Instruction Manual – BCS Basic Control Structure Protocol
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., AutoPatch Matrix
Switchers, the HDMI-UTPRO-0808, and Enova DGX 8/16/32 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 25) 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 (such as Windows
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 AutoPatch software applications (e.g., APControl).
For advanced programmers who want access to the underlying XNNet packet based protocol, the
AMX AutoPatch CD (that ships with each system) includes the XNNet Communication Library. This
interface library supports C, Java, and Visual Basic and has examples of the XNNet Protocol in use.
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 25.

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 4.
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 5.

Instruction Manual – BCS Basic Control Structure Protocol
General Rules for Using BCS Commands
Command strings typically are not case-sensitive (for exceptions – see “Heritage Systems”
on page 37).
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.

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:
Enter commands using the formats from the tables below. Replace the “#”s with the appropriate
1.
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
To adjust volume by a specific (relative) amount
To adjust volume up or down a step (increment/decrement)

Command String Responses
When command characters are entered into a terminal emulation program (such as 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

Executing Switches
6
Instruction Manual – BCS Basic Control Structure Protocol
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 4.
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 5.
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:
Enter the Change command below. Replace the “#”s with the level, input, and output number(s).

Instruction Manual – BCS Basic Control Structure Protocol
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 5.
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.
Disconnecting Switches
The following instructions provide command string formats for disconnecting switches by designating
either inputs (sources) or outputs (destinations).
To disconnect a switch:

Enter the Disconnect command below. Replace the “#”s with the level and output number(s) or
the level and input number(s).

Disconnects all outputs connected to Inputs 7, 9, and 15 on Level 3
Verifying Signal Status
8
Instruction Manual – BCS Basic Control Structure Protocol
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 15) and digital input gain status
(see page 18) 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 parenthesis (
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 9) 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 (

input is routed to the output being verified or that no outputs are receiving a signal from the input
being verified.

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

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(

Executing Presets

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.

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
12
Instruction Manual – BCS Basic Control Structure Protocol
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).

Instruction Manual – BCS Basic Control Structure Protocol
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:
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 12.
AMX AutoPatch 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 22) and digital input gain (see page 16) 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 13).
Relative – increases or decreases volume by a specific decibel amount (see page 13).
Increment/Decrement – increases or decreases volume a step (see page 14).
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”.
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 Balance
Note: The examples below assume a default level which is audio or includes audio. If the default
level does not include audio, you must enter a level that includes audio.
Balance commands tell the output to pan to the left or to the right by a percentage of the total range.
Positive percentages pan to the right, and negative percentages pan to the left.

Adjusting Tone
Tone bands (filters) for bass and treble can be adjusted to a specific decibel level at anytime during
normal operations. Each tone band has a range of -12 dB to +12 dB. Further frequency adjustments can
be made to each output by adjusting the equalization bands (see page 22).

Adjusting Equalization Bands
BCS commands can be used to adjust the gain of each EQ band for each output to a specific decibel
level. Each equalization band is identified by its center frequency and spans one octave (see the chart
below for frequency to band number correspondence). The bands are set for a flat response at the factory.
The adjustment range is -12 dB to +12 dB.
Multiple bands can be entered in the same command by including spaces or commas between the
EQ band numbers. When adjusting multiple bands in the same command, an “E” and a list of the bands
is entered first, followed by a “G” and a list of the corresponding gain settings. The number of gain
settings must be equal to the number of bands.
To adjust equalization bands for an output:
Enter the following command string. Replace the “#”s with the output number(s) and equalization

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 HyperTerminal (or other terminal emulation
program) on the PC and power up the system. View the display in HyperTerminal for system
information including the Application Code version.
To determine the system’s Application Code version:
View the long splash screen by entering ~scr! (see the table above for products that support
1.
Diagnostic commands and enter ~scr1v3!) into HyperTerminal.
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.

Instruction Manual – BCS Basic Control Structure Protocol
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 (such as
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.
Appendix B – Error Code Reporting
42
Instruction Manual – BCS Basic Control Structure Protocol
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:
Enter $ERR=1!
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:
Enter $ERR=0!

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 26 to determine if
your system supports diagnostic commands). The information indicates the current status and well-being
of the system components.
FIG. 2 Example of a default Epica DG splash screen
The splash screen can be accessed using a terminal emulation program, such as 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.
Appendix C – Programmer’s Interface for System Diagnostics
46
Instruction Manual – BCS Basic Control Structure Protocol
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.
ComponentIdentity Number

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).
