System Operation in "Network Master" mode
Once the Breakout box has booted up, it will begin sequentially scanning and
interrogating all the units stored in its address list. This will be evident by the
RS485 RX and TX LEDs starting to flash on the front panel, and each device on
the network briefly flashing its COMMS LED (on amplifiers) or its RX/TX LEDs
(Breakout boxes) in sequence.
Remember – only one Breakout may be set to "Network Master" on any network,
and ICORE cannot be used at the same time, unless the unit is either switched
off, or switched out of "Network Master" mode (requiring a re-boot).
It's sometimes quicker just to turn off the "Network Master" if changes to the
system through ICORE are not involving this unit.
Additional Functions of the GPI port – Mute and Standby
GENERAL ERROR
LEDs driven directly from
GPI port, or send lines to
building management system...
In addition to the output lines that can be used to drive LEDs or send signals to
building management systems, there are also input lines that can be configured
to mute all connected amplifiers or force them into standby.
These lines may be disabled on the Breakout by changing the device "GPIO
Config." input property in ICORE as required (see page 26).
Their action differs slightly depending on whether the unit is in "Network Master"
mode or not. If set to be a "Network Master", then grounding pin 6/7 will
standby/mute all amplifiers on the entire network. If the unit is not a network
master then it will only standby/mute amplifiers connected to its local RS485
port. These need to be LATCHING connections to work correctly!
