Serial / Parallel Remote control
In addition to IP based remote control, PDM supports traditional control systems for
maximum flexibility. All can be used simultaneously.
Parallel (GPIO or ““Contact Closure””) Control
There are eight inputs and eight outputs for remote control on a rear panel female DB-
25 connector. Each can be assigned to PDM functions through a configuration screen,
described on page 27. Multiple inputs or outputs can be assigned to the same function
if you need isolated circuits. Inputs and outputs are opto-isolated, active low; wiring de-
tails are on page 52.
Serial Control
PDM’s serial control options let you build custom interfaces, such as for an on-air or
logging systems. You can access PDM’s internal control language via RS-232 serial, a
network Web browser, or both at the same time.
The comprehensive language uses abbreviations to query delay depth and internal
temperature, access all GPIO functions, and continuously report PDM’s operating
status.
Standard serial or IP-based connections
Data and control lines appear on a male DB-25 connector in both RS-232 and RS-485
formats, as well as over a network.
