Connecting NI PCIe to Beckman-Coulter System Gold HPLC

Hi, all,

I inherited a never before used Beckman-Coulter System Gold HPLC and the computer containing the NI PCIe card. Although I do have all of the original packaging and parts to get the HPLC up and running, I seem to be missing an adapter to connect the NI PCIe-GPIB board to the serial System Gold input on the Beckman-Coulter solvent module. Any advice on where to find what I need?

Thanks much!
