Notes
3.0 Protocol
hold all packets available for retransmission until acknowledgement is received. Incoming corrupted packets are dropped
and issues a retransmission request. The negotiation for acknowledgement, retransmission and dropping packets is
handled at the local interface level, without intervention of higher-level authorities. The SerB does not forward any packet
until it is fully received, verified, and acknowledged (if configured to verify).

3.1.2 Interface Packet Buffer Size
is the requirement to transmit higher priority packets first. Upon transmission failure, and retransmission, the retransmis-
sion may be held up and a higher priority packet interjected if one arrives.
3.1.3 Multicast Packets
an SWRITE function. The destination ID for the case scenario should be set to a multicast address elsewhere in the
system. The SerB shall perform a multicast by sending the SWRITE to the user designated multicast address, along with
the data.
issues an SWRITE multicast packet to the PPS multicast address. The SWRITE command is generated by the case
scenario.
3.2 sRIO Specification
primarily as an sRIO end-point, but will work as a bus master to perform multicast operations.
section, version 1.3 of the specifications will replace these section files when they are approved by the Steering
Committee:
The SerB is a packet-handling device. The SerB may be configured to require all packets to be acknowledged, and
The sRIO specification requires a maximum packet size of 256 bytes plus overhead. The SerB fully complies to this
The sRIO specification has defined buffer sizes for the transmit and receive buffers. Included in the buffer specification
The SerB has no special multicast capabilities. To perform a multicast, the case scenario should be set up to perform
Waterlevel multicast in the PPS application is done the same way. When the waterlevel event is triggered, the SerB
The SerB serial interface is a standard 1x/4x serial port with sRIO capabilities. In the PPS application, the sRIO port act
