Issue What are some of the reasons why subnetting is used? Environment I/NET IP network Cause When considering network design, there are some reasons to consider subnetting. Resolution Overcoming distance limitations Interconnect dissimilar physical networks Filter traffic between networks

Issue What command displays the translation of the IP addresses to Ethernet addresses? Environment I/NET Cause This stands for Address Resolution Protocol (ARP). This command displays the table of translations between IP addresses and Ethernet Addresses. This table is built dynamically. When ARP receives a request to translate an IP address, it checks for the address in the (ARP) table. Resolution arp -a

Issue What situations may use Static Routing? Environment I/NET Cause A network with a limited number of gateways to other TCP/IP networks may be configured with static routing. Static routing tables do not adjust to network changes, so they should be used only where routes do not change. But when remote destinations can only be reached through one route, a static route is the best choice. Resolution A static routing table is constructed manually by the system administrator using the "route" command.

Issue If I have populated a Special Days and Temporary Time Schedule on a point, which schedule will control that point? Environment I/NET Time Schedule extension Cause There may be an overlap in scheduling that causes a Special day to fall on the same day as a Temporary Time Schedule. Resolution In the case of a point having a Special day defined and a Temporary schedule defined, the Temporary Time Schedule will override the Special Days schedule.

Issue Possible Issues related to a large number of global and indirect points Environment I/NET CLAN network Cause Adding a large number of global and indirect points can adversely affect the system response time. Resolution Each globalization and request for globalization is a message from the DCU. A large number of global and indirect points an overload the DCU’s message capability. This can reduce the system performance, and may cause the system to discard messages.

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.

Issue Calculations may not be used on an indirect point Environment I/NET Seven Resident I/O calculation Cause Calculations may not be used on an indirect point Resolution Calculations may be used only with internals or external points. Indirect points may not use the calculation extension.

Issue Can I use the 08 & 09 DI\DA points on a 7910A and 7920 DPU as internal points? Environment 7910A DPU 7920 DPU Cause These points are dedicated points and cannot be used for any other purpose. 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.

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.
