Reference Manual
High Limit:
Sets the upper bound above which the system will report a “high” error status.
Low Limit:
Sets the lower bound below which the system will report a “low” error status.
Nominal Load Impedance:
Sets the expected average impedance for the connected load.
This value determines the output signal level required for the test. This parameter is also
used by the average power limiter to determine the expected power threshold. (See Section
4.2.25).
Report Error to Network:
Enables Error Reporting to send an error report via the network
so that high and low load conditions are reported to the IQ software. (See Section 4.2.17).
Report Error to Aux:
Enables and high or low load error to be reported by the AUX output.
(See Sections 4.2.17 and 6.1.)
Test Indicator:
This indicator is active when the amplifier output signal is sufficient to
allow load impedance calculation and test verification.
Low/Normal/High Indicator:
This indicator shows the present status of the load imped-
ance with respect to the user-defined high and low limits.
Z Average Monitor:
Reports the actual calculated average load impedance in ohms. Its
range is from 0 ohms to 255 ohms.
4.3 CobraNet
CobraNet is a licensed technology developed by Peak Audio, Inc. consisting of proprietary
communications protocol, firmware and hardware. It allows reliable, deterministic transmis-
sion of digital audio over a 100Base-T Fast-Ethernet network. The IQ-PIP-USP3/CN oper-
ates as a networked device on a CobraNet network, and interfaces digital audio from the
network to the amplifer. Refer to Section 5.3 for a more thorough discussion about CobraNet
technology.*
This section describes the IQ-PIP-USP3/CN’s CobraNet control and monitoring features.
These features are accessed via IQ for Windows software. Please refer to the IQ for Windows
documentation if you are unfamiliar with IQ software.
4.3.1 CobraNet Module Parameters
The internal CobraNet Network Interface Module contains several parameters for control and
monitor of status of the CobraNet network, and do not directly affect the IQ network. These
variables can also be controlled and monitored through the CobraNet network using Cobra-
CAD™** or other industry-standard SNMP-enabled network management software.
*For the most comprehensive information available on CobraNet technology, visit Peak
Audio’s CobraNet website at www.peakaudio.com/CobraNet/.
**CobraCAD is a software tool that provides a simple graphic user interface for the design,
configuration and monitoring of CobraNet networks. It is available for download from Peak
Audio’s website at www.peakaudio.com/CobraNet/.
