The control module monitors each DSP module for proper operation. Through the use
of a computer interface, the Control Module offers three key functions for monitoring
and upgrading the DSP-8200d.
They include:
• Fault Detection
• Diagnostics
• Reprogrammability
In the event of a DSP module failure, an audible alarm will alert the operator that a
problem has occurred. To assist in identifying the failed module, the heartbeat indicator
will blink at 4 times the normal rate. In addition, the BNC connector will go into fault
position.
A relay switch closure output (BNC connector) is provided which will indicate if power
has been lost to the DSP-8200d as well as an individual module failure. This output may
be configured (via shorting jumper) as either normally open or normally closed.
Operators can connect the DSP-8200d to a standard terminal program using a RS-232
or USB cable. One such common terminal program that is included in all Windows
Operating Systems since Windows 95 is HyperTerminal.
To access the Control Module using HyperTerminal, hook up the terminal program and
hit the 'Esc' key. To access a list of commands available, press the '?' key. While many of
the commands are specific to programming and updating, two commands will be useful
for system status and diagnostic purposes. They include:
'A' Command - reports jumper settings of each individual module
'S' Command - reports overall system settings, including Power Supply voltages
Please contact the factory for assistance in any other updating or reprogramming needs.
DSP Modules
Each DSP module has signal processing for two audio channels. Overload and Normal
Level indicators are provided for each channel. A Heartbeat Status LED flashes at a
one-second interval to show proper operation. The input and output audio interface
are balanced 600 ohm lines with audio transformers. A watchdog timer monitors circuit
operation and will reset each the module in the event of program failure. To insure
that audio is never interrupted, each audio channel is passively relay bypassed when
the unit is unpowered.
