Must correspond to the
‘Local Producer’ in the
EGD configuration. Not
necessarily the IP
address of the producer

These data types must
correspond to the
references in the EGD
range configuration.
These offsets
must correspond
to the offsets in
the EGD
configuration.
Refer to Appendix C.1 to see how many
items are being transmitted. Note that
the %Q, %I references are actually byte
references and not bit references as
they are always produced in multiples
of 8 and are always byte aligned.
