2.2.3.1 Hmi-26
Connections to a Sonix Hmi-26 should be wired pin-to-pin
without any crossover. The maximum cable distance that
the system can support for an Hmi-26 is 750 m, connections
longer than this are not supported and are likely to result in
unreliable operation. The second pair is used for bi-directional
RS485 at 38,400 8-N-1 baud for control and status reporting.
The screen connection is required as part of the 0V return.

N
The cable connections to the unit are different between Hmi-26
and Hmi-5 access panels.

2.2.3.2 Hmi-5
Connections to a Sonix Hmi-5 should be wired pin-to-pin
through the Hmi-Br (see section 3.2.3.2.1). 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 unreliable operation. The data is received
and transmitted on separate cores at 9,600 8-N-1 baud; it is
used for control and status reporting. The screen connection is
required as part of the 0V return.
