• All other LED display combinations mean that there is a fault in the essernet
®
module or that measuring operation is active.
• Connect cable shielding to the appropriate terminals!
• The data signalling rate and connection cable to be used is governed by
the module type installed. In a network you may only use essernet
®
modules with the same data signalling rate.
