Introduction to BCS
Introduction to BCS
This instruction manual is designed for programmers who wish to create their own control programs using the BCS
(Basic Control Structure) protocol. BCS is a simple character stream control protocol used by external control devices
attached to a number of AMX products, e.g., Matrix Switchers, the HDMI-UTPRO-0808, and Enova DGX 8/16/32/64
Digital Matrix Switchers. BCS commands are used primarily for control of a matrix switcher during system installation
and setup and for diagnostic purposes. Internally, BCS commands are translated into XNNet protocol packets.
Important: We strongly recommend checking Appendix A (see page 26) for information about BCS
commands specific to your equipment. Not all systems support all BCS commands.
Overview
BCS is a set of alphanumeric characters that combine to form control commands. BCS command strings are entered into
a terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal) running on an external control device. The
control device (AMX control device, PC, or third-party controller) sends the commands to the system. Control devices
must be able to send and receive ASCII code via an RS-232 or RS-422 serial port. (For information on attaching external
controllers, see the “Installation and Setup” chapter of the specific enclosure’s instruction manual.)
BCS commands can also be used for APWeb macros, diagnostics, and Telnet sessions, as well as in AMX software
applications (e.g., APControl).
For advanced programmers who want to design their own control programs can use XNNet protocol. The XNNet API
Communication Library that supports C, Java, and Visual Basic with examples of the XNNet Protocol in use is available
at www.amx.com.
General rules, as well as lists and tables for command string formats and command string responses, are provided first
for quick reference. Detailed information and examples for creating and executing the various commands can be found
in the subsequent chapters. For product specific information, see page 26.
Command String Formats
A command string is a series of command characters and numbers used to send commands to the system.
Commands can include basic ones for executing and disconnecting switches, as well as for verifying the status of
switches. Commands can execute local presets or define and execute global presets. On systems with audio, commands
can be used to control a variety of audio functions depending on the product (e.g., adjustments to tone and balance are
available on the Precis DSP).
In a command string, each character is either a general command (e.g., “D” for Disconnect) or an identifier that indicates
what the following number designates (e.g., “I” and the number following it designate an “input number”).
The command string CL1I27O160T can be interpreted as follows:
[C] Change on [L1] Level 1, [I27] Input 27 to [O160] Output 160, [T] Take to execute the command.
For a complete list of command characters and their functions, see page 7.
Command characters and numbers are echoed back to the terminal screen as the system accepts them. When a command
is successfully executed, all of the characters appear as entered. If a command character or a number is not accepted, the
system responds with a different character and all or part of the command is not executed. For explanations of other
possible responses, see page 8.

Introduction to BCS
General Rules for Using BCS Commands
Command strings typically are not case-sensitive (for exceptions – see “Heritage Systems” on page 36).
All command strings must end with the Take command “T” which tells the system to execute the command.
“O” is the letter O, not the number zero (0)
Entering “X” at any point in a command string cancels the command.
A command cannot be canceled after the “T” has been entered.
Command strings cannot be edited. If a mistake has been made, enter an “X” and then reenter the command.
To specify multiple outputs, inputs, levels, or local presets, enter a space “ ” between each number. Multiple
inputs are only valid in Disconnect commands.
To specify a range of outputs, inputs, or local presets, insert a colon “:” between the lowest and highest
numbers of the range (not supported if the command is otherwise invalid, e.g., cannot specify a range of
inputs in a Change command; the first input only would be routed.).
Colons “:” and spaces “ ” can be used in the same command string.
If the level designation “L” is omitted, the command is executed on the default level, which is normally
Level 0.
* For systems where all of the audio channels are not switched on the same level (e.g., an audio only Optima that routes
8 channels of audio on Level 1 and 16 channels on Level 2), volume and input gain commands for each of the levels
must be entered separately.
Note: Groups of signals (e.g., RGBHV plus stereo) and breakaways of signals (e.g., RGBHV only or stereo
only) are stored in the configuration definition as virtual matrices (VMs). While some methods of control (e.g.,
control panels) use the term “VM”, BCS commands on a serial controller use the equivalent term “level”
designated by an “L”. For the purposes of this document, the terms virtual matrix and level are
interchangeable.

