1. Introduction

Atop SW2001 Wireless Serial Server is a gateway between Ethernet (TCP/IP) and RS-232/RS-485

communications. It allows almost any serial device to be connected to a new or existing wireless network.

The information transmitted by SW2001 is transparent to both host computers (IP network over wireless

LAN or Ethernet) and devices (RS-232/RS-485). Data coming from the wireless LAN or Ethernet (TCP/IP)

is sent to the designated RS-232/RS-485 port and data being received from RS-232/RS-485 port is sent

to the Wireless or Ethernet (TCP/IP) transparently.

In the computer integration manufacturing or industrial automation area, Atop SW2001 Wireless Serial

Server is used for field devices to direct connect to Ethernet network. Terminal Server (main control

program run in SW2001) transforms whatever data received from RS-232/RS-485 to TCP/UDP port then

connects devices to the IP network via a single application program or multiple application programs.

Many control devices provide the ability to communicate with hosts through RS-232/RS-485 however

RS-232/RS-485 serial communication has its limitations. For one, it is hard to transfer data through a long

distance. With Atop SW2001, it is possible to communicate with a remote device in the Intranet

environment or even in the Internet and thus, increases the communication distance dramatically.

Flexible configuration options enable this unit to be setup remotely over IP network by Telnet, web browser,

or Window utility. Packed in a rugged DIN Rail mountable case and 9~30V DC power input range,

SW2001 is ideal for almost any industrial and manufacturing automation.

3. Hardware Installation

§ Prepare necessary cables, hub, power cord and RS-232/RS-485 connector.

§ Place SW2001 to the area that an access point can cover, or connector it via Ethernet cable with RJ45

connecor.

§ Connect a serial device to a serial port of SW2001, make sure the right connection of either RS-232 or

RS-485.

§ Plug in DC-9-30V, the buzzer will beep and the RUN LED will blink if SW2001 functions normally.

Please refer to Appendix A.5 to see all of LED messages.

§ Use monitor.exe configuration utility in the product CD or diskette to diagnose SW2001. If it starts up

successfully, you are able to find the IP and MAC addresses of SW2001. You can change the network

parameters of SW2001 to join your LAN by changing its IP address, gateway IP address and subnet

mask.

Note: If there are more than one access points, the access point’s ESSID must be the same.

3.1 Configuration

Atop SW2001 Wireless Serial Server is shipped with default settings shown in the following table:

Property Default Value

IP Address 10.0.50.100

NOTE: Atop provides a default button to restore system settings including IP address, gateway IP address

and subnet mask etc. to the defaults. Press and hold the default button for 5 seconds till the server

reboots.

3.2 Assigning a new IP Address by ARP command

arp –s is used to assign a static IP address of SW2001 and add this static entries to the ARP cache of the

computer, when TCP/IP packet with destination port number 1 is sent to SW2001, it causes the device to

check its MAC address with IP address, once SW2001 finds those two unmatched, it will reboot and

change to the new IP address which was set by arp –s command. The following example uses ARP to

assign a static IP address of SW2001 using its MAC address printed on the label of the rear panel, then

User manual Version 1.0

ABLELink Wireless Serial Server

SW2001

10 / 51

use Telnet to send the TCP/IP packet with destination port number 1 to SW2001, after SW2001 reboots it

will change its IP address to the new one.

Note:

1. Arp command can only be used to set a static IP address of SW2001 using system reset user name

admin and default password null.

2. Only TCP/IP packet with destination port number 1 will lead SW2001 to reboot and change the IP

address.

3.3 Auto IP

A DHCP server automatically assigns the IP address and network settings. SW2001 supports DHCP.

It will supply for the unit with an IP address gateway address, and subnet mask. You may use

Monitor.exe software to search network information automatically by putting a check on Auto IP on

Dialog window.
