KAD/BCU/105
Fast Ethernet KAM-500 backplane controller and packet generator
Description
The KAD/BCU/105 is a full-duplex 100BaseTX Ethernet KAM-500 backplane controller, programmer and packet generator.
In acquisition mode some or all acquired data is transferred from the backplane to the on-board CVT. On-board, it is packetized into a user-defined structure. Once full, the packet is transmitted via UDP.
Any number of user-defined IENA packet structures can be handled simultaneously. Different packet identifiers, packet sizes and destination IP addresses can be individually programmed for each packet type. Destination IP addresses can be unicast, multicast or broadcast.
Upon reception of a programming packet, the module immediately exits acquisition mode and switches to program/verify mode. In program/verify mode it can read or write data blocks to or from any module within a KAM-500 chassis.
The KAM-500 backplane controller supports chassis programming via Ethernet. Synchronization is achieved using the IEEE 1588 PTP.
The KAD/BCU/105 supports IPv4 networks with fixed IP address allocation, including user-assignment of the module’s IP address. The module is factory-programmed with a unique Ethernet MAC address.