Introduction to BCS
Generating BCS Commands
Important: We strongly recommend checking Appendix A (page 26) for information about BCS commands
specific to your equipment. Not all systems support all BCS commands.
Basic and Preset Commands
To generate basic and preset BCS commands:
1.
Enter commands using the formats from the tables below. Replace the “#”s with the appropriate level, input
(source), output (destination), local preset, or global preset number.
Basic Command Strings
To execute a switch
CL#I#O#T or CL#O#I#T
To disconnect a switch
DL#I#T or DL#O#T
To verify switch status
SL#O#T or SL#I#T
Preset Command Strings
To execute a local preset
RL#P#T

R#T
Digital Output Volume and Digital Input Gain Commands
To use audio commands, your system must contain audio components that support the specific audio commands. The
decibel level resulting from an output volume or input gain adjustment command must fall within the range of the audio
specifications (for a specific audio output volume or input gain adjustment range, see the specifications for that specific
audio board or connector set in the product’s instruction manual). Audio commands can only be executed on levels that
switch audio.
Important: Do not use leading zeros for gain values in audio commands.
To generate digital output volume and digital input gain BCS commands:
1.
Enter commands using the formats from the tables below. Replace the “#”s with the appropriate level and input
(source) or output (destination) number. Replace the “^^^” with the decibel level entered as an integer number
representing the desired decibel value multiplied by 10 (e.g., +8.0 dB is entered as 80 and -40.5 dB is entered
as -405).
Digital Output Volume Command Strings
To adjust volume to a specific (absolute) value
CL#O#VA^^^T
To adjust volume by a specific (relative) amount
CL#O#VR^^^T
To adjust volume up or down a step (increment/decrement)
CL#O#VS+T or CL#O#VS-T
To mute or un-mute the volume of an output
CL#O#VMT or CL#O#VUT
To verify volume status
SL#O#VT
Caution: We strongly recommend that input gain adjustments be made only by a qualified installer or dealer.
Digital Input Gain Command Strings
To adjust input gain to a specific (absolute) value
CL#I#VA^^^T
To adjust input gain by a specific (relative) amount
CL#I#VR^^^T
To adjust input gain up or down a step (increment/decrement)
CL#I#VS+T or CL#I#VS-T
To verify input gain status
SL#I#VT
Note: For information on DSP (Digital Signal Processing) commands, see page 22.

Introduction to BCS
Command String Responses
When command characters are entered into a terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal)
and accepted by the system, they are echoed back to the terminal screen one at a time, as they are typed. The complete
command has executed successfully when all of the entered characters including the entered Take command “T” appear.
If a command character is not accepted, a different character than the one entered appears and all or part of the command
is not executed.
BCS Response Table
The following table shows BCS response characters, with descriptions and meanings, that may appear instead of an
entered character or number. If these characters appear, all or part of the command is not executed.
For troubleshooting strategies when error codes appear, see Appendix B “Error Code Reporting,” starting on page 41.

