Issue Can ISDN be used to communicate to I/NET? Environment I/NET Site Cause Can ISDN be used to communicate to I/NET? Resolution I/NET is not designed to be compatible with the typical adapter of ISDN. ISDN, which stands for Integrated Services Digital Network, is a digital phone service that was popular a few years ago as an alternative to dial-up connections. ISDN allows data to be sent about twice as fast as a conventional phone line - up to 128Kbps (kilobits per second) rather than 56Kbps. As an added plus, a single ISDN line can be split into two separate channels, so you can carry on a voice conversation while your computer is connected to the Internet. It sounds great, but the catch is that it’s expensive. An ISDN connection doesn’t require a modem. Instead, you use a special ISDN Adapter, which may cost hundreds of dollars. In addition, you have to pay the Phone Company to install the ISDN line, and you pay a monthly fee for the line. On top of that, you may be billed by the minute for usage. With the spread of low-cost cable modem access in many areas and the cost of DSL access coming down, ISDN is fast becoming a thing of the past It was a good idea for its time, but its time has passed.

Environment I/NET Site Cause I need to convert the hexadecimal value of a key/card for an older I/NET system. Is there a TCON or any documentation on how to do this? Resolution Refer to TCON 237. Most calculators can convert decimal and hexadecimal. Windows also has this feature in the on-screen calculator.

Issue DPUs stopped letting people through doors after upgrading the site from I/NET 2000 to the latest revision of I/NET Seven Environment I/NET site with Access Control Cause DPUs stopped letting people through doors after upgrading the site from I/NET 2000 to the latest revision of I/NET Seven Resolution Using Dbcreate, select “Verify existing database” and start the process. You will probably find errors or differences listed at the end of the verification check. (This probably caused the crash.) Using Dbcreate, select “Upgrade database” and start the process. Force I/NET Seven to upgrade the system. (The upgrade will attempt to repair the differences.) Once again, “Verify existing database” the database using Dbcreate. There should be “0” (zero) differences. If there are no differences, then the database is ready to be used in I/NET Seven.

Issue Can an I/NET system communicate across ethernet routers which use Network Address Translation (NATing)? Environment I/NET Site Cause Can an I/NET system communicate across ethernet routers which use Network Address Translation (NATing)? Resolution In general, I/NET works best if we are able to pass an unadulterated packet of information from one host/NPR on the ethernet to another...and back again. Network Address Translation in a commercial router does just that; translates the address of a packet coming into the router to one of several devices that reside on the other side of it. I/NET workstations can successfully deal with NATing or spoofing because they utilize commercially available network drivers which do the communication for us. Under most circumstances, the NPRs can NOT because they have a limited set of network drivers which does not accommodate NAT....or DHCP for that matter. There are generally four different implementations of NAT. Static, Dynamic, Overloaded and Overlapped. The NPR will only stand a chance at working in a Static NAT implementation, but we do not recommend it. If you must install NPRs on such a network, call Product Support for assistance.

Issue What is Tuning? (History, DDC, PID, FLT) Environment I/NET Site Cause When speaking of History, DDC, PID, and FLT, what is Tuning?  Resolution Tuning is the on-line, automatic adjustment of PID or Floating module parameters. For more information refer to your System Operator Guide or TCON 083.

Issue Site has installed and "Tuned" a few PIDs and Float (FLT) modules in the controller but is not able to tune the last module added. What may be wrong? (History – Tuning) Environment I/NET Site Cause Due to the memory required for the tuning function, there is a limit of four modules that can be contained in the history record of each controller. Resolution If an additional module is needed, an old one must be deleted first. For more information refer to the System Operator Guide or TCON 083.
