1. Introduction

1.1. Overview

PC-W Wireless Client Adaptor is a bridge between RS-232, RS422, RS-485, Ethernet based devices and
wireless LAN. It allows almost any Ethernet and serial devices to be connected to a new or existing wireless
network. The information transmitted by Wireless Client Adaptor is transparent to both host computers (IP
network over wireless LAN) and devices (Ethernet/RS-232/RS-422/ RS-485). Data from the wireless LAN is
transmitted to the designated Ethernet/ RS-232/ RS-422/ RS-485 port and data from Ethernet/ RS-232/
RS-422/ RS-485 port is transmitted to the Wireless (TCP/IP) transparently.

In the computer integration manufacturing or industrial automation area, Wireless Client Adaptor is used for
field devices to direct connect to network.

Many control devices provide the ability to communicate with hosts through Ethernet/RS-232/RS-485
however RS-232/RS-485 serial communication has its limitations. For instance, it is hard to transfer data
through Wireless or long distance. With PC-W, it is possible to communicate with a remote device in the
Intranet environment and thus, increases the communication distance dramatically.

Flexible configuration options enable this unit to be setup remotely over IP network by Web browser, or
Window utility. Packed in a rugged DIN Rail mountable case and 9~48V DC power input range, PC-W is
ideal for almost any industrial and manufacturing automation.

3.2. IP Assignment

3.2.1. Configure IP by Serial Manager Utility

Use Serial Manager, configuration utility that comes with Product CD-ROM to configure the network
parameters. For more details, please refer to Appendix B1.

Find a new device and IP assignment

 Use Serial Manager Utility to find the new device IP address or to get the device’s current IP

address as shown in Fig. 2.

 If needed, use Serial Manager Utility to re-assign a new IP address, Network Mask and Gateway

address to the new device.

 Users can also configure User ID, Password and Host Name using Serial Manager Utility.

Fig. 2. IP Settings using Serial Manager Utility software

Note: All settings will NOT be changed if User ID or Password was incorrect.

If there is more than one device using the same IP address in the same subnet, users need to correct the
mapping between MAC address and IP address using ARP commands as explained in the next section.

3.2.2. Configure IP address using ARP commands

ARP (Address Resolution Protocol) commands can be used to assign a static IP address on PC-W using its
hardware MAC (Media Access Control) address. The MAC address "0060E9-xxxxxx" is printed on the rear
side of PC-W. The following procedure show how to use ARP commands on MS-DOS Command Prompt
Window

Example: Set the IP address 10.0.50.101 to the MAC address 00-60-E9-00-79-F8

C:\> arp –s 10.0.50.101 00-60-E9-00-79-F8

arp –a command shows the current mapping IP and MAC addresses

arp –s “IP address” “MAC address” maps the IP address to a specific MAC address

Note: ARP commands can only be used to set a static IP address of PC-W

10

Fig. 3. Mapping IP address to MAC address using ARP Command

3.2.3. Configure IP Using Web Interface

Use common web browsers, e.g. Microsoft Internet Explorer or Mozilla Firefox, to configure the network
parameters of PC-W.

 Open a Web browser, type in the IP address (default IP: 10.0.50.100) of the PC-W to be

configured. The default user name is admin and the default password is null (leave it blank).

 From the Web Network links page, please configure IP address, subnet mask, and gateway

address, and then click “Save Configuration” to save all settings.

 Click Restart button to reboot the device to make the changes effective.

Please refer to contents of Web Configuration section for more details of the settings.

3.2.4. Automatic IP address assignment using DHCP

DHCP server can automatically supply an IP address, gateway address, and subnet mask to PC-W device
if its DHCP client function is enabled. By default, the DHCP client function is disabled, users can activate
the DHCP function by following these steps

 Execute Serial Manager Utility

 Click on the IP address of PC-W (This can be the default IP address if it was never set before).

 Click Config to pop-up the static IP Dialog Window.

 Check on Auto IP

 Click Config Now. (The PC-W will restart and obtain an IP from DHCP server automatically)

Note: You need to have a DHCP Server running in your subnet to automatically supply an IP
address. Please consult your network administrator if you are not sure.

