ACKNOWLEDGMENT
MODE
If acknowledgment mode is enabled, the EF1210 will acknowledge each command it
receives by repeating the status of the command that was sent. This may be used for
verifying that each command is received and recognized by the EF1210. When
acknowledgment mode is turned off, the remote control device can always request the
status of a parameter by sending a query command, such as NC?. When acknowledg-
ment mode is enabled, a query command only generates one message in response.
For example, when you send NC?, you don’t get NC? back in addition to the status of
the noise cancellation feature.
Since acknowledgment mode reports the status of the command rather than simply
echoing back the command, you get a verification that the command had the effect
you thought it would. For example, a command that toggles a parameter will give
you the new on or off status, rather than just echoing the toggle command.
The factory default setting for ACKMOD is 1 (on).
Remote Commands
The following commands can be sent by the remote control device to enable or dis-
able acknowledgment mode.
EF1210 Messages
