Overview

E Desk can be controlled via the control dialogs in the E Desk software, or via
third-party controllers using RS-232 or Telnet.

For control of E Desk, Whirlwind created ETP (E Desk Text Protocol). This
simply means that E Desk will accept strings of ASCII characters to control and
read settings of gain, mute, logic state, frequency, audio levels, and other
parameters of DSP Blocks in E Desk products.

ETP strings can be sent via third-party controllers using RS-232 (see page 4) or
Telnet via TCP/IP (see page 5). A line feed needs to be sent after each
command string sent.

The ETP strin g is structured in the following order: Command DeviceNumber
Attribute InstanceIDNumber Index1 Index2 Value <LF>

ETP strings require a space between each parameter; the last character in the
string needs to be a line feed <LF>.

For each control string a few components will need to be derived from the E
Desk software: Device Number, InstanceIDNumber, and Index. Command and
Attribute are derived from this document. In a SET command, Value is used to
specify what the DSP block attribute is to be set to. In an increment or
decrement (INC or DEC) command Value is used to specify how much the DSP
block attribute is to be changed by.

**Note** E Desk software will assign an Instance ID to each DSP block on the
initial compile of the system. Subsequent compiles will not change the Instance
IDs unless the “Reassign Instance IDs” check box is selected in the ‘Compile’ tab
of the ‘Options’ screen (located on the Tools pull-down menu) in the E Desk
software.

Example: A string to control a fader might look like this:
SET 1 FDRLVL 2 1 9 <LF>. The individual components for this string are:

Command Device

Number

Attribute

Instance
ID
Number

Index1 Index2 Value Line

feed

SET 1 FDRLVL 2 1 9 <LF>

Notice that Index2 is not used since there is nothing entered in this parameter.

Notice that Index1 is not used since there is nothing entered in this parameter.
Example: A string to turn up a cross point on a matrix mixer might look like this:

INC 2 MMLVLXP 4 3 2 1 <LF> The individual components for this string are:

Command Device

Attribute

In this example Index1 and Index2 are both used, together they specify which
cross point is to be changed.

RS-232 Control

The RS-232 port on the back of an E Desk unit is set to a default baud rate of
38400, 8 data bits, no parity, 1 stop bit, and no flow control. (38400:8:None:1). If
multiple E Desks are connected together in a system then only one RS-232 port
needs to be connected to a third-party control system; communication data is
shared via Ethernet through a switch.

When controlling multiple E Desk units that are not part of the same DAP file,
each E Desk unit will need to be addressed via its own RS-232 port from a
control system or PC. E Desk units cannot be linked together via RS-232, like
some other WHIRLWIND Advantage products can.

(The RS-232 baud rate can be set to 9600, 19200, or 38400 – default is 38400)
A straight through PC Serial Cable is used to communicate from an RS-232 port

on a third-party controller (or PC*) to the RS-232 port located on the back of an E
Desk unit.

(* A PC can be used with a terminal emulator program, such as HyperTerminal
etc, to send/receive ETP Strings…E Desk software must be connected via
Ethernet in order to communicate.)

4

Telnet Control

E Desk can be controlled using Telnet via TCP/IP. The same command strings
that are used for RS-232 Control are used for Telnet.

When controlling multiple E Desks that are not a part of the same DAP file, each
E Desk device will need to be addressed via its own Telnet session from a
control system or PC.

ETP String Component: Command

SET – Tells E Desk that a DSP attribute is to be set to a specific value – may
contain negative numbers and/or decimal points
GET - Tells E Desk that a DSP attribute is to be read – Response may contain a
decimal point and/or a negative number.
INC - Tells E Desk that a DSP attribute is to be incremented by a specific amount
DEC- Tells E Desk that a DSP attribute is to be decremented by a specific
amount
RECALL – Tells E Desk that a preset is to be recalled.

SETL and GETL can be used if negative numbers and/or decimals are not
supported by a control system.

SETL – Tells E Desk that a DSP attribute is to be set to a specific value, no
decimal places or negative numbers –To convert a dB number: add 100 to the
desired level and then multiply by 10.

Example: To set a level to –60.5dB, add 100 (-60.5 +100 = 39.5). Then
multiply by 10 (39.5 X 10 = 395). Instead of Value being –60.5, Value
after this SETL command will equal 395.

GETL - Tells E Desk that a DSP attribute is to be read without negative numbers
or decimals. To convert this number to dB: divide the number by 10, then
subtract 100.

