HP Internal Serial Port (600/705/800) interface cards/adapter

The HP 3TK82AA is an internal serial interface card designed for business environments that require reliable legacy serial connectivity. The card provides a standard serial output in a compact, lightweight module that can be integrated into compatible HP systems and third-party platforms where a dedicated serial port is needed. Its small physical footprint and unobtrusive weight make it suitable for installations with limited space or where additional I/O expansion is required.

Advantages

The interface card offers a stable serial connection for devices that rely on RS-232/serial communication, enabling continued use of existing peripherals and industrial equipment. Its internal form factor preserves external space and reduces cable clutter. The low weight and compact dimensions facilitate simple installation and handling during system upgrades or maintenance. The product colour and discreet design allow it to blend into rack-mounted or desktop configurations without drawing attention.

Key specifications

How to use

Install the interface card into an appropriate internal expansion slot of a compatible host system following the manufacturer's service manual and safety procedures. After physical installation, verify that the host firmware or operating system detects the serial interface and install any required drivers or system updates. Connect serial devices using the appropriate cabling and configure port parameters such as baud rate, parity, data bits and stop bits to match the attached peripheral. Test communication with terminal software or the device's management tools to confirm correct operation.
