APPENDIX B
IENA 8 packet structure
All packets utilize UDP and therefore include the standard Ethernet, IP, and UDP layer header.
The UDP packet payload implements the IENA format as follows:
Channels 0,8,16,24,32,40,48,56
Word Value Comment
0 Key Key-Set by IEna KEy command
1 0x001B Size in 16-bit words (decimal 27)
2 Time - Bytes 5&4 Time in us from 1 Jan 00:00:00
3 Time - Bytes 3&2
4 Time - Bytes 1&0
5 0x0000 Status-Set by IEna STatus command
6 Sequence Rolling 16 bit counter
7 Ch 0 pressure - Bytes 3&2 32-bit IEEE-754 floating point
8 Ch 0 pressure - Bytes 1&0
9 Ch 8 pressure - Bytes 3&2 32-bit IEEE-754 floating point
10 Ch 8 pressure - Bytes 1&0
11 Ch 16 pressure - Bytes 3&2 32-bit IEEE-754 floating point
12 Ch 16 pressure - Bytes 1&0
13 Ch 24 pressure - Bytes 3&2 32-bit IEEE-754 floating point
14 Ch 24 pressure - Bytes 1&0
15 Ch 32 pressure - Bytes 3&2 32-bit IEEE-754 floating point

found. Below
26 0xDEAD End marker -Set by IEna ENd command
Notes:
Each KMPS will be provided a unique Key value by the customer.
The value of Key field in the IENA packet will be different for each set of channels and will be
determined by the customer supplied Key as follows:
KEY Channels
Key 0,8,16,24,32,40,48,56
Key + 1 1,9,17,25,33,41,49,57
Key + 2 2,10,18,26,34,42,50,58
…
Key + 7 7,15,23,31,39,47,55,63