Executing Switches
Executing Switches
A switch is an active connection between an input (source) signal and one or more output (destination) devices. The
signals connected in a switch command are either individual signals or groups of signals coming through the connectors
on the rear of the enclosure. When executing a switch, you must specify a level that contains all the signals you want to
route (or the switch will execute on the default level, normally 0). Levels are determined in the configuration definition
that has been loaded onto each CPU in the system.
A switch command string begins with the character “C” which initiates a Change command for routing a switch. The
characters and numbers that follow the “C” command tell the system which inputs and outputs to connect on which level.
The last character is the Take “T” command which tells the system to execute the command.
For example, the command string CL0I102O39T can be interpreted as follows:
[C] Change on [L0] Level 0, [I102] Input 102 to [O39]Output 39, [T] Take to execute the command.
For a complete list of command characters and their functions, see page 7.
Command characters and numbers are echoed back to the terminal screen as the system accepts them.
A command has successfully executed when the entered “T” command appears. If a command or number is not
accepted, a different character appears and all or part of the command is not executed.
For explanations of other possible responses, see page 8.
In each Change command, you can enter multiple levels and multiple outputs (destinations), but only one input (source).
To enter multiple levels and outputs, include a space between each set of numbers.
To enter a range of outputs, insert a colon “:” between the lowest and highest numbers of the range.
If the level is not specified in the Change command, the command is executed on the default level, which is normally
Level 0 (e.g., CI72O35T routes Input 72 to Output 35 on Level 0).
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 (for systems without a
configuration file, check the product documentation).
The following instructions provide command string formats for executing switches by designating either an input or one
or more outputs first.
To execute a switch:
1.
Enter the Change command below. Replace the “#”s with the level, input, and output number(s).
CL#I#O#T or CL#O#I#T
Change Examples
BCS Command
CL1I6O24T
CL1I6O2 4 9T

Cancels the incomplete command
Instruction Manual – BCS Basic Control Structure Protocol

Disconnecting Switches
Disconnecting Switches
The characters and numbers in a Disconnect command tell the system which input or output to disconnect on which
level. Command characters and numbers appear on the screen when the system accepts them. A command string has
successfully executed when the entered “T” command appears. If a character or number is not accepted, a different
character appears and all or part of the command is not executed. For explanations of other possible responses, see
page 8.
In disconnect commands, enter multiple levels and outputs or inputs by including a space between each set of numbers.
(You cannot enter multiple inputs and outputs in the same disconnect command.) Enter a range of outputs or inputs by
inserting a colon “:” between the lowest and highest numbers of the range.
If the level is not specified in the Disconnect command, the command is executed on the default level, which is normally
Level 0 (e.g., DO67T disconnects Output 67 on Level 0).
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 (for systems without a
configuration file, check the product documentation).
Caution: Disconnecting an input disconnects all the outputs receiving that source signal.
The following instructions provide command string formats for disconnecting switches by designating either inputs
(sources) or outputs (destinations).
To disconnect a switch:
1.
Enter the Disconnect command below. Replace the “#”s with the level and output number(s) or
the level and input number(s).
DL#O#T or DL#I#T
Disconnect Examples
BCS Command
DL0O8T
DO3T
Action
Disconnects Output 8 on Level 0
Disconnects Output 3 on the default level (defined in configuration file,
normally Level 0)
DL2O3 5:9 11T
Disconnects Outputs 3, 5, 6, 7, 8, 9, and 11 on Level 2
DL2I5T
Disconnects all outputs connected to Input 5 on Level 2
DL3I7 9 15T
Disconnects all outputs connected to Inputs 7, 9, and 15 on Level 3
Instruction Manual – BCS Basic Control Structure Protocol
10
Verifying Signal Status
Verifying Signal Status
Switch status can be checked to confirm that the switch has executed correctly or to confirm correct routing to multiple
outputs. Digital output volume status (see page 18) and digital input gain status (see page 21) can also be verified. The
characters and numbers in a Status command tell the system which input or output to verify on which level. A Status
command has successfully executed when the entered “T” appears followed by the result of the status query in
parenthesis. Empty parentheses ( ) indicate that the input or output specified is not routed on the specified level. For
status response examples responses, see below.
Fragmented status results (see page 12) are available for systems that support this feature. Fragmented Status Reporting
must be enabled in XNConnect before valid fragmented results can be returned (see the XNConnect Help file).
General Rules for Verifying Status
Multiple inputs, outputs, or levels cannot be entered in a Status command.
If the level is not specified in the Status command, the command is executed on the default level, which is
normally Level 0 (e.g., SI83T verifies the routing status of Input 83 on Level 0).
If you check the status for an input or an output on an audio-follow-video level and only the video or the
audio is routed on that level, the result will come back as not routed, unless the system supports fragmented
status reporting.
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 (for systems without a
configuration file, check the product documentation).
To verify signal status:
1.
Enter the Status command below. Replace the “#”s with the level and input number or the level and output number.
SL#I#T or SL#O#T
The results of the BCS command will display in parentheses; empty parentheses ( ) indicate that no input is routed
to the output being verified or that no outputs are receiving a signal from the input being verified.

