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)

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 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.

Issue PE Programs cause Locks to go into "Inoperable Mode" Environment Continumm version 1.94 and above Cause Personlized PE Program causes the locks to go into an inoperable mode due to the constant polling of the PIM for lock status based on the program characteristics. Resolution To resolve this issue, please follow these steps: Do not use PE Programs to poll lock status it would minimize battery life Disable all PE Programs that are lock specific. Do not use PE Programs for Schlage Integration.

Issue Can a 7716 emulate a 78061 Tap? Product Line TAC INET Environment I/NET site Cause This emulated Tap requires the use of an optional RS232 expansion module. Using this Tap function, you can connect a Hayes compatible modem to port P2 of the RS232 expansion module. You may then configure the modem for auto-dial/auto-answer (AD/AA) operation. Resolution A 7716 can emulate a 78061 Tap. Using the Hand Held Console (HHC): Press [Code], 90, [Enter] The emulated device type model number displays in the read out Press [Inc] or [Dec] to toggle through 7801, 7803, or 7806 Tap emulation Press [enter] to accept your choice You will need the RS-232 expansion card for ADAA See TCON 096 for details.

Issue How to use an LTS80 (Lini-Temp) sensor on a 7716 as a two-circuit.  Product Line TAC INET Environment I/NET Site Cause How to use an LTS80 (Lini-Temp) sensor on a 7716 as a two-circuit.  Resolution Place a 10K ohm,1/8 watt resistor in the corresponding resistor "A" position. Jumper J22 to 15V For Fahrenheit, M = 0.21978, B = -459.6 For Celsius, M = 0.12210, B = -273.0 Using the first input on TB1 as an example, place the white lead of the sensor on terminal 1, place the orange on terminal 3 (+V)
