limitation number of cards and gateway position

Post by ali »

Could you please let me know the reason for the below sentences?
"Each RevPi Core can handle up to 2 RevPi Gate modules."
" The RevPi Gate modules need to be physically located at the end of each RevPi Core installation."

Short answer: because of the internal neighbor discovery for the gateways.

Long answer: the gateways use a different communication protocol (ethernet, other modules rs485) and were initially build to be used as a pair of two devices. Therefore they are not build to proxy the discovery requests from other modules. As this would break the initialization of for example a dio, Gateways must be used as described.