Example: With a returned GETL response of 405, divide by 10 (405 / 10 =

40.5), and then subtract 100 (40.5 – 100 = -59.5dB)

For your reference, the SETL/GETL Table on the following page shows .5dB
increments converted into the SETL/GETL format.

Some Attributes do not support all commands. The Attribute section defines
which commands support SET/SETL, GET/GETL, INC, or DEC functions.
RECALL is only used on preset commands.

*When GET or GETL is used, a Value will not need to be specified since
GET/GETL is a request command. A Value must be specified in order for strings
with SET/SETL, INC, DEC, and RECALL to work.

number

DSP block with

An E Desk Device Number represents the physical E Desk box’s defined
address. The E Desk software automatically sets this number when a system is
Compiled and loaded.

The Device number that a DSP block has been assigned to can be determined in
3 ways:

First Way:

1) Right click on the DSP block and select ‘Properties’.

2) Click on DSP 1 attributes tab and scroll down. The device that the block is assigned to
will be displayed in the ‘Allocated To Unit’ field.

*Note: Each DSP block can be assigned to a device by changing ‘Fixed In to Unit” to ‘Yes’
(this is defaulted to no).

Second Way:

1) In the Display tab of the Options screen select “Display Device Assignment in

DSP Block info field”.

2) This will display the device that each DSP block is assigned to on the main

screen.

Device number

Third Way:

1) While connected an E Desk’s RS -232 port, type the string; GET 0 DEVID E
Desk will return the Device Number of the unit you are connected to.

ETP String Component: Attribute

The Attribute defines the portion of the DSP block to be controlled (fader level,
crosspoint mute etc). The following tables show whether each ETP Attribute supports
SET/SETL, GET/GETL, INC, and DEC Commands, as well as the Value range that the
Attribute will accept. Index1/Index2 determines whether Index1, Index2 or BOTH are
needed for a ETP String to be complete.

ETP Strings can address:

Input/Output Blocks
Mixer Blocks
Equalizer Blocks
Filter Blocks
Crossover Blocks
Dynamic Blocks
Routers
Delays
Meters
Generators

ETP String Component: Instance ID Number

E Desk uses an instance ID number to specify the exact DSP block to be controlled.
Right click on the DSP block and select “Properties”, the instance number can be found
the DSP Attributes 1 tab.

The property sheet can only be accessed
in an offline screen.

**Note** E Desk software will assign an Instance ID to each DSP block on the initial
compile of the system. Subsequent compiles will not change the Instance IDs unless
the “Reassign Instance IDs” check box is selected in the ‘Compile’ tab of the ‘Options’
screen (located on the Tools pull-down menu) in the E Desk software.

If one or more DSP blocks are disconnected from the audio path (when connections are
not made to at least one input or output) the Instance IDs will be unassigned. New
Instance ID(s) will be reassigned once the DSP block(s) are properly connected again.

26

ETP String Component: Index

Index refers to inputs, outputs, or crosspoints of an Attribute. Some Attributes
will need an Index1 (Input or Row) and/or an Index2 (output or Column). The
tables in the Attribute section will define which, if any, indexes are required for
the string.

Example: INC 1 AMLVLIN 4 1 1<LF>
In an Automatic mixer on device 1 we are increasing the level of input 1 on

instance ID 4 by 1dB. Index1 is used to represent the input number.

Example: DEC 2 AMLVLOUT 6 1 2<LF>
In an Automatic mixer on device 2 we are decreasing the level of output 1 on

instance ID 6 by 2dB. Index2 is used to represent the output number.
Example: SET 1 MMLXP 5 1 2 –5<LF>

In a matrix mixer on device 1 we are setting cross point 1:2 (row 1, column 2)
level to –5dB on instance ID 5.

Note for commands with 2 Index fields, Index1 is the row, and Index2 is the
column.

27

ETP String Component: Value

Value determines what a DSP block is being set to, incremented by, or decremented by.
The Attribute section will define which type of value the string will need in order to
execute the ETP string.

Example: INC 1 AMLVLIN 4 1 1<LF>
In an Automatic mixer input level string, the Value equal to 1 states that the fader is to

be incremented by 1 dB.
Example: SET 2 MMLVLIN 5 2 –100<LF>

In a matrix mixer input level string, the value is set to –100dB.
Example: RECALL 1 PRESET 1004<LF>

For a preset recall we are telling device 1 to recall the fourth preset.
*When GET is used, a Value will not need to be specified since GET is a request

command. A Value must be set in order for SET, INC, DEC, and RECALL command
strings to work.

