Issue Can I assign an IP address to each NPR after I place it on the network? Environment I/NET site Cause Can I assign an IP address to each NPR after I place it on the network? Resolution No. A unique IP address must be entered for each NPR before it is connected to the commercial network. (TCON209 2-27)

Issue What does the Subnet Mask field represent in the NPRs editor? Environment I/NET site Cause What does the Subnet Mask field represent in the NPRs editor? Resolution The Subnet Mask field indicates which sections of the IP address are used to indicate the network on which the NPR resides. (TCON209, 2-27)

Issue What may happen if the same IP address is used by more than one NPR? Environment I/NET site Cause What may happen if the same IP address is used by more than one NPR? Resolution A duplicate IP address will cause a system error message in I/NET, and the NPR will not initiate the appropriate LED error code. (TCON 209, 2-27)

Issue Can the NPR's configuration be protected with a Password? Environment I/NET site Cause Can the NPR's configuration be protected with a Password? Resolution Yes. The NPR configuration may be protected with a password to prevent unauthorized changes. (TCON 209, 2-30)

Issue Does the NPR have a Diagnostic Utility? Environment I/NET site Cause Does the NPR have a Diagnostic Utility? Resolution Yes. The NPR is equipped with a self-diagnostic function that runs every time the unit is powered up. Four LEDs on the upper right side of the unit provide feedback of the progress of this test, and indicate any error conditions. See TCON209, 2-31 and TCON184 NPR Installation Guide.

Issue What is a 78010 Tap? Environment I/NET site Cause What is a 78010 Tap? Resolution The Model 78010 Tap directly connects a workstation to a host LAN. I can also connect a workstation to a controller LAN. This Tap can also be used in conjunction with an external modem for dial-in applications. (Refer to TCON 101).

Issue What is a 7801R Relay Tap? Environment I/NET site Cause What is a 7801R Relay Tap? Resolution This Tap functions identically to the 78010 Host Tap. It differs in that it has two Normally Open (N.O.) relay contact outputs for alarms. Therefore, set the Tap's address and baud rates as you would for the 78010. (TCON 101)

Issue What is a Link Tap? Environment I/NET site Cause What is a Link Tap? Resolution This type of Tap can connect host LANs to a single controller LAN, as well as multiple controller LANs. (Refer to TCON 101, Model 7802 Link Taps)

Issue What is a 7802 Tap? Environment I/NET Site Cause What is a 7802 Tap? Resolution This type of Tap can connect host LANs to a single controller LAN, as well as multiple controller LANs. (Refer to TCON 101, Model 7802 Link Taps)

Issue What is a Site Tap? Environment I/NET site Cause What is a Site Tap? Resolution This Tap is also referred to as a 7803 Tap. This type of Tap connects controller LANs to Link Taps. (Refer to TCON 101, Model 7803 Site (LAN) Taps)

Issue What is a 7803 Tap? Environment I/NET site Cause What is a 7803 Tap? Resolution This Tap is also referred to as a Site Tap. This type of Tap connects controller LANs to Link Taps. (Refer to TCON 101, Model 7803 Site (LAN) Taps)

Issue What are 7804 Host Taps? Environment I/NET site Cause What are 7804 Host Taps? Resolution This series of Taps connect a workstation to controller LAN Taps (Site Taps) through a Direct Distance Dial (DDD) telephone network. They communicate to a companion model in the 7806 Taps, which forms the connection from a workstation to the remote controller LAN. (Refer to TCON 101 Model 7804 Host Taps.)

Issue What are 7805 Link Taps? Environment I/NET site Cause What are 7805 Link Taps? Resolution This series of Taps connect a workstation to controller LAN Taps (Site Taps) through a Direct Distance Dial (DDD) telephone network. They communicate to a companion model in the 7806 Taps, which forms the connection from a workstation to the remote controller LAN. (Refer to TCON 101, Model 7805 Link Taps.)

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.

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.
