HP Internal Serial Port Card

This HP 3TK82AA add-on card provides an internal serial port for select HP EliteDesk and ProDesk business desktops. It enables legacy device connectivity on compatible 600, 705 and 800 series systems.

Suited For and Not Suited For

It suits IT teams maintaining older serial peripherals such as barcode scanners, industrial instruments or console cables on supported HP desktops. It is not for systems outside the listed 600, 705 or 800 families, nor for users who need USB or parallel interfaces instead.

Compatibility Decides Fit