Verifying Signal Status
Fragmented Status
The system may also support fragmented status reporting. (To determine if your system supports fragmented status
reporting, see Appendix A which starts on page 25.) This feature must be enabled in XNConnect. If reporting is not
enabled, the status result will display empty parentheses: ( ).
When fragmented status reporting is enabled, a fragmented status result is indicated by a ( # ).
The ( # ) or ( ) indicate that either no input is routed to an output or that the full definition of an input is not connected
to the same output.
For example, audio and video signals from Input 5 are routed to Output 9 on the audio-follow-video level (L0) and the
audio from Input 5 is also routed to Output 10 on the audio level (L2).
The results of checking status on Input 5 on the audio-follow-video level (L0) would be
“SL0I5T( 9 10# ).” This indicates that Output 9 is connected on all defined components of Input 5 on
Level 0 and that Output 10 is connected on some, but not all, of the components of Input 5 on Level 0.
The results of checking the status of Output 10 on the audio-follow-video level (L0) would be
“SL0O10T( # ).” This indicates that Output 10 is connected but not receiving all of the components from
an input (Input 5) on Level 0.

Executing Presets
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 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.

normally 0)
RL3P1 2T
Executes Local Presets 1 and 2 on Level 3
RL3 1P1T
Executes Local Preset 1 on Level 3 and Local Preset 1 on Level 1
Global Presets
A global preset is a snapshot of a system’s routing state. The routing state is all routings on all levels (including audio
settings) for all enclosures in a system. Once the system state has been captured with an “RR” Define Global Preset
command, it can then be restored at any time with the “R” Execute Global Preset command. Global presets cannot be
defined in XNConnect.
Note: We strongly recommend keeping track of the numbers and the system state routings used for each
global preset. If another system state is assigned to a previously used number, the former state will
automatically be overwritten.
To define a global preset:
1.
Route the system to the desired state and enter the Define Global Preset command below.
Replace the “#” with the global preset number.

Adjusting and Verifying Audio
Adjusting and Verifying Audio
For BCS purposes, adjustments to input audio signals are referred to as digital gain adjustments, while similar
adjustments to output audio signals are referred to as volume adjustments. Not all systems support digital input gain or
digital output volume control. If your system supports these features, adjustments may be made at any time during
normal operation.
General Rules for Audio
Volume is adjusted using any of the following three methods:
Absolute – adjusts volume to a specific decibel level.
Relative – increases or decreases volume by a specific decibel amount.
Increment/Decrement – increases or decreases volume a step.
An output does not need to be routed to adjust the volume; however, it may be helpful to hear the adjustment.
Audio adjustments can only be executed on a valid level that switches audio signals. If an audio adjustment is
attempted on a level that does not include audio, an error code may be sent out (see page 41).
For systems where all of the audio channels are not switched on the same level (e.g., an audio only Optima
that routes 8 channels of audio on Level 1 and 16 channels on Level 2), volume and input gain commands for
each of the levels must be entered separately.
Output volume adjustments remain in effect when the output is switched to receive a different input or is
switched on a different level (e.g. from audio only to audio-follow-video).
Specify multiple outputs by including a space between each output number. Specify a range of outputs by
inserting a colon “:” between the first and last numbers of the range.
Enter decibel levels as an integer number representing the desired decibel value multiplied by 10. For
example, +5 dB is entered as 50 and -60.5 dB is entered as -605. (Interpret results for a volume status
command in the same way.)
Do not use leading zeros for gain values in audio commands.
When a muted output is un-muted, the output returns to its previously un-muted volume.
When a Volume command is sent to a muted output, the output is automatically un-muted and then the
volume adjustment is applied. When an input gain command is sent to an input connected to a muted output,
the gain is applied to the input and the output remains muted.
The volume range of an output is determined by the audio board/connector. For a specific audio volume
range, see the specific board/connector documentaion. If the requested volume change results in a decibel
level outside the range specified by the board/connector, the system responds with “X” indicating that an
invalid value was entered.
The total through-system gain (the amount of input gain plus the amount of output gain) for any input to
output routing path is automatically limited by the matrix switcher. (For the value of through-system gain and
other audio specifications, see your matrix switcher’s instruction manual.) If a volume command is entered
that exceeds the matrix switcher’s specifications, the command will be accepted (and will be indicated in
status results) but will not result in an audible difference if the dB value entered is outside of the matrix
switcher’s audio range.


