4.1.4 Connecting the Bus Line
Connect bus wire NET A to terminal 79 and NET B to 80 of the terminal connector.
Terminal Connection
79 NET A*
80 NET B*
61 Drain**
NB!
*Note: For free topology wiring the option is insensitive to the polarity of the bus-terminals.
NB!
**Note: Term. 61 (Drain) offers a RC-junction to ground and should not be used for grounding of shielded cable. Ground the shielded cable at the de-coupling
plate by removing cable insulation at contact point.
4.1.5 Maximum Cable Lengths
Network topology Maximum cable length
Free topology without repeater 500 m
Free topology with one repeater 1000 m
Free topology maximum device-to-device 500 m
Bus topology single terminated 500 m
Bus topology double terminated without repeater 2700 m
Bus topology double terminated with one repeater 5400 m
Bus topology maximum stub length 3 m
Use of the same cable type throughout the entire network is recommended in order to avoid impedance mismatch.
4.1.6 System Specifications
Up to 64 FT-X1/FTT-10 transceivers, are allowed per network segment.
NB!
Note: The Free Topology LonWorks runs at 78 Kbps only.
