The GLX504 is an extension to the data logger series GL5300 and GL3400. Long tap lines on a CAN FD can lead to interferences. The GLX504 is the solution to avoid such problems and guarantee an optimized and troublefree connection of a GL5350/GL5370 to an already existing CAN FD. This enables you to connect the data logger offset from the CAN bus, and without any disadvantageous extension of the existing CAN.
