Note: The LAN-520 AESP is an updated version of Keri’s LAN-520X device. If you are using the new NC-485X Network Converter with the LAN-520, you must use the LAN-520 AESP module (or the existing LAN-520X module). The original NC-485 Network Converter is NOT compatible with the new LAN-520 AESP (or the existing LAN-520X module).

Note: To set up the LAN-520, you MUST have technical knowledge of general networking in a PC environment. Please have a network administrator on site to resolve any special networking issues that might occur during device programming. Network topologies and strategies will vary.

1. Power down the PXL-500 Primary controller (controller addressed as #1).
   
2. On the Primary controller remove jumpers from JP6 and JP7.
   
3. Insert the LAN-520 AESP into the TB13 port of the PXL-500. Orient the unit as shown in figure 2.
   
   Note: Mounting screws are supplied to secure the LAN-520 AESP to the PXL. The PXL will have to be removed from its enclosure to do this.
   
   
   Figure 2 - LAN-520 Anchoring to PXL PCB
   
   
4. Connect the RJ-45 port on the LAN-520 AESP to the network via a patch cable, or directly to the PC using a cross-over cable.
   
5. The LAN-520 should be displaying 2 x green LEDs and 1 x yellow LED.
   
              
   
   
6. Power-up the PXL-500 (if this is a new PXL controller or it was from a Doors32 system and will now be used with Doors.NET, a ram reset is required).
   
   
   

3.0 Installing the LAN-520 to an EntraGuard Controller

Support for the LAN unit on Entraguard begins with PCB 23217-001 Rev. E. Earlier units cannot support a LAN unit.

3. Insert the LAN-520X into J7 on the Entraguard. Orient the LAN unit as shown in Figure 2.

Note: Mounting screws are supplied to secure the LAN-520 to the Entraguard unit. The Entraguard PCB will have to be removed from its enclosure to do this.

3. Enter a new static IP address or leave as is (if you are happy with the address that was assigned by DHCP). On this page you can optionally add a gateway IP address as well. A gateway address is not required if the PC running Doors32/Doors.NET is on the same subnet. Click Next again.
   
4. Click the Assign button to complete the static IP address assignment.
   
5. Click Finish when you see assignment has successfully completed. 
   

8.0 Setting a Static IP Address Using Telnet

Two basic commands are used in this method: ARP and Telnet.

Note: Address Resolution Protocol (ARP) is the standard method for finding a host's hardware address when only its network layer address is known. For more info on the usage of arp type ARP/? at the command prompt and press ENTER.

Information to be typed is displayed in bold.

1. Open a command prompt:
- (Enter CMD in the Windows search field).
- Press Enter.
- This will open up a Command Prompt (DOS) window.

2. At the prompt, type the following to make a Telnet connection to the LAN-520 AESP1:

arp -s <LAN-520 IP address><LAN-520 MAC address><ENTER>

    Example: C:\>arp -s 174.120.9.115 00-20-4A-24-89-67 arp –a

arp-a <ENTER>

telnet >LAN-520 IP address> 1 <ENTER>

Example: C:\>telnet 174.120.9.115 1

Note: A Telnet “Connection Failed” screen appears. This is normal.

Example: C:\>telnet 192.168.100.250 9999 <ENTER><ENTER>

(The Enter button must be pressed twice within 5 seconds).     

Note: The ARP command does not report when this command is completed successfully. However, if it has been done incorrectly, an error will occur. To verify the contents of the ARP table type arp -a and press ENTER. The MAC address should be paired with the IP address to be assigned.

The following menu appears:

Change Setup:

0 Server

1 Channel 1

2 Channel 2

5 Expert

6 Security

7 Defaults

8 Exit without save

9 Save and exit

Your choice?

Select option #7:

7 Defaults

This will set communications settings to the defaults which are the recommended channel 1 settings.

Note: This will not reset the IP or subnet settings in the unit.

0 Server

IP Address: Enter the IP address in segments then press enter.     

This will replace the numbers in parenthesis     

Example: 192.168.100.103 would be entered as:

192<ENTER>

168 <ENTER>100<ENTER>103

Set Gateway: Gateway will only be needed if you intend to communicate with another subnet.

Enter “Y” then enter address if needed as done with IP ADDRESS in the prior step, otherwise type “N” and proceed to next step.

NetMask: Number of Bits for Host Part: This number is a calculation of the subnet mask.     Most common are: 255.255.255.0 = 8 & 255.255.0.0 = 16

Note: See Section 7.0 for a description of how to calculate the number of bits.

9 - (Press 9 to save and exit).

9.0 Enabling Telnet Client on Windows 10

If you try to make a telnet connection to the LAN-520 but you see the following message: ‘telnet is not recognized as an internal or external command, operable program or batch file’ then it is likely that Telnet is disabled on the operating system.

Perform the following steps to enable Telnet in Windows 10:

1. From the Windows start menu go to Control Panel >> Programs and Features.
   
2. On the left of the program list click Turn Windows Features on or off.
   
3. From the Windows features list locate Telnet Client.
   
4. Place a check-mark against Telnet Client.
   
   
   Figure 9: Select to Enable Telnet Client

10.0 Set a Telnet/Web Manager Password on the LAN-520

Keri systems strongly recommends setting the LAN-520 with a password (to prevent unauthorized connections to the module).

Note: The following steps require Telnet to be enabled on the host PC.

