Issue What are 7806 Site Taps? Environment I/NET site Cause What are 7806 Site Taps? Resolution These series of Taps connect one or more controller LANs to a workstation through a companion 7804/78041, or to a host LAN through a 7805/78051 Tap using a Direct Distance Dial telephone network. (Refer to TCON 101, Model 7806 Site (LAN) Taps).

Issue What is a Repeater Tap? Environment I/NET Site Cause What is a Repeater Tap? Resolution This is a special purpose Tap with a single model in the series. The 7808 Repeater Tap extends a controller LAN's Segment distance, "T" connection distances, or extends the maximum number of devices allowed to connect on the controller LAN. Note: The 7808 Repeater Tap communicates only at 19200 baud. It will not work on a controller LAN that runs at 9600 baud. Refer to TCON 101, Model 7808 Repeater Tap

Issue What is a 7808 Tap? Environment I/NET site Cause What is a 7808 Tap? Resolution It is also known as a Repeater Tap. This is a special purpose Tap with a single model in the series. The 7808 Repeater Tap extends a controller LAN's Segment distance, "T" connection distances, or extends the maximum number of devices allowed to connect on the controller LAN. Note: The 7808 Repeater Tap communicates only at 19200 baud. It will not work on a controller LAN that runs at 9600 baud. Refer to TCON 101, Model 7808 Repeater Tap.

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.