3.3. TCP/IP Port Number

Default TCP Port numbers of PC-W are 4660 (1st port) and 4661 (2nd Port) that are associated with the
Serial port COM1 and COM2, respectively. After the application program connects to the TCP port 4660
(or 4661) on the PC-W, data of user’s application program are transparently transmitted to Serial port
COM1 (or COM2) of PC-W.

11

4. Application Connectivity

The PC-W is designed to transmit data between one or more Ethernet/serial devices to/from one or more
TCP/IP devices through wireless Ethernet interface. PC-W can enhance the accessibility of the serial
device through TCP/IP based Ethernet as well as Wireless Ethernet. The connection distance limit is
overcome by PC-W. Examples of these devices are PLC controllers, card readers, display signs, security
controls, CNC controller, etc.

4.1. TCP & UDP Protocols

PC-W can operate in two most common transportation protocols, TCP and UDP.

4.1.1. Transmission Control Protocol (TCP)

TCP provides a connection and a byte oriented data stream with control parameters such as flow control,
multiple ports option, and order delivery notification. Once the connection is established, data can be
transmitted in both directions. TCP guarantees data is transmitted from one node to the other node(s) in
orderly. The protocol also distinguishes the transmitted data for different applications (such as a Web server
or an Email server) on the same computer.

For redundant or dual-network connectivity purposes, PC-W offers two TCP operation modes so users may
choose for their specific application, TCP Server Mode and TCP Client Mode.

4.1.2. User Datagram Protocol (UDP)

UDP is a faster datagram delivery protocol. User can configure PC-W to work in the UDP mode. UDP is
connectionless protocol and can transmit multicast data to/from a serial device to one/multiple host
computer. Because UDP is the connectionless protocol, UDP does not guarantee the reliability and orderly
data streams like TCP protocol. Datagram may arrive out of order or lose without notice. But the advantage
of UDP is the speed. UDP is faster and hence more attractive in time-sensitive applications.

4.2. Connectivity Topology

PC-W is also equipped with Tunneling and Virtual COM operation modes. It is designed to transmit data
to/from multiple serial devices and from/to multiple TCP/IP devices on Ethernet, so it can enhance the
accessibility of the serial devices immensely. The example of PC-W connection topology is shown in Fig. 4.

Note: Please do not connect more then one device on Ethernet port

Fig. 4. Typical Topology of PC-W Connection

12

4.3. Ethernet to WLAN Bridge Function

The PC-W can also work as a network bridge between Ethernet to WLAN. Packets from WLAN to Ethernet
or from Ethernet to WLAN are transferred transparently. This will let the Ethernet devices can be accessed
from wireless networks over the wireless interface.

4.4. Virtual COM Mode

The Virtual COM software emulates a serial port in LAN topology. In the Virtual COM Mode, COM port data
is encapsulated with Ethernet data format. By creating a virtual COM port on a PC, the Virtual COM driver
redirects communications from the virtual COM port to the destination IP address (and the designated port
number) by encapsulating COM data into IP packet format. Fig. 5 illustrates a Virtual COM connection
diagram.

Fig. 5. TCP Connection in Virtual COM Mode

4.4.1. TCP Server in Virtual COM Mode

PC-W can be configured in the TCP server mode (PC acts as a client) with a unique IP and Port number,
and PC-W waits passively for the PC to establish a connection. After the connection is established, PC can
communicate to serial devices through PC-W.

Configure PC-W to be TCP server

Using one of the two configuration methods, by Web-based and by Windows-based Serial Manager utility,
Users can configure PC-W to be a TCP Server as follows.

 Disabled the IP filter (default)

 Set the port number (default port is 4660 for COM1, 4661 for COM2).

 If IP filter is enabled, only the assigned source IP is allowed to be connected to PC-W.

4.4.2. TCP Client in Virtual COM Mode

PC-W can also be configured in TCP Client mode (PC as a server) to establish a TCP connection to an
application server on PC, or the Remote Control Host. Once the connection is established, PC or Remote
Control Host can exchange data with several serial devices at the same time through PC-W as shown in Fig.

6.

