IP LAN Access Controller (LT-20IP): Connectivity and addressing instructions for integrating the LT-20IP controller into a LAN/WAN infrastructure, including MAC address settings and network configuration.

Overview: This document provides detailed instructions for setting up and configuring LT-20IP controllers within a LAN environment. It covers installation procedures, IP settings configuration, and network setup for access control systems.

Specifications: Each LT-20IP controller has a factory default IP of 192.168.127.254 and a Subnet Mask of 255.255.0.0. The TCP/IP settings of the LAN adapter at the local host PC should also have a Subnet Mask of 255.255.0.0.

Installation Procedures: To install the network enabler utility, run ‘Utility_Setup.exe’ from the Link CD. Use the ‘Configuration_Broadcast Search’ option to list all IP controllers on the network. If controllers are not found, check for IP addressing or LAN issues.

Changing Controller IP Settings: Unlock the controller using the MAC address, then modify settings under the Basic and Network tabs. Ensure the Server Name is descriptive and limited to 17 characters. Request a unique IP address from the LAN administrator for each controller.

Link.net Server Configuration: After setting unique IP addresses, configure the Link.net Server software. Use the TCP/IP Channel Tab to enter IP settings and a port number of 4001, unless advised otherwise by the network administrator.

Addressing Controllers: Each controller requires a unique electronic address (EID) set by a 6-way DIL switch. Dipswitches 1-5 establish the EID, while switch 6 sets the operating mode.

Network Setup: Choose the correct network interface (RS232, USB, or IP) and ensure proper addressing. Use CAT5 UTP or Belden 8723/9503 cable, and avoid exceeding 1200m of cable length. Screened cable is recommended for longer distances or industrial environments.

USB to RS232 Interface: If an RS232 port is unavailable, use a USB to RS232 interface to create a virtual serial port. Install the driver from the CD and note the COM port number for configuration.

RS232 Network Interface: Connect the network to a computer port or USB virtual serial port using the 485HF9 interface. Two connection methods are available: Controller Powered Network and Locally Powered Network.

Interconnecting Controllers: Avoid parallel cable runs with power facilities and use a mutual pair for TX and RX. Employ network line termination with a 120R resistor for cable lengths exceeding 200 meters.

Reader Interface Card Installation: For token administration, install a dedicated desktop take-on reader using an LT-RIB interface PCB.

Software Installation: Install the Link.net application software from the provided CD.

Installation Procedure:
To install the software, insert the CD into the PC's CD drive. If the installation does not start automatically, navigate to the root directory of the CD and run the setup.exe file. Follow the on-screen prompts to complete the installation.

Accessing the Software for the First Time:
The software includes a default user profile named 'Manager'. To access the software, select 'Start', 'Programs', and 'Link & Link.net Access Control'. Enter 'Manager' as the password (note the uppercase 'M') and select OK. This will launch the 'Plug & Play Controller Manager'.

Plug & Play Controller Installation:
Upon initial installation, the Plug & Play Manager activates automatically. Confirm the default port or select a different one if necessary. Ensure the 'Enable Link Networking' box is checked to establish networking. Connect the Link.net hardware to the PC. The software will detect individual controllers and list them. Close the System Network Controllers window once all hardware is detected.

Manual Controller Installation:
For additional controllers, use the 'Install New Hardware' function in the Tools menu. Select 'Controllers' from the Access Control menu and click 'Install New Controller'. A new controller record is created, assigning the first available free network address.

Changing Controller Parameters:
Set individual parameters for each controller by selecting the controller entry and opening it. Assign names for nodes, set unlock time, and configure interlock situations if applicable. Customize messages for General Purpose Inputs and apply changes.

Selecting the Global Access Control Interface Type:
The LT-20AC Access Controllers support both Wiegand and Clock & Data standards. To change the interface type, adjust settings in the View_Options_Reader Options section and send the information to the controllers. This setting is non-volatile.
