Active loudspeaker set
Configuration settings:
SELECT is input source selection, a possible command could look
like this: “ Set select AB<CR> ”. In this case, both inputs A and B will
be mixed together by the SDQ5PIR unit. Possible values are A, B, AB
or WI. WI is the local input of the optional wall control
IPGAIN is input gain. Each source input has its own gain setting
so the source (A, B or WI) needs to be specified. The value can be
between 0 and 3 in steps of 1. One gain step corresponds to 3.75
dB. If an invalid value is used or no source is specified, “
ERROR:
Value Invalid!<CR>
” will be replied. Otherwise, the reply will be
“
Command Executed!<CR>
”
A command to set the input gain of source A to 1 looks like this:
“
SET IPGAIN A 1<CR> ”
AUPTRG : auto power trigger level. Range from 0 to 30. Higher
values will increase the trigger level.
RS232 settings:
All RS232 settings are binary values, they can be ON or OFF.
If ECHO is on, all received characters are echoed back. This can be
handy when programs like hyperterminal are used.
LF is Line Feed. Line Feed is an ASCII character (0x0A) which is
sometimes used to let the cursor jump to the next line. SDQ5PIR
always omits the line feed character. However, when LF is on, there
will be put <LF> character behind each <CR> character. This is
both the case for echoing as for messages sent by SDQ5PIR. Please
take a look to following example: in both cases, the user sends the
following string: “
GET SDQLVL<CR> ”.