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 (for systems without a
configuration file, check the product documentation).

Adjusting and Verifying Audio
Adjusting Digital Input Gain
For BCS purposes, adjustments to input signals are referred to as digital gain adjustments, while similar adjustments to
output signals are referred to as volume adjustments. Not all systems with audio support digital input gain adjustments.
Although digital input gain is normally set during installation, if your system supports digital input gain control, gain
adjustments can be made at any time during normal operation. Digital input gain range is -10 dB to +10 dB. Inputs
cannot be muted.
Digital input gain should be adjusted as part of system setup. If adjusting input gain, we recommend doing so before
making any output adjustments.
Caution: We strongly recommend that input gain adjustments be made only by a qualified installer or dealer.
The purpose of controlling the input gain (the nominal level of the signal from the source device) is to allow source
signals of various amplitudes to be equalized before they are routed and the volume is adjusted. Equalizing source levels
provides a consistent reference for volume adjustments and eliminates jumps when routing a new input to an output.
Typical uses for input gain include switching consumer and professional grade audio equipment (whose levels can vary
noticeably) in the same routing system. Input gain adjustment is also used for equalizing amplitudes between balanced
and unbalanced inputs.
Note: The total through-system gain (the amount of input gain plus the amount of output gain) for any input to
output routing path is automatically limited by the matrix switcher. (For the value of through-system gain and
other audio specifications, see your matrix switcher’s instruction manual.) If a volume command is entered
that exceeds the matrix switcher’s specifications, the command will be accepted (and will be indicated in
status results) but will not result in an audible difference if the dB value entered is outside of the matrix
switcher’s audio range.
The following section describes three methods used to adjust digital input gain as part of the process of equalizing input
levels. We recommend routing an input before adjusting its gain; although not necessary, it can be helpful to hear the
adjustment.
To adjust digital input gain use any of the following three methods:
Absolute – adjusts input gain to a specific decibel value
Relative – adjusts input gain by a specific decibel amount
Increment/Decrement – adjusts input gain up or down a step
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 (for systems without a
configuration file, check the product documentation).
To adjust inputs to equalize source levels:
1.
Route an input (source) to the first output (destination).
2.
Adjust the digital input gain for the input to the desired dB level by using one of the three methods on the following
two pages.
3.
Repeat Steps 1 and 2 for additional inputs that will be routed to the same output.

Adjusting and Verifying Audio with DSP
This chapter covers information unique to products with Digital Signal Processing (DSP) functionality. For information
on general audio functions, see “Adjusting and Verifying Audio” on page 15.
AMX products with DSP use BCS commands to make volume adjustments at anytime during normal operation. Balance
and tone can also be adjusted at any time using BCS commands.
Equalization bands (see page 24) and digital input gain (see page 18) should be adjusted during system setup.
Caution: We strongly recommend that input gain adjustments be made only by a qualified installer or dealer.
If adjusting input gain, we recommend doing so before making any output adjustments.
General Audio Rules for Products with DSP
Volume is adjusted using any of the following three methods:
Absolute – adjusts volume to a specific decibel level (see page 16).
Relative – increases or decreases volume by a specific decibel amount (see page 16).
Increment/Decrement – increases or decreases volume a step (see page 17).
An output does not need to be routed to adjust the volume; however, it may be helpful to hear the adjustment.
This also applies to adjusting input gain.
Enter decibel levels as integer numbers representing the desired decibel value multiplied by 10. For example,
+5 dB is entered as 50 and -60.5 dB is entered as -605. (Interpret volume status results in the same way.)
Do not use leading zeros for gain values in audio commands.
If the requested volume change results in a decibel level outside the valid range for that particular audio
component, the system responds with an “X”.
When a muted output is un-muted, the output returns to its previously un-muted volume.
When an output volume command is sent to a muted output, the output is un-muted and then the volume
adjustment is applied.
Inputs cannot be muted.
When an input gain command is sent to an input connected to a muted output, the gain is applied to the input
and the output remains muted.
To cancel an incorrect or incomplete command, enter “X”.

