For reliable fieldbus function, line termination must be arranged in both ends of the
transmission line. For a G5 Instrument placed at the end of the line, terminate line by
placing a 121-ohm resistor between CAN L (pin 2) and CAN H (pin 4).
For configuration of the adaptor an EDS file is supplied with the instrument that should
be installed in the master. Note that the EDS file is a generic type supplied by the
module manufacturer. The file doesn’t contain any reference to the G5 Instrument or to
BLH Nobel.
