1.0 Purpose of this Document
This document discusses how to setup, configure, and use the LAN-520X LAN1and NC-485
Network Converter to provide LAN/WAN Ethernet connectivity between a PXL-500/PXL-510
Master controller and one or more PXL Slave controllers.
This document discusses how to setup, configure, and use the LAN-520X with the NC-485X
Network Converter to provide LAN/WAN Ethernet connectivity between two or more PXL RS-485
network segments. The following topics are covered:
• Overview
• LAN-520X with NC-485X Network Converter Setup
• Using the LAN-520X with Multiple PXL Networks
• Basic Ethernet Troubleshooting
NOTE: The NC-485X is an updated version of Keri’s NC-485 device. If you are using the new NC-
485X with a LAN-520, you must use the updated LAN-520X module. The original NC-485
Network Converter is NOT compatible with the new LAN-520X.
2.0 Overview
The LAN-520X, when used in conjunction with a NC-485X, provides companies the ability to use
their existing LAN/WAN for RS-485 communication between a Master PXL and multiple Slave
PXLs. Since LAN/WAN networks can be global, using the LAN-520X with a NC-485X provides the
ability to have Slave PXLs located throughout the world managed from one central location.
NOTE: If all network segments are not located within the same time zone, the time zone where the
Doors software is located will be used. For example, a site has network segments located in both
the Mountain and Pacific time zones with the Doors software on a computer in the Pacific time
zone. If an Auto Unlock/Lock is set on a controller in the Mountain time zone for 9 am, the
controller will not auto unlock/lock until 9 am Pacific time (the location of the Doors software),
which would then be 10 am Mountain.
The LAN-520X supports two communication channels. Channel 1 is used for RS-232 communication
and Channel 2 is used for RS-485 communication. The RS-232 communication is identical to that of
a LAN-505. The LAN-520X replaces the LAN-505 for serial over Ethernet communication. In order
to provide RS-485 communication over Ethernet, the LAN-520X must be connected to the NC-485X
Network Converter.
The drawing below shows a conceptual PXL network. Each PXL network segment contains one
LAN-520X connected to a NC-485X. The network segment containing the master must have the
LAN-520X/NC-485X connected to the PXL Master. Only one LAN-520X/NC-485X combo can be
1. The LAN-520X may be used with a PXL-500/PXL-510 only.

installed on a network segment. A maximum of 48 network segments can be connected to a PXL
Master. It is also possible to connect a PXL network outside of the Local LAN by utilizing a VPN or
WAN.

2. The 2-conductor lead (J103) connects to the JP-9 connector located at the top right corner of the
PXL.
3. Pin 1 of J103 on the NC-485x connects to Pin 1 of JP-9 on the PXL (see Figure 3).
Figure 3: Installation of the LAN-520X with NC-485X Network Converter
3.2 LAN-520X
The LAN-520X plugs into J101 on the NC-485X1(see Figure 2 on page 2). The LAN-520X can be
configured in one of two modes: Master mode or Slave mode. The LAN-520X connected to the PXL
Master must be configured in Master mode. Only one LAN-520X Master can exist in a PXL network.
All other LAN-520X units within a PXL network must be configured in Slave mode.
This document assumes that Channel 1 of the LAN-520X Master has been configured with an IP
address. Refer to the LAN-520X LAN Port Installation Guide (P/N 01504-001) for basic setup and
configuration. Note the Channel 1 IP address of the LAN-520X Master. For each LAN-520X/NC-
485X Slave, assign the Remote IP address in the Channel 2 configuration as the LAN-520X Master
Channel 1 IP Address.
The default Channel 1 configuration settings for the LAN-520X should be sufficient for the LAN-
520X Master.
1. Later versions of the NC-485X have the LAN-520X plug into J102 on the NC-485X.

To use the LAN-520X in a WAN environment, the following rules must be met:
• Network Routers must be configured to connect the LAN subnets.
• Ports 9999, 10001, and 10002 must be allowed to pass through the router.
• The Gateway IP address must be configured for the LAN-520X Master and any LAN-520X slave
outside of the Master’s subnet. Use option 0 Server in the Telnet connection to configure the
Gateway.
• No more than 12 IP addresses can be entered into the LAN-520X Master Hostlist.
NOTE: Configuration of Routers must be handled by knowledgeable IT personnel.
3.2.1 Channel 2 Configuration Settings
3.2.1.1 Master Mode Configuration
There are a few critical parameters to set via Telnet, all other parameters should be left at their default

3.3 Using Multiple PXL Networks on the Same LAN Subnet
If two or more PXL Networks using RS-485 over Ethernet exist on the same local subnet, it is
recommended that each LAN-520X Master have a different Channel 2 port number.
For each PXL Network, change the Channel 2 Port setting on the LAN-520X Master and Slaves to a
unique number. It is recommended that the port number be incremented by one digit for each
network. The first network’s LAN-520X Master Channel 2 Port is set to 10002, next Port is 10003,
etc. Next, change each of the Channel 2 Remote IP Address for the LAN-520X Slaves to correspond
to their LAN-520X Master’s Port number (see Figure 7).

4.0 Ethernet Troubleshooting Guide
This section provides some basic troubleshooting information should you have trouble connecting to
a LAN-520X.
NOTE: This section assumes you have a working knowledge of computer networks. For the
troubleshooting process, you should consult with the system or network administrator.
4.1 Verify the LAN-520X Settings
1. Verify the Channel 1 settings as described in the LAN-520X Installation Guide (p/n 01504-001).
2. Verify the Channel 2 settings as described in “Channel 2 Configuration Settings” on page 4.
4.2 Verify the LAN-520X is Online
1. Ping the IP address of the LAN-520X. If the ping fails, that means a communication connection
cannot be made. Possible reasons are:
- There is no power to the LAN-520X unit.
- The IP address was not programmed properly.
- Another device on the network has that same IP address.
- The IP address is unreachable to that segment of the network.
Contact the system or network administrator to resolve these issues.
4.3 Troubleshooting the LAN-520X with the NC-485X
This troubleshooting section deals with possible problems using the LAN-520X with the NC-485X. If
the solutions offered here do not work, be sure to also consult the LAN-520X Installation Guide (p/n
01504-001) or the PXL-500/PXL-510 Quick Start Guide (P/N 01918-001).