1. Double-click the LAN-520 device listed in Lantronix Device Installer.
   
2. Select the Telnet tab and then click on the CONNECT button.
   
3. As soon as the Telnet sign-on screen appears, press <Enter> to go into the LAN-520X Setup mode. There is a two to three second window in which you must press <Enter> before the Telnet session automatically closes. If the Telnet session closes before you enter Setup mode (if nothing happens when you press <Enter>), simply click the button to establish the connection.
   
4. Once Telnet connects with the LAN-520 all current configuration information is displayed and the cursor is placed at the “Your choice” field.
   
5. Enter 0 to go into the device's server settings.
   
6. Enter through the list of options until you see: 'Change Telnet/Web Manager Password'.
   
   
   Figure 10: Option to set a password on the LAN-520
   
   
7. Enter Y for Yes, then enter.
   
8. Input the password you wish to assign to the device.
   

Note: If you forget or lose the LAN-520 assigned password you will need to perform a factory reset on the device (see section 2.0).

11. Additional Security Settings

You can change security settings via Telnet or serial connections only, not on the Web-Manager.

1. Perform a Telnet connection to the LAN-520.
   
2. From the device main menu screen, enter the number 6 to access the device security settings.
   

Figure 11: LAN-520 Optional Security Settings

Note: We recommend that you set security over the dedicated network or over the serial setup. If you set parameters over the network (Telnet 9999), someone else could capture these settings.

Caution: Disabling both Telnet Setup and Port 77FE prevents users from accessing the setup menu from the network.

Disable SNMP This setting allows you to disable the SNMP protocol on the unit for security reasons.

SNMP Community Name This setting allows you to change the SNMP community name. Community name is a required field for NMS to read or write to a device. The default setting is public. The name is a string of 1 to 13 characters.

Disable Telnet Setup Note: If you choose to disable this option, please note that disabling both Telnet Setup and Port 77FE prevents users from accessing the setup menu from the network. This setting defaults to the N (No) option. The Y (Yes) option disables access to Setup Mode by Telnet (port 9999). It only allows access locally via the web pages and the serial port of the unit.

Disable TFTP Firmware Upgrade This setting defaults to the N (No) option. The Y (Yes) option disables the use of TFTP to perform network firmware upgrades. With this option, you can download firmware upgrades over the serial port using Device Installer’s Recover Firmware procedure. (See Serial Port Recovery Procedure on page 5-3.)

Disable Port 77FE (Hex)

Note: If you choose to disable this option, please note that disabling both Telnet Setup and Port 77FE prevents users from accessing the setup menu from the network.

Port 77FE is a setting that allows DeviceInstaller, Web-Manager, and custom programs to configure the unit remotely. You may wish to disable this capability for security purposes. The default setting is the N (No) option, which enables remote configuration. You can configure the unit by using DeviceInstaller, web pages, Telnet, or serial configuration. The Y (Yes) option disables remote configuration and web sites. Note: The Yes option disables many of the GUI tools for configuring the unit, including the embedded Web-Manager tool.

11.0 Verify Communication By Performing a Telnet Session to Port 10001

This will test the default port used by Doors32/Doors.NET to communicate to the device.

The telnet command is preferred over the ping command in testing communications because the telnet command will give a specific response from the device, whereas the ping command may give a response from a different device (if there is a duplicate IP address on the network).

1. In a command prompt window type in, telnet [IP address] 10001 then enter.
   
2. If successful a blank screen and a blinking cursor will appear. The link LED (bottom green LED) will blink on and off on the LAN-520 AESP indicating that port 10001 is open. Close the command prompt window and the link LED should stop blinking.
   
3. If telnet is unable to connect, then review the settings. If the settings are correct then contact a network administrator to verify the needed ports are available. Some operating systems and hardware, such as routers and firewalls are set to block ports. Ensure these firewalls have ports 10001, 10021, and 9999, open for communication with the Doors32 or Doors.NET software.
   
   
   
   

   Note: If you are able to telnet into port 9999 in the command prompt but not to 10001, it is very likely that the ports required by Doors are blocked and will require that a Network Administrator address the issue so a successful telnet session to port 10001 may take place.
   

12.0 Enter the LAN-520 IP Settings into Doors.NET

This section explains the steps required to add a new PXL-500 to the system and then assign the LAN-520 AESP IP address to the controller. It assumes you already have the PXL gateway setup ready to add the new PXL controller(s).

1. Log into Doors.NET. 
   
2. Go to Setup >> Hardware Setup >> All.
   
3. Click the PXL gateway and then click on the Add PXL icon.
   
   
   
   
4. Enter a description for the new controller.
   
5. Select the specific model from the drop-down list.
   
6. Click Accept and the new PXL master controller will appear in the hardware tree.
   
7. Next, select Communication Channels.
   
8. From the ribbon bar select to add a 'Network' communication channel.
   
9. Select the new channel from the hardware tree.
   
10. Enable the channel via its properties on the right (set it from False to True).
    
11. Enter a new description for the channel, then save.
    
12. Select the new PXL from the hardware tree.
    
13. Assign the new communication channel via its properties on the right.
    
14. Once you have selected the network communication channel you will be able to enter the IP address (the IP address which has been set to the LAN-520 AESP).
    
    
    
    
15. Save your controller settings and within a few seconds the new controller should come online. You will see online events displayed in the live events grid.
