The EYS290 novaNet ISA bus
controller is part of the EY3600 family of systems. This ISA bus card
enables a
standard PC to be linked directly to the EY3600 novaNet system bus via
an RJ-11
(6/4) interface. The telegrams are exchanged between novaNet and the
superior
visualisation and management level via a dual-port RAM, which also
serves as a
temporary memory.