* Error code reporting displays a seven-digit code (e.g., EFF8002) when a command string is entered and not accepted.
This code is in addition to (or instead of) the single character that displays when an error is in a command string.
** Not all models of this product family support this command; to determine which models do, see the specific product
section in this appendix.
If you have any questions regarding which features are supported by your system, record the system serial number(s),
determine the Application Code version (see below), and contact technical support (see page 43).
Application Code Version
Important: We recommend determining which Application Code version your enclosure uses; full support of
some BCS commands depends upon the Application Code version. Most of the heritage systems do not
support the ~scr! command to display a splash screen. To determine the Application Code version for these
systems, before applying power, attach a PC to the enclosure’s serial port with a null modem serial cable.
Open a terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal) on the PC and power up the
system. View the display in the terminal emulator for system information including the Application Code
version.
To determine the system’s Application Code version:
1.
View the long splash screen by entering ~scr! (see the table above for products that support Diagnostic
commands and enter ~scr1v3!) into the terminal emulator.
The “Hardware Driver” is the enclosure’s Application Code version.
To determine if the Application Code version displayed supports the relevant BCS command, see the applicable
section for your system in the following pages.

Appendix B – Error Code Reporting
Appendix B – Error Code Reporting
When a command string is entered but not accepted, a different character than the one entered will appear. All of the
AMX systems listed in the “Product Specific” Appendix support limited error code reporting (displaying a single
character). Advanced systems support error codes numbers (alone or in addition to a single character) if the error code
reporting is enabled.
Limited Error Codes; Error Code Numbers and Prefixes
Limited Error Codes
If a “?” appears instead of the command character or number you entered, the system did not understand the command
because the command string format contained an error (e.g., not indicating an input in a Change command).
If an “X” appears instead of the command character or number you entered, the system understood the command, but did
not execute all or part of the command. For example, an “X” may appear when entering an invalid value (such as Output
272 in a system that only has 256 outputs) or requesting a volume setting which results in a decibel level that is outside
of the range for the board / connector set.
Precis LT only – If an “E” appears instead of the command character or number entered in a Status command, a
communication failure occured between the CPU and the control panel.
Troubleshooting
When error code reporting is enabled, error codes can appear in a terminal emulation program (e.g., TeraTerm, PuTTY,
or HyperTerminal).
When you are using BCS commands, one common troubleshooting strategy is to enter the command again. Often the
command has simply been entered incorrectly (e.g., omitting an output in a Change command). In other cases, the
command has specified a value that is not valid.
When you are using an external controller, one of the most common troubleshooting strategies is to resend the command
to see if the error was simply a time out error.
Error Code Numbers
In systems that support error code reporting, an error code number beginning with E# or W# will be displayed in addition
to the command string with a ? or x. In some systems, the error code will appear alone. Sometimes error codes appear if
the system’s status changes, even though a command string was not entered.
This following section provides an overview of common error codes that can appear for systems when this feature is
enabled.
Error Code Prefixes
First letter of the code indicates:
E – Error
W – Warning
A – Alarm*
I – Information*
* Because these codes very rarely appear, they are not included in the table on the following page.
For systems that support system error code reporting, the default is error code reporting disabled. We recommend
enabling error code reporting when a command string response contains the characters
“?” or “X”, when troubleshooting the system, or when directed by technical support.
Instruction Manual – BCS Basic Control Structure Protocol
41
Appendix B – Error Code Reporting
Enabling Error Code Reporting
Error code reporting can be enabled or turned off with BCS commands entered into a terminal emulation program.
To enable error code reporting:
1.
Enter $ERR=1!
The system responds with V.
Note: If the power is cycled, you will need to enable error code reporting again.
To turn off error code reporting:
1.
Enter $ERR=0!
Common System Error Codes
The table below lists the error code, the name of the code, the meaning of the code, and some basic troubleshooting
strategies. This list is not intended to be comprehensive, nor does it apply to all products. If an error code appears that is
not listed, note the specific number and contact technical support (see page 43).

