Remote Control and Monitoring

Overview

There are three distinct methods of remote control available to the
amplifiers, allowing for various levels of system complexity. These may be
thought of as:

Basic Local System Control

•
Remote Monitoring and Control On-line via a Computer with ICORE
•
Remote Monitoring Off-line with a Breakout Box
•
These three methods can all be mixed, and are not mutually exclusive – so we
can have local control of an amplifier's muting, but still be connected to a PC with
ICORE if required.
When the PC isn't in use, the system can also be connected to a Breakout box for
off-line background monitoring, and all without reconfiguring any cables!
Basic Local System Control
The basic local control is all based around the use of the GPIO port to allow
amplifier(s) to be either muted, placed into standby, or have their gains adjusted
– the required input control is programmed via ICORE. Monitoring via a simple
logic output can be programmed, again via ICORE, and allows for checking of
the amplifier loads, protect status, excess limiting, or over-temperature
conditions. An additional isolated changeover relay can be used when the 3v3
logic isn't compatible with the required control system.
The setup and configuration of the amplifier is explained in the section entitled
"Example Uses of the GPIO Port Lines" on page 38.
Note the following points about local control.
Only one parameter can be controlled via the logic input.
Only one parameter can be monitored via the logic output.
Local control always takes precedence over the remote setting of the same
parameter – so local gain control will take precedence over remote
adjustments, and local muting will over-ride remote settings. This is to
allow for building management systems to assume ultimate responsibility
for the system, in emergency circumstances.
For an explanation on how to set up load monitoring, please see the section
entitled "Load Monitoring – What For and How" on page 45.
