[93]
Part No.: 669950
13.1 Basic settings
Before connecting a bus participant
or hooking up an external CAN bus
system, the following presets must
be applied in the HMG 4000:
Baud rate
To configure participants or log messages, the HMG 4000 must be set to the baud
rate of the participant or the external bus system. Baud rates of 10kBit/s to 1 MBit/s
are possible.
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 connect
"Connect"
Message acknowledgement
Message acknowledgement needs to be switched off or on depending on the
application.
Passive monitoring, do not acknowledge
This setting should always be selected when the HMG 4000 is connected up to a
CAN bus system so as to log messages passively (unnoticed).
Active monitoring, acknowledge 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.
