(a.k.a. “ESTR” and “ES-trib”). Full tributary
ESBus automation protocol, compliant with
SMPTE EG 29-1993, and all associated nor-
mative references. The protocol supports all
standard bit rates from 300 to 115.2 kBPS.
Flow control is an advantage with this proto-
col.
exclusion

puts. Example: lockout of a test signal from
bus leading to transmitter.
