5. Hardware setup and topology
An ECH crate equipped with a CC24 Host Controller can be extended with up to 2 x 4 CC23 slave controllers using the green and
the yellow daisy chain CAN lines. Legacy CAN controlled crates can be connected at the end of each of these lines.
All CC2x controllers provide two independent CAN lines, that are separated by color coding, indicated by the LED of the CAN
connector. The upper CAN connector connects the YELLOW CAN LINE, the lower to the GREEN CAN LINE.
The address IDs of the connected crates are configured automatically, depending on the position in the chain following this
pattern:
LINE-ID
DEVICE-ADDRESS
Yellow line IDs
1 − 5
Green line IDs
8 − 12
