3.5 Working Online 3.5.1 Communications Overview
Referring to the illustration above, in online mode the HELIX DN9848E RCS laptop/PC and units
exchange the following messages:
Metering Requests
and Responses
These obtain data for the Input, Dynamic EQ and Output ‘LED’ meters of
HELIX DN9848E RCS screen. The HELIX DN9848E RCS continually polls
the units in rotation.
Get All Requests
and Responses
These obtain settings from the specifically addressed unit. These may be
initiated by the user or automatically by the HELIX DN9848E RCS.
Data Packets These carry the processor settings from the laptop/PC to the specifically
addressed units. Data Packets are only transmitted when you make
changes at the laptop/PC.
What happens when the wireless connection is interrupted
If the wireless connection drops, for example, due to a pillar interrupting the radio signal, the HELIX
DN9848E RCS suspends the Add-In settings so that no further changes can be made, although you may
freely navigate between screens. However, due to the network speed, there will be a delay during
which you may make some changes that are not registered at the unit.
During the drop, the HELIX DN9848E RCS continues to poll the units for metering requests. When a
response is detected, that is, the wireless connection is restored, the HELIX DN9848E RCS will come
back online as follows:
If you were making changes when the connection dropped, that is, data packets were lost, the
HELIX DN9848E RCS will send a Get All request to the system to re-synchronise the HELIX Add-Ins with
their physical counterparts before unfreezing the Device Screens. Your last change(s) are rolled back.
Synchronising to the physical units, that is, to the last settings you heard, avoids the possibility of
extreme changes in volume due to any dramatic adjustments you may have made due to the apparent
lack of effect as the units went offline.
