The Hand-held microphone hanger can be damaged by rough
handling, take care when mounting the unit.
4.2 Glanding
The Sonix Hmi-5 is typically supplied with 2 or more
M20 tapped holes for cable gland terminations.
Warning:
Cable glands must be installed and
inspected correctly to maintain Ex and IP ratings.
4.3 Data and Audio connections
Data and audio connections to the unit should be wired
with 2 pair and screen cable, with both individual and
overall screen for improved noise performance. The unit
uses 1 pair for outgoing audio with incoming phantom
power superimposed on the top. The second pair is
used for bi-directional serial communications at 9,600
8-N-1 baud for control and status reporting. The screen
connection is required as part of the 0V return. The
maximum cable distance that the system can support
for an Hmi-5 is 300 m, connections longer than this
are not supported and are likely to result in un-reliable
operation.
Connections to a Sonix Hmi-Barrier should be wired pin-
to-pin without any crossover.
