This command turns off reporting of one or more output events. It follows similar syn-
tax.

disable DumpTrig<LF>
tells PDM to stop reporting that DUMP has been
activated.
••
disable DumpTrig Muted<LF>
turns off reporting for both functions.
••
disable ALL<LF>
turns off any message reporting.

affects only the serial messages. Parallel GPIO functions on the DB-25 aren’t
changed, and stay as you set them on the front panel or via Web interface.
Data Delays
PDM can delay two data streams such as PAD (Program Associated Data), to keep it in
sync with audio. This way, you can make sure “now playing” or other information on
RDS receivers or web streams lines up with program audio. When this feature is turned
on, incoming data is stored for exactly the same amount of time that PDM is delaying
audio, and then sent out.
As audio delay is slowly built or collapsed to return to real-time, each data delay is auto-
matically changed to match. If PDM is put into Bypass mode, data passes straight
through.
If you press
DUMP
while Data Delay is on, stored data gets sent out immediately. This
guarantees that important information isn’t lost when audio has been removed.
There are two separate data delays, Data Stream A and Data Stream B, so you can han-
dle both internal cueing information and PAD for listeners. Inputs and outputs for each
can be RS-232 or IP; IP inputs and outputs can have different addresses and ports, and
can function as client or server. You can mix these types for maximum flexibility.
These choices all appear on the
CONFIGURATION
page, in the
Delayed Data Streams
section (page 36). Only one input can feed data at a time, but multiple devices can be
listening to delayed data on the outputs.