Technical Support
If this manual has not satisfactorily answered your questions regarding BCS commands, please contact your AMX
representative or technical support. Have the system’s serial number ready. The system’s serial number is normally
located on the rear of the enclosure.
We recommend recording the system’s serial number in an easily accessible location.

for System Diagnostics
System Component Information
Some of the AMX systems listed in the “Product Specific” Appendix display system information in a splash screen* for
diagnostic purposes (see the individual product in the table on page 27 to determine if your system supports diagnostic
commands). The information indicates the current status and well-being of the system components.

The system’s component identity numbers are
to the left of each component
FIG. 2 Example of a default Epica DG splash screen
The splash screen can be accessed using a terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal).
One of four verbosity** settings is specified to provide a level of detail for information on up to seven system
components. Only one verbosity setting and one component identity setting can be entered in a command. The order in
which the verbosity and component identity settings are entered is interchangeable. For the number of components a
system supports, see the individual product in “Appendix A – Product Specific BCS Commands” starting on page 25.
Note: In a multi-enclosure system, the splash screen displays information only for the enclosure that is
connected directly to the PC.
* AMX reserves the right to add to the contents of the splash screen at any time, without notice.
** Verbosity (i.e., wordiness) refers to the amount of information provided; the higher the verbosity setting, the more
information is displayed.
Instruction Manual – BCS Basic Control Structure Protocol
45
Appendix C – Programmer’s Interface for System Diagnostics
Verbosity Settings
The verbosity (v) settings (v0, v1, v2, v3) correspond to the level of detail that will be displayed, with v0 being the
lowest level of detail and v3 being the highest level.
Component Identity Settings
Detailed information for a single system component can be specified (if the system supports it) by using its identity (i)
number setting (i1 through i7) in the following table. Minimal information for all supported components can be
specified by using the identity number i0.

Note: For the number of components that individual products support, see “Appendix A – Product Specific
BCS Commands” on page 26.
Default Settings
At system boot, the ~scrv0i1! setting is displayed.
If the verbosity setting is omitted, the verbosity level will be the lowest (v0).
The component setting must be included; otherwise, entering any of the verbosity settings alone will result in
a display equivalent to v0i0.
If both settings are omitted during a query (~scr!), the information displayed will be at the lowest verbosity level for
all components (v0i0) (FIG. 2 on page 45).
Instruction Manual – BCS Basic Control Structure Protocol

Appendix C – Programmer’s Interface for System Diagnostics
Using BCS to Access System Diagnostic Information
Instructions are provided for accessing the lowest level of verbosity for all components and for accessing a specific level
of verbosity for a specific component.
To access the lowest level of verbosity for all components:
1.
Enter ~scr! or ~scrv0i0!
Note: Either of these commands provides a “menu” of the identity numbers and their corresponding
components (FIG. 2 on page 45).
Only one verbosity setting and one component setting can be entered in a command. The order in which the verbosity
and component identity settings are entered is interchangeable.
To access a specific level of verbosity for a specific component:
1.
Enter ~scr (to access the splash screen).
2.
Enter the verbosity level setting v# and the component’s identity setting i#.
Either may be specified first.
3.
Enter ! (to send the command).
