Edition 2016-03-08 - V01 R04
[43]
Part No.: 669950
Internal load resistor
The internal load resistor needs
to be connected if the HMG
4000 is hooked up to the CAN
bus system at the end of the bus
line as the "last participant",
rather than using a branch line.
If the HMG 4000 is connected
using a branch line, the internal
load resistor may not be
connected.
"Do not switch on” "Switch on"
Message acknowledgement
Message acknowledgement needs
to be switched off or on
depending on the application.
Passive monitoring, do not acknowledge
This setting must always be selected when the HMG 4000 is connected up to a CAN
bus system so as to evaluate pre-defined messages passively.
Active monitoring, acknowledging messages
To test or to commission individual bus participants, for example, it is often
necessary to acknowledge the receipt of messages. In cases like this, this setting
must be selected.
