Resman Troubleshooting GuideResman Errors and WarningsDevice did not respond to MODID If you get a warning indicating that a device is not responding to Modid lines, this may be normal as some devices do not use the P2 connector which contains the Modid lines. In particular, many B-size VXI devices do not contain a P2 connector and VME devices do not have Modid lines.
Unable to initialize VXI driver These errors are indicative of the fact that the NI-VXI device driver is not installed properly, or that it is not loading properly, possibly due to a conflict with some other memory resident program or device driver. Make sure that you have installed the appropriate NI-VXI driver and disable any memory resident programs and non essential device drivers: This is accomplished by
adding the line "device = emm386.sys x=0xD000-0xEFFF" to your config.sys file and the line "emmexclude = 0xD000 - 0xEFFF" to the [386Enh] section of your system.ini file.
A VXI devices model code register specifies wether the device is capable of slot 0 operation. Slot 0 devices must have a model code value between 0 and 256. Therefore, this error maybe due to an error that occurred while reading a configuration register. You may be able to resolve this error by increasing the VXI/VME bus timeout setting on the VXI/VME bus controller. Note that the VXI/VME bus timeout should only be enabled on one device in the system - this should be a MXI device in systems that contain multiple bus mastering devices. You may see this error as a result of running Resman multiple times. The VXI specification does not technically allow you to run Resman more than once per chassis power cyle and some devices will not allow you to configure them once you have run the resource manager. This error may also be due to an error reading the devices word serial configuration registers. You may be able to resolve this error by increasing the VXI/VME bus timeout setting on the VXI/VME bus controller. Note that the VXI/VME bus timeout should only be enabled on one device in the system - this should be a MXI device in systems that contain multiple bus mastering devices.
Early revisions of the VXI specifications differed in the way that an instrument suppported Begin Normal Operation. Therefore, one possible reason for this error is that the device does not support the modern specification. This error may also be due to an error reading/writing the devices word serial configuration registers. You may be able to resolve this error by increasing the VXI/VME bus timeout setting on the VXI/VME bus controller. Note that the VXI/VME bus timeout should only be enabled on one device in the system - this should be a MXI device in systems that contain multiple bus mastering devices.
The Resource manager algorithm is responsible for dynamically allocating the A24 and A32 resources for all of the VXI
devices in a system and this error may be encountered when using VME devices and/or in multi chassis systems. Several factors need to
to be taken into consideration when implementing a multi chassis system as discussed in the
Configuring Multi Chassis Systems trouble shooting section.
The following rules should also be observed for all systems, particularly systems that use VME devices:
