VT6306B and 100BASE-T1piggy / 1000BASE-T1piggy
The six-channel Ethernet Network Module VT6306B is a high-performance Ethernet interface module for the VT System. The base module provides two 100BASE-TX/1000BASE-T channels and a socket for a piggyboard with six Automotive Ethernet channels.
The piggy board modules 100BASE-T1piggy 1101 rsp. 1000BASE-T1piggy 88Q2112 carry the physical bus access chips as well as the typical VT System fault injection capabilities like line breaks and shortcuts. The channels 1-3 of the 100BASE-T1piggy 1101 additionally provide an adjustable resistive signal attenuation.
The module including the piggyboard offers high performance and low latency times because a PCI Express cable is used to connect the network interface to the real-time module VT6020, VT6060 or a Vector Rack PC. If connected to the Vector Rack PC, a PCI Express cable connector (x1) is needed. This may be added to the Vector Rack PC using an appropriate expansion card.
Hint: VT6306 cannot be operated at any PC but requires mandatorily a Vector PC, either VT6000 or a Vector Rack PC with a suitable PCI Express adapted card.
