DM84 ADFE Commands

adfeen Automatic digital feedback elimination enable
adfefil Automatic digital feedback elimination filter deployment

Termination: all commands are terminated with an ASCII carriage return character (hex code 0x0D), represented by <CR> in the examples below. All responses are terminated with an ASCII carriage return, line feed pair (hex codes 0x0D, 0x0A), represented by <CRLF> in the examples below. An ellipsis (...) represents members of an array that have been omitted from an example for the sake of brevity.

Verbose response: commands prefixed with an exclamation point (bang) character result in a "verbose" response containing the name of the property or action being addressed, along with the current values of the property in question. Property values are always returned in the "assignment" form, for example outmt(2)=1. This supports certain 3rd party control programming styles where the response to all responses needs to be self-describing and/or contain current property values.

Examples:

REQUEST

COMMAND

!store(3)<CR>

OK store(3)<CRLF>
COMMAND

!run={1,3,5}<CR>

OK run={1,3,5}<CRLF>
QUERY

!outgn(3)?<CR>

OK outgn(3)=0<CRLF>
QUERY

!outmt(*)?<CR>

OK outmt(*)={0,1,1,0}<CRLF>
UPDATE

!ingn(3)=0<CR>

OK ingn(3)=0<CRLF>
UPDATE

!outmt(*)={0,1,1,0}<CR>

OK outmt(*)={0,1,1,0}<CRLF>

 

adfeen (adfe enable)

This command may be used as a query to read the adfe enable status, or as an update to set the status. The audio input channel is specified by using the address syntax. Addresses must be in the range 1 to 8. The data type is integer, either "1" meaning that the adfe feature is enabled, or "0" meaning that it is not.

Examples:

REQUEST

RESPONSE
QUERY

adfeen(2)?<CR>

OK 1<CRLF>
UPDATE

adfeen(7)=0<CR>

OK<CRLF>

 

adfefil (adfe filter deployment)

This command may be used as a query to read the adfe filter deployment status, or as an update to deploy an adfe filter. The input channel and filter index are specified by using the 2 dimensional address syntax. Addresses for the first dimension (input channel) must be in the range 1 to 8. Addresses for the second dimension (adfe filter index) must be in the range 1 to 6. The data type is integer, unless the adfe filter index is wildcarded, in which case the data type is an array of integer of size 6. This is allowed for queries only. The data values are in the range 0 to 95, where 0 means that no filter is deployed, and the others represent adfe filters covering the frequency range 105 to 9773 Hz. See the table below.

Examples:

REQUEST

RESPONSE
QUERY

adfefil(3,2)?<CR>

OK 0<CRLF>
QUERY

adfefil(5,*)?<CR>

OK {12,0,0,0,0,0}<CRLF>
UPDATE

adfefil(4,1)=15<CR>

OK<CRLF>
