Instruction Manual – BCS Basic Control Structure Protocol
Executing Presets
Presets Overview
This chapter provides information for executing local presets and for defining and executing global
presets using BCS commands. Presets are not supported on all systems (see Appendix A on page 25).
Local Preset
A local preset is a predetermined collection of switches (on the same level) to be routed simultaneously.
Executing a local preset will affect only those inputs and outputs specified, not the whole system.
If your system supports local presets, they must be defined (created) in XNConnect and then loaded into
the system. For directions for creating local presets, see the XNConnect Help file.
Global Preset
A
global preset allows you to replicate an entire system state (all signal routings regardless of the
number of levels involved), including audio gain/volume settings. If your system supports global
presets, they can be defined (created) using BCS commands during runtime and stored by the system.
If the system is reconfigured, global presets may be lost, depending on the method used to load the
configuration file (see the XNConnect Help file).
Local Presets
A local preset is a set of switches on a single level that is stored in a system’s configuration file.
If requested, local presets can be programmed at the factory; contact your AMX representative. To
program them yourself, use the XNConnect software located on the
AMX AutoPatch CD
or at
www.amx.com
.
General Rules for Local Presets
Executing a local preset does not change any system routings that are not part of the preset.
Local presets cannot be used to change any of the audio settings.
If two local presets are executed in the same command, both will be executed. If both include
routing instructions for the same input or output, the input or output will be routed according
to the last local preset entered.
You can execute multiple local presets on the same level by including a space between each
local preset number in the BCS command.
You can execute a sequential range of local presets by inserting a colon “
:
” between the
lowest and highest local preset numbers in the BCS command.
If the level designation “
L
” is omitted, the Execute Local Preset command is executed on the
default level, which is normally Level 0.
Multiple levels can be entered in an Execute Local Preset command provided that a local
preset with the same number resides on all the specified levels. For example,
RL1 2P3T
would execute the switch(es) defined as Local Preset 3 on Level 1 and execute the switch(es)
defined as Local Preset 3 on Level 2.
Important:
If the level is not specified in a BCS command, the command is executed on the default
level (normally Level 0), which is defined in the configuration file. If the level is omitted and the
BCS command executes on an unexpected level, check the default level in the configuration file.
Tip:
When you know you will need to disconnect all the switches routed by one or more local presets
(on the same level), an efficient strategy is to create another local preset to do so.
