Issue A Docutrend setup has Docutrend cells that will not update. Environment Docutrend Cause Points storing information to docutrend cells (including Event cells) must have at least a priority of routine when attached to a direct connect host, or the cell will not receive the data. On a dial out Tap system, points storing information on Docutrend cells (including Event cells) must have at least a priority, or the tap will not send the data. Resolution Check the system settings to ensure that points storing information to Docutrend cells have a priority of at least routine.

Issue Which controllers do not use the minimum trip and close command? Environment UC, MR, or ASC Cause The editor lets you enter a value in the minimum trip and close field; however, the UCI, MRI, MCI, or I/Site Lan replaces the entered value with the default value of "0" when it is downloaded to the UC, MR, or ASC. Resolution The minimum trip and close parameters are not used for Unitary Controllers (UC), Micro Regulator (MR), or Application Specific Controllers (ASC) output commands.

Resolution The 08 & 09 DI\DA points on a 7910A and 7920 DPU: Cannot be used as internal points Cannot have calculation extensions

Issue File equalization quit working. Troubleshooting steps to repair file equalization. Environment I/NET 2000 Cause Brdpend is a file equalization buffer, and should always be at 0KB.  Resolution Go to Windows Explorer Look in the Inet2000\data directory In this directory, look for a file called Brdpend. If this file is larger than 0KB, then delete this file. I/NET will make a new Brdpend file to replace the deleted one.

Issue Cannot get a DPU restore to work. Environment I/NET 2000 DPU Cause Acsave.tmc is a file that buffers the DPU restore information. It should disappear after a restore. Having the file present could mean that there was a problem with the download. Resolution Go to Windows Explorer Look in the Inet2000\data directory In this directory, look for a file called Acsave.tmc. If this file is present, delete it.   After deleting the Acsave.tmc file, do another DPU restore.

Issue A door DO is defined in the Resident I/O editor, but does not show up in the doors editor. Environment I/NET Resident I/O editor I/NET Doors Editor Cause  One of the causes is the doors are not saved in the NETCON file. Resolution Select Edit>Host Computer>Network Configuration Save any links with a "+" sign Select the link that contains the door and click Penetrate Save any controllers with "+" sign Select the controller that contains the door and click Penetrate Save any sub-Lan controllers with "+" sign Select the sub-Lan controller that contains the door and click Penetrate The door should have a "+" sign next to it.  Click Save All Close out of the Network Configuration Windows The door should now show up in the door editor.

Issue Is an existing IMI video frame grabber supported by Datacard? Environment Video Badging conversion from IMI to Datacard Cause IMI and Datacard are two different platforms with a defined upgrade path between them. Resolution The Flashpoint and Flashpoint lite, as most of the TWAIN devices are supported by the Datacard system. However, if the grabber card you have is not supported, a new card can be purchased from Datacard.

Issue Is a Magicard Video Badging printer supported by the Datacard system? Environment Video badging upgrade from IMI to Datacard Cause Depending on the existing printer, and upgrade from IMI to Datacard may require some steps to become operational. Resolution The magicard printer, used by the IMI System, can be used with the Datacard system. However, you will have to download a new printer driver from their Web Site (http://www.ultramagicard.com). If you have another type of printer, this printer may also have drivers on their web site as well.

Issue Will CSI/TAC formatted mag-stripe encoded cards be encoded during the Badge printing process using a datacard printer? Environment IDWorks Datacard printer Cause Event Handler ensures that the correct issue level is encoded on the card. Note: there are two version of the Event Handler. Resolution Yes you can, provided you add a plug-in called the "Event Handler" written by Datacard. 

Issue Does I/NET run on Windows 2000? Environment I/NET rev 2.20 Windows 2000 Cause At the time of release of Windows 2000, there was concerns about compatibility with existing I/NET installations. Resolution There has been a modification in I/NET revision 2.20 for it to operate with Windows 2000 normally.

Issue What is the Maximum character length that ID Works software supports? Environment IDWorks video badging system Cause Limitations of the text input fields. Resolution The Maximum character length for the Last name, First name and Field names 1-16 is 50 characters. Any longer names will be truncated.

Issue My NPR is flashing the LEDs from left to right, and I cannot get into the configuration editor. Environment NPR Cause It means the NPR is ready for a software restore. Resolution Once you load a bin file, you will be able to configure it.

Issue B-tree and rebuild can not fix a problem in an access control file Environment I/NET Access Control Cause You must first use the AC file conversion utility to convert it to a MDB format. Resolution Select mdb as the target file type Open the file in Microsoft Access Delete the problem records Run the AC file conversion to reconvert it back to AC file type Run the conversion from 1.XX to 2.XX.

Issue How to make local CPH work on a stand-alone MR-VAV-AX. Environment MR-VAV-AX Cause Even after you select local-CPH in the parameters and connect a contact to the local cph point, the unit probably won't switch modes without further modification. The application is looking for a zero for one mode and something above 1 for the other. Problem is that the factory calibration of the inputs can only be done to within 1 or 2 counts. With the standard conversion coefficient of 5 and 0, you'll still see a value of 5 or 10 for a shorted input. Changing the conversion coefficient wouldn't help because you need an absolute zero. Resolution Even though this is for stand-alone use, you need to connect the unit to an MCI or ISITE Lan. You can leave the address at 0 and set address 0 to MR or ASC in the MCU configuration. Open the ASC editors and update MCI for address 0 and check the point value for local cph with that input shorted. If it doesn't read 0, proceed. Next select Edit, Controller, MR functions. Highlight 0 and hit the Hardware button. These M and Bs are here as a result of the factory calibration. Reduce the B on input 02 (3rd entry down) by one or 2 or even 3 so that the local cph input reads 0 when shorted. When your done with the first one, you can plug in the rest and use the same MCI database provided you leave them all at 0.

Issue Why do the just created lighting circuits not appear in the zones sometimes? Environment I/NET Lighting controller Cause This is a known issue. This has been fixed in later revisions of I/NET. Resolution As a work around, Exit out of the Resident I/O or Summary screen Launching either screen again. Or you can go into the Edit > Controller > Zone Definition and attach the circuits to the zones there.

Issue What are the point address to be used as lighting circuits? Environment I/NET Lighting controller Cause Only certain points can be used to control lighting circuits. These are reserved. Resolution Use points 0-7 with a bit offset of 0-7. You may also use 8-11 for indirect circuits.

Issue What are the point address to be used as lighting zones? Environment I/NET Lighting controller Cause Only certain points can be used to control lighting zones. These are reserved. Resolution Use points 12 to 15 with a bit offset of 0-7

Issue When controlling a circuit point in the summary, the relay does not fire. Environment 7780 Lighting Controller Cause  PICO Fuse on the 7780 controller may be burned out.
