The design implied by the above diagram indicates specific requirements for the PI written software.

Command/Control Software

• Must send its commands via UDP datagrams
• Must allow the operator to change the host (IP) and UDP socket to which those datagrams are sent
• Must receive instrument status via UDP datagrams
• Must allow the operator to change the host (IP) and UDP socket on which those datagrams are received

Instrument Software

• Must receive its commands via UDP datagrams
• Must allow the operator to change the host (IP) and UDP socket on which those datagrams are received
• Must generate either a status datagram or data datagram which will allow the ground operator to observe affect of command
  • Status datagrams will be forwarded to the command/control software running on the ground
  • Data datagrams will be pulled in by the RAF Aircraft Data System and made available through that system
  • Instrument PIs are encouraged to send both types of datagrams
• Must allow the operator to change the host (IP) and UDP socket to which status and/or data datagrams are sent
