CAN-BUS terminating resistor (R)
On a CAN-BUS connection, the first and last elements have to be provided with a resistor. This resistor must be
switched on / off using switch n
o
. 4 on each module.
If the first or last element is a Crate:
For this, set switch 4 on the Crate to the ON position. The figure on the left shows an assigned CAN-BUS input on
the left side of the PCB: In this case, the left switch has to be set to OFF (no resistor, as the CAN-BUS connection
is not ending here), the right switch n
o
. 4 must be ON (resistor active, as the CAN-BUS connection is ending
here).
Switch 4 of the module in the middle has no function !
If the first or last element is a NDP:
Here, the resistor must already be implemented into the NDP ex works; see also further down in the manual.
Panic (PNK)
The modules to be activated when operating the PANIC button have to be preselected using Switch 3< for this,
set Switch 3 to ON. Use this setting for each of the modules.
Control (CTR)
The modules to be activated when operating the CONTROL button have to be preselected using Switch 1< for this,
set Switch 1 to ON. Use this setting for each of the modules.
Update module (FWE)
You can have the NDP update the modules to a current software version. If you want to exclude a module from
an update, „write-protect“ this module using Switch 2. To do this, set Switch 2 to OFF.
For modules to be updated by the NDP, you have to set Switch 2 to ON.
Use this setting for each of the modules.
