Resistors R135 and R136:
0Ω resistors as connection earth - ground M. M is connected to earth in the delivery state. These resistors should
be removed only for the purpose of preventing disturbance caused by earth loops, i.e. if the electronics ground is
connected to earth in some other way (e.g. via signal leads or to the ground of the power supply). The earth -
ground M connections on the other electronics boards must then also be separated (see description of basic
converter unit or of other option boards).
Plug-in jumpers:
Pin 1 of the plug-in jumpers has a screen-print marking. The distance between pin 2 and pin 3 on X1 and X5 is
slightly larger to prevent them from being linked in a meaningless connection. Examples:
Pin 1 2 3 Pin

The purpose of the bus terminator is to prevent line reflections at both ends of the bus cable. It must be
activated:
on both connected devices with a point-to-point connection
only on the devices connected at the start and end of the bus with a bus connection.
ó
Bus terminating resistors are soldered in at the transmit output of interface 2.