Example: GET 4 MMLVLOUT 5 <LF>
We are asking the level of a matrix mixer’s output. There is no Value required for this
string.

28

Responses

When a successful SET, SETL, INC, DEC, or RECALL command is sent to an E Desk
device via RS-232 or Telnet, E Desk will respond with: ‘+OK’ followed by a carriage
return and line feed.
Example: Sending the string: SET 2 AMLVLIN 4 2 1< LF> will result in an:
+OK<CR><LF> response.

A successful GET or GETL command will result in a numerical response to the
command string followed by <CR><LF>.

The response from an ETP string with a GET command may contain a decimal
point (with 4 numbers after the decimal) and/or negative numbers, depending on
type of Attribute addressed. If the control system does not support negative
numbers or decimal places a GETL command may be used instead (see page

6).

Example: After sending the above example to an E Desk device the string:
GET 2 AMLVLIN 4 2<LF> would result in the response: 1.0000<CR><LF> this tells us
that the level is currently set to 1dB.

If an incorrect command string is sent, an E Desk will respond with: -ERR <CR><LF>

29

Control Dialog - Overview

E Desk software can be used to control E Desk units real time via a network. After
connecting to an E Desk device, users, technicians, and designers (as determined by
passwords) can access their appropriate level of control of the system. Depending on
the authorized access level of control Levels, Meters, Presets, and layers can be
accessed and changed.

Level Controls, Meters, and, Preset control dialog screens can be minimized and
arranged to provide a simple, and intuitive, user interface for the system. Connecting E
Desk’s Ethernet port, through a switch, to network jacks in various locations can provide
control to the system from different locations via a Laptop or Desktop computer.

*Note – E Desk’s control network can be easily shared on an existing network without
compromising network bandwidth, but CobraNet data should be routed on its own
network to ensure CobraNet audio and existing network reliabilit y.

30

Control Dialog - Levels

Once level controls are placed in a signal path audio levels can be increased,
decreased or muted as needed.

31

Control Dialog - Presets

Once Presets are created, Preset buttons can be placed on screen and used to easily
recall different scenarios.

32

Control Dialog - Meters

If meters are placed on screen, users can view real time Signal Present, RMS, and
Peak indications.

33

HyperTerminal

HyperTerminal is a useful tool that comes with Windows and can be used for RS-232
purposes. Simply open a HyperTerminal session by going to: Start> Programs>
Accessories> Communications> HyperTerminal. Enter a name for your connection and
click ‘OK’. Under the pull-down menu labeled ‘Connect Using’ select the location of
your RS-232 Comm. port.

Under the Comm. port properties set it to 38400, 8, None, 1, and None as shown below.
Now HyperTerminal is ready to use. E Desk does not echo characters typed, so if you
want to view what is being typed into E Desk, click on “echo typed characters locally” in
the ASCII setup screen

34

IP Address Commands

E Desk has some useful IP and reset tools that may be useful when returning to older
systems for service work.

E Desk will automatically output its IP Address through the RS-232 port when it is
powered up and functioning. Simply have a straight through RS-232 cable connected to
E Desk and a PC with HyperTerminal running. When E Desk is powered up it will print
the data in the HyperTerminal screen.

Get/Set IP Address

By typing ‘GET 0 IPADDR<LF>’ in HyperTerminal E Desk will reveal the IP Address it
is set to. Substituting the ‘0’ for a 1, 2, 3, etc will tell E Desk to reveal the IP Address for
the device who’s number is 1, 2, 3 etc. A ‘0’ asks for the IP Address of the E Desk you
are currently connected to. Note: You can only use a 1, 2, 3 etc if there is a system
loaded into the E Desk’s. If it is a single device system, the only device number will be

1.
If an E Desk does not have a system loaded into it, you can set the IP Address via the

RS-232 port. Example: SET 0 IPADDR 169.254.1.200<LF>. If there is no DAP file in
the E Desk, and the command is typed correctly, E Desk will send back a ‘+OK’
response. You will need to power cycle the E Desk for the new IP Address to take
effect. As stated above, E Desk will output the IP Address when powered up, or you
can use the GET I PADDR command mentioned above.

Reset

In rare instances it may become necessary to reset the E Desk device. A reset can be
accomplished through the device maintenance screen, and this is the desired method
for a reset. However, there is a reset command available via the RS-232 port. Simply
type: CLEAR 0 DEVCONFIG<LF> and the device will be reset.
