Note:
See
Installation and wiring (page 14)
chapter how to connect/disconnect built-in 120Ω terminator in
InteliVision 5 CAN.
Note:
CAN bus ISO 11898 standard recommends a maximum un-terminated stub length of 0,3m for a 1Mbps
signaling rate. Using 50 / 250kbps rate implemented in ComAp controllers and careful CAN bus design, longer
stub lengths can be acceptable. It is recommended to construct cable stubs (un-terminated branches) as short
as possible, preferably up to 1m.
Extending the CAN bus length, “T” network configuration, interconnection of CAN bus segments with different
speed (50 or 250 kbps) can be realized by I-CR module (CAN repeater) provided by ComAp. See corresponding
documentation for more details.
2.3.5 Communication detection
Connection is established in case of the communication parameters are set correctly, otherwise the
communication error screen is displayed.
Use ↑ or ↓ and choose appropriate address and press Enter.
If communication parameters are correct the error screen disappears. InteliVision 5 CAN identifies connected
controllers and configuration is downloaded automatically without any additional dialogue. In case of need,
communication addresses can be modified in Communication menu – see
.
