Tripp Lite's AT style gender changer has gold plated connectors and will change a DB9M connector or port to a DB25F connector or port to accept a DB25M cable or device. Gold plated copper contacts provide maximum conductivity and keep data loss to a minimum. 28 AWG stranded tinned copper conductors are individually insulated in polypropylene. This minimizes cross talk and ensures high-speed, error-free transmission.
