Issue What is a MIP? Environment I/NET site Cause What is a MIP board? Resolution The Memory Interface Processor (MIP) is a plug-in module that provides significant functional and speed enhancements to TAC products. It provides increased processor performance and enables 96 K of on-board RAM for I/NET-related processing. The MIP is installed by removing the process and other memory chip(s). (The MIP is not designed to be used with all or our products!) Refer to TCON101 and TCON123.

Issue Does a site need to define a Link in the Configuration Profile for Integrated Dial? Environment I/NET Site Cause Does a site need to define a Link in the Configuration Profile for Integrated Dial? Resolution Yes, a site does need to define a Link in the Configuration Profile for Integrated Dial? Refer to TCON 226.

Issue Dip Switch settings to set a 78010 Tap as a Host LAN Tap Environment I/NET site Cause Dip Switch settings to set a 78010 Tap as a Host LAN Tap Resolution Place switches 4 and 5 down. Refer to TCON 101.

Issue How do I set the address for the 78010 Tap? Environment I/NET site Cause How do I set the address for the 78010 Tap? Resolution Positions 1,2, and 3 of DIP switch SW1 define the TAP address. This address identifies the Tap when connecting through I/NET software. The Tap address can be set at 0 - 7 when direct connecting to a host LAN, and it will always be address 0 when connecting to a controller LAN. The switches are binary with their values being active when in the up position.

Issue How to set the address for the 78020 Tap? Environment I/NET site Cause How to set the address for the 78020 Tap? Resolution Dip switch positions 1,2,3, and 4 are used to set the Tap's Link address (0 - 15). The switches are binary with their values being active when in the up position.

Issue What cables are required for 7804 Taps? Environment I/NET site Cause What cables are required for 7804 Taps? Resolution Workstation to Tap Aux port - model number CBL004 Tap Telephone Port to Phone Line  - model number CBL013

Issue What is Integrated Dial? Environment I/NET site Cause What is Integrated Dial? Resolution Integrated Dial is another I/NET feature that enables communication from a single workstation to controller or host LANs through external asynchronous modems. Communication provided in this configuration is one-way to initiate all calls from the host workstation. No automatic dialing functions are provided for alarms or messaging

Issue What situations may require Auto Dial / Auto Answer (ADAA)? Environment I/NET site Cause What situations may require Auto Dial / Auto Answer (ADAA)? Resolution This application is used when point alarms, messages, transactions and other user-define conditions require immediate attention. This application is also used when automatic collection of data is required. Docutrend and Access Control reports are examples of data collection.

Issue What is a 7810 Tap? Environment I/NET Site Cause What is a 7810 Tap? Resolution The 7810 Tap is a special purpose Tap allowing a printer to connect directly to a controller LAN without using a workstation. This is also referred to as a Printer Tap.

Issue Tap not communicating with Host. (Refer to TCON 101 and TCON 226) Environment I/NET 7801 Tap Cause Multiple causes are possible.  Resolution Check connections at the host port Verify Switch settings Ensure you are using the correct cable Check the Tap version Check the Baud rate set in the set up Check the Comm Port defined in setup

Issue Tap does not auto dial out when an alarm occurs Environment I/NET 7801 Tap Cause The phone number(s) are not defined by the host software  The wrong message priority is defined The message masks do not match Resolution Verify Phone numbers Ensure Alarms are set to Priority or Critical Verify Message Masking

Issue Site plans to install more than 64 remote ADAA (asynchronous) sites to communicate to a Embedded 4X host. What are some of the tasks? Environment I/NET site Cause Site plans to install more than 64 remote ADAA (asynchronous) sites to communicate to a Embedded 4X host. What are some of the tasks? Resolution Plan! Consider which points are critical, then consider which sites are most critical (Do you really need every Message or Transaction to dial the Host immediately?) At the Host, build the Configuration Profile with the link addresses of the network Start I/NET. Set up your Network Configuration (If you are doing Docutrend, set this too!) Give each Remote Site a Unique Name and Site Number (use the INET Help Screens!) (Please, don't leave each site at link 0.) Set up each Site's Tap editor: When to Dial Who to Dial? What will cause a Dial? Link? (Remember, set it for what is needed and read the Help Screens) Save the Site Tap configuration Do frequent backups of your Host's files (This includes NETCON and SITEXXXX.SAVs)

Warning Potential for Data Loss: The steps detailed in the resolution of this article may result in a loss of critical data if not performed properly. Before beginning these steps, make sure all important data is backed up in the event of data loss. If you are unsure or unfamiliar with any complex steps detailed in this article, please contact Product Support Services for assistance. Issue How do I change the power line frequency setting on the 7716 / 7718 / 7756? Environment I/NET  Hand Held Console (HHC) Cause How do I change the power line frequency setting on the 7716, 7718, 7756? Resolution Physically remove the I/O points from the controller. See TCON 096 for details. Using the HHC, press [Code] , 92, [Enter] to select the AC line frequency Press [Inc] or [Dec] to switch between 50 an 60 hertz Press [Enter] to accept your choice After downloading the software and database, place the external points on the 7716 (or 7718 and 7756) Place the controller on the LAN Note:  Code 92 is not required for any of the 779x Interface's. Entering this code on the Hand Held Console will produce the error LED to illuminate. 

Issue What type of processor is in the 7716? Environment I/NET Site Cause What type of processor is in the 7716? Resolution The 7716 controller is based upon the 486 microprocessor.

Issue How many addressable points can the 7716 supervise or control? Environment I/NET site Cause How many addressable points can the 7716 supervise or control? Resolution The 7716 can supervise or control 200 points

Issue What is the usual Controller LAN speed? Environment I/NET Controller LAN Cause The baud rate for all controllers on the LAN must be set to the same. The default or typical LAN speed is usually sufficient for most installations. Resolution The controller LAN speed is usually 19200 baud.

Issue On the 7716, what is the baud rate of the Hand Held Console (HHC) P1? Environment I/NET site Cause On the 7716, what is the baud rate of the Hand Held Console (HHC) P1? Resolution The baud rate is 1200 on P1.

Issue Which of the IC chips on the 7716 holds firmware information? Environment I/NET site Cause Which of the IC chips on the 7716 holds firmware information? Resolution U4 holds the firmware information.
