Purpose of this Document
This document discusses how to setup, configure, and use the LAN-520X LAN
1
and 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.

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.
