Integration - Handbook RAF Field Project Computing Handbook http: //wiki. eol. ucar. edu/sew/Aircraft/Handbook

Integration - Networking Two gigabit Ethernet networks Both have DHCP and NTP Both have real-time data feed Data Collection – 192. 168. 184. 0 RAF Data only Display / User – 192. 168. 84. 0 Power over Ethernet (Po. E)

Integration - Timing Network Time Protocol (NTP) IRIG-B 123 (AM) 1 Pulse Per Second (PPS) GPS antenna feed (special request)

Integration – Data Feed IWGADTS recommended data packet UDP broadcast on port 58800 We can provide UDP to RS-232 converters (request ahead of time) Packet has a 2 -3 second delay from actual acquisition You may request additional variables. This is not the same feed sent to the ground
