REP Port Setup

REP, or Retry Enhanced Protocol, is a custom designed protocol for reliably transfering data packts from the NetRS to one or two external client programs. The protocol has two objectives:

The REP protocol is based on SCTP (Stream Control Transfer Protocol), a standard networking protocol for the semi-reliable transmission of streaming data. SCTP allows the same connection to carry several channels of information. REP defines three channels:

Using an REP stream requires an external client program which establishes a connection to the REP port, accepts the Realtime Data, monitors which packets have been received, manages retry requests, etc. The client program is also responsible for directing the received data to other realtime applications or to long-term storage.

To use the REP protocol, an REP port must be specified from the I/O Port Configuration page. Currently, only the Binex stream format is supported over an REP stream. Only one REP port can be defined. An REP Port Number must be defined. This can be any value between 1024 and 65535.
