Velemann K8047 data to COM Port

Hello, I am constructing a seismometer, type Leemann Seismometer (see Internet!). The primary signal is amplified by a self constructed amplifier, then the signal goes to the Vellemann K 8047. It works without problems, but I need the signal from the K8047 be sent to a COM Port, COM 1 or COM 1 until 8, because I will have sent the signal to a programm called amaseis or jamaseis. This programm needs to get the data at a Com port (1 until 8 is possible).
Has anyone an idea how to solve this problem?
