The main problem with gauge link is that you need to purchase the gauge link device.
When you use or have the MUX series of devices the digimatic interface products connect through MUX to the serial port through the MUX. P.S. MUX stands for Multiplexor. There are a number of types of these devices, including off the top of my head the MUX10, MUX2 and MUX50 In summary Gaugelink would not be suitable as the interface device exists in the form of the MUX.
