    Product Overview This manual gives information on the CAN Spider active CAN bus hub. The CAN Spider can connect up to four fiber optic ECAN527-2 PC/104 CAN bus interface boards together. Other CAN bus devices may be connected to the galvanically isolated twisted pair CAN port. This structure enables flexible expansion of CAN Spiders as well as connection of twisted pair CAN devices to your network.
