate, parity, stop bits, flow control) in the host application or operating system device manager as required by the connected equipment.

Usage recommendations

Use shielded cables for RS-232 connections where electromagnetic interference is a concern, and verify pinouts for parallel and serial connectors before connecting legacy hardware. Ensure drivers match the installed Windows version and keep system firmware and OS updates applied to maintain stable operation.
