Issue What is the difference between the Model 1119T and the Card-View Plus (Card Access Control Data Entry)? Environment I/NET Site Cause What is the difference between the Model 1119T and the Card-View Plus (Card Access Control Data Entry)? Resolution The Model 1119T has been customized to easily work with TAC�s I/NET software (INET 2000 and INET Seven). The unit has five modes of operation for the different functions it can perform. The modes are explained further in the Description and Operation sections of the owner's manual. It has a recessed mode switch-button to toggle between the different modes, and the display constantly shows an abbreviation indicating the mode currently in use. It includes a plug-in wall transformer to provide power.

Issue What mode is the Model 1119T when it is powered up (Card Access Control Data Entry)? Environment I/NET site Cause What mode is the Model 1119T when it is powered up (Card Access Control Data Entry)? Resolution The unit always enters the mode it was in when shut off. INET is the default mode entered when the unit is powers up for the first time.

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.

Issue I/NET 2000 setup is quitting at 10% installed, and giving an error message to the effect; "An error occurred during the move data process", then it mentions the file name vequalapi.dll, why? Environment I/NET 2000 Site Cause I/NET 2000 setup is quitting at 10% installed, and giving an error message to the effect; "An error occurred during the move data process", then it mentions the file name vequalapi.dll, why? Resolution You are using an obsolete CD driver that cannot handle long file names.

Issue How can I get audible alarms with I/NET 2000? Environment I/NET 2000 site Cause How can I get audible alarms with I/NET 2000? Resolution First, in Control Panel, sounds, ensure that a sound is selected for default sound. That is the sound I/NET will use. Second, if you cannot hear anything, and you have the amt configuration set for either timed or constant, it does work with the small speaker inside your pc. The trouble is, it may be barely audible or your pc may not have a little speaker inside. If so, you may want to purchase a sound card and speakers.

Issue What are the cable requirements? What is the maximum wire length? When do I add a repeater? What is the maximum number of repeaters allowed? Product Line TAC INET Environment I/NET Controller LAN, C-LAN Cause Incorrectly run controller LAN wire can cause communication issues between I/NET controllers and hosts.

Issue Can NPR 2000s be installed on a network that implements VLSM and CIDR? Environment I/NET Site Cause Can NPR 2000s be installed on a network that implements VLSM and CIDR? Resolution If you see anything other than 0 or 255 in the subnet mask of a PC or NPR, this is usually an indication that the customer is using Variable Length Subnet Masking on his network nodes and Classless InterDomain Routing on his commercial routers. The subnet mask gets logically handed with the TCP\IP address in some way and the router passes through a different address than the host/NPR actually sends. This reduces the number of TCP\IP addresses that a domain must register but the NPR 2000 cannot do this. The customer has the choice of only using PCs to the exclusion of NPRs (and that is a maybe), abandoning the VLSM/CIDR approach, or enabling proxy-arp on his commercial router.

Issue Which ports must be open on a commercial router in order to communicate with an NPR over a WAN? Product Line TAC INET Environment I/NET NetPlus Routers (NPR) Model Series 2000 Cause In most cases when communication occurs over the Internet or Corporate Networks, firewalls are in place to block unwanted traffic. I/NET utilizes Ports 50069 (set by default). These ports usually need to be configured within routers to allow I/NET to communicate correctly. Resolution For successful communication for I/NET over TCP/IP all routers must have these ports open / non-filtered I/NET Ethernet communication is via UDP port 50069  Telnet on the standard telnet port 23. A suggestion for those difficult IT departments who have setting to block ports and communication, one more solution suggested that I/NET be moved off the house network and put on a subnet. If the IT gurus really know their stuff, they would understand that. I/NET is providing a valuable tool for their company, saving tons of money, and the have it on their house network! Creating a clean subnet is essentially a free solution, all that has to be done is configure the ports on the network, and let I/NET run clean and freely without all their firewall and control settings. There is no need to have it on the house network and then the Hosts could see and communicate with the routers without issue.
