1 What characteristics can bemodified?

1.1 Default CMC Device Type for Offline ModeDetermines the default device type for offline operation. When the Hardware

Configuration dialog is opened in offline mode, Test Universe providessimulation of all device types listed below. By setting this registry entry, thedefault device type can be specified, i.e., the device type set here will beselected by default.

Registry Settings

1.2 Ground Wire Break WarningSpecifies whether or not the ground wire break warning is displayed.

Note: The ground wire break warning is a crucial message! Disabling it willsuppress an important message that indicates a potential safety risk.

Therefore we suggest to disable this warning only if the ground wirebreak warning occurs constantly due to your network topology, and allCMC users are fully aware that this is the case!

Registry Settings

Key name: HKEY_CURRENT_USER\Software\OMICRON\HardwareConfiguration

Value name: DefaultDeviceTypeValue type: String (REG_SZ)

Value data: CMC56, CMC156-EP, CMC256-3, CMC256-6, CMC151

Key name: HKEY_CURRENT_USER\Software\OMICRON\HardwareConfiguration

Value name: GroundWireBreakWarning

Value type: String (REG_SZ)

Value data: 0 or 1

(0 = warning disabled, 1 = warning enabled. Default = 1)

Note: When "Value name" does not exist, the warning is

enabled.

1.3 Scanning of Parallel PortsDetermines whether or not CM Engine scans the corresponding parallel port forconnected CMCs. The default setting is "scan port".

Disabling a particular port from being scanned can be advantageous if ahardware device is connected to it that may conflict with the way the OMICRONkernel mode driver operates. Such a device can be a printer that, for example,every time the kernel mode driver switches, initiates an internal reset and ejects

a sheet of paper.Registry Settings

Key name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\OMICRON\ParCMC

Value name: ScanLPTx

(where "x" is to be replaced with the actual port number)

Value type: DWORD (REG_DWORD)Value data: 0 or 1 (default = 1)

0 = port is not checked for connected CMCs

1 = the port is included when scanning for devices

Note: When "Value name" does not exist, the port isincluded when scanning for devices.

1.4 Automatic Registration of the Kernel ModeDriversDetermines whether or not CM Engine automatically tries to register the kernelmode drivers for parallel port communication on each start-up. The defaultsetting is "register kernel mode drivers".

Note: This setting should only be used by very advanced users thatunderstand the impact of disabling kernel mode drivers.

Registry Settings

It may be advantageous to select not to automatically register the the kernelmode drivers if you experience a conflict with another driver. However, up todate, the only definitely known case is an incompatibility with the PPShell driverof the Windows CE development environment.

Setting the value data to 1 prevents CM Engine from automatically registeringthe kernel mode drivers, however, results in the fact that OMICRON TestUniverse can be operated in offline mode only.

1.5 Height of Analog Diagrams in Reports

Specifies the height in millimeters of analog diagrams in the test reports.Registry Settings

Key name: HKEY_CURRENT_USER\Software\OMICRON\CM Engine

Value name: RegisterAndStartKernelDrivers


Value data: 0 or 1 (default = 1)

0 = kernel mode drivers not automatically registered1 = kernel mode drivers registration attempted automatically

Note: when "Value name" does not exist, registration isattempted automatically.

Key name: HKEY_CURRENT_USER\Software\OMICRON\\Options

Value name: DiagramHeight


Value data: height in millimeters, value must be between 1 and 200

1.6 Software Watchdog TimeoutSpecifies the time-out for the software watchdog in the device.

Note: This setting should only be changed when advised by the OMICRONhotline.

Registry Settings

1.7 PC to Test Set Watchdog TimeoutSpecifies the time-out for the watchdog between the computer and theOMICRON test set (only relevant for CMC256 with NET-1 option).

Note: This setting should only be changed when advised by the OMICRONhotline.

Registry Settings


Value name: WatchdogTimeout


Value data: Watchdog timeout in milliseconds, value must be between 2000and 30000

Note: When "Value name" does not exist, the watchdogtimeout will be set to an internal default (currentlyabout 2000ms).


Value name: WatchdogTimeoutAL2DevEng


Value data: Watchdog timeout in milliseconds, value must be between 1000and 30000

Note: When "Value name" does not exist, the watchdogtimeout will be set to an internal default (currently3000ms).

1.8 Overload Disable TimeSpecifies a time span in which the overload detection is disabled after a signalchange.

Registry Settings


Value name: OverloadDisableTime


Value data: Overload disable time in milliseconds, value must be between15 and 25000, otherwise it is ignored.

Note: When "Value name" does not exist, the overloaddisable time will be set to an internal default (currently50ms).

1.9 Disable Hardware-Check Error MessagesThis setting disables one or more error messages of the hardware self-test.

Note: Edit with extreme caution! Working with a defective test set whoseerror messages are intentionally suppressed can be very dangerous!

Registry Settings


Value name: HWCheckDisableMask


Value data: The value is interpreted as 32 bit mask. Each bit in the maskdisables one error message:

1.10 Rogowski Simulation Amplitude Dynamics A new setting possibility for the dynamic amplitude range using the trueRogowski coil simulation of the CMC256 test set. Two dynamic amplitude rangemodes can be selected: "normal" (default) and "high".

"Normal" mode provides the security that the amplitudes do not exceed alimit which could result in distorted signals, even for higher frequencies, e.g.,400Hz. The amplitude, however, is limited to 5.9 times the nominal current

(assuming that 150mV voltage is the corresponding value for the nominalcurrent).

The "high" mode permits amplitudes of up to 37 times the nominal current (at150mV for nominal current). The price to pay for the higher dynamic range isthe danger of distorted signals if harmonics exceed certain limits (see thefollowing limits table).

Current limits for 50Hz nominal frequency and 150mV coming from theRogowski coil at nominal current in "normal" and "high" mode:

With this Service Release it is possible to do this setting directly in the WindowsRegistry (refer to the document "Test Universe Registry Settings.pdf" that is part

of this release). A more user-friendly solution will be presented in the next majorTest Universe release.

Normal Mode: High Mode:

f max. current f max. current

50Hz 5.9 x In 50Hz 37.0 x In

100Hz 5.9 x In 100Hz 23.6 x In

150Hz 5.9 x In 150Hz 15.7 x In

200Hz 5.9 x In 200Hz 11.8 x In

250Hz 5.9 x In 250Hz 9.4 x In

300Hz 5.9 x In 300Hz 7.9 x In

350Hz 5.9 x In 350Hz 6.7 x In

400Hz 5.9 x In 400Hz 5.9 x In

Registry Settings

Note: When "Value name" does not exist, the amplitude dynamics will be set

to "normal".

1.11 Separate Language Selection for Test ReportsBy default the language for user interface and test reports is identical (set on theStart Page at S Y S T E M S E T T I N G S | L A N G U A G E ).

This registry setting activates the possibility to select a report language differentfrom the user interface language.

Registry Settings

Note: This is not a 100% solution. For technical reasons, there are somestrings that will remain in the user interface language.


Value name: RogowskiAmplitudeDynamics


Value data: Either "normal" or "high"

Key name: HKEY_CURRENT_USER\Software\OMICRON\General Settings

Value name: AllowSeparateLanguageSelection


Value data: 0 disables a separate selection

1 enables a separate selection