13

Configuring PC-W to be TCP client

User can configure PC-W to be as a TCP client, for example, from Fig. 7, PC, as a server, has IP address

10.0.0.100 and listening on port 1000. Each PC-W, connected with serial device, configured as TCP client
mode with destination IP address 10.0.0.100 and the destination port 1000, and the IP filter is disabled (by
default).

Fig. 6. TCP Server in Virtual COM Mode

Fig. 7. TCP Client in Virtual COM Mode

4.5. Tunneling Mode

Tunneling Mode is used for multiple serial devices to “talk” among one another through PC-W’s wireless
LAN or wired Ethernet interface. This mode is particularly useful when two or more serial devices are far
away. This mode can be used to extend the normal RS-232 serial communication distance of 15 m to 100 m
or longer as shown in Fig. 8.

14

One PC-W can be configured to be the TCP Server Mode with serial device connected and also another
PC-W is configured as TCP client with serial device connected. After the connection is established, both
serial devices can exchange data to each other transparently. For example, users can implement PC-W
tunneling mode for Master /Slave mode PLC’s or between other serial devices.

Fig. 8. TCP Link in Tunneling mode

Configuring PC-W to Tunneling Mode

Using one of two configuration methods (Web-based or Windows-based Serial Manager utility), users can
configure PC-W to TCP Server mode with a desired IP address and port, and with other PC-W is configured
as TCP Clients mode with Server IP and port as destination IP and port respectively as shown as an
example in Fig. 9.

Note: TCP client has to assign the destination IP and the destination port corresponding to TCP
server’s IP and listening port (example: TCP 4660 port).

Fig. 9. TCP Tunneling Mode

4.6. UDP mode

In UDP mode, users may exchange Multicast data from one PC-W with multiple PC-W devices as shown in
Fig. 10.

15

Fig. 10. UDP Link in Tunneling mode

Configure PC-W in UDP Mode

Use one of the two configuration methods (Web-based or Windows-based Serial Manager Utility). Users
can configure PC-W to UDP mode. In UDP mode, PC-W can be configured to communicate to more than
one node (Multicasting). Note that the Multicast IP address is limited by the Class of IP address and subnet
mask. As an example, for a network of Class C of subnet 192.168.1.X and a subnet mask of 255.255.255.0,
the maximum Multicast IP address to be configured is four destinations IP’s.

Fig. 11. Multi-UDP Link in Tunneling Mode

5.5. COM Port Configuration

Users can configure Serial parameters including UART mode, baud rate, parity, data bit and type of flow
control and the mode of operations, which are TCP Server, TCP Client, and UDP modes. The COM Port
Configuration page is shown in Fig. 26.

5.5.1. TCP Server Mode

TCP Server mode is the default Link mode of Serial Settings as shown in Fig. 27. In this mode, the
connection waits for a connecting requirement from a remote host PC which is running a “Serial to IP” utility
or setting PC-W in tunneling mode. Users need to configure a listening port to allow clients establishing a
connection to this server. Default port number of COM1 is 4660.

IP filtering function is a simple ACL (Access Control List) for incoming IP packets. It can be disabled by
setting Source IP to “0.0.0.0”. Users can configure one or a group of IP address for Source IP. If IP filter is
enabled, only source IP assigned can be connected to PC-W.

Note: Enable Virtual COM mode if the remote site PC’s “Serial to IP” tool is installed

5.5.2. TCP Client Mode

Users may enter a Destination IP and Destination port (default: 4660) to establish a connection of
counter-pair (remote) host (for example, another PC-W or PC for data collection) as shown in Fig. 28. PC-W
can support up to two destination hosts simultaneously.

26

Fig. 28. TCP Client in Link mode

5.5.3. UDP Mode

PC-W can be configured in a UDP mode to establish connection using Unicast or Multicast data from the
serial device to one or multiple host computers as shown in Fig. 29. Vice versa is also true. For example,
the original RS-422/ RS485 bus can be transferred and extended connection distance by PC-W.

The destination IP is assigned by a single IP or a group of IP addresses. The configuration is limited by the
Local Listening Port. For example, the PC-W listening port is 4660 which receives data sending from the
host computers. PC-W can support up to 4 group IP addresses for UDP connection, if users needed.

Note: In UDP mode, the device does not support Virtual COM mode.

Fig. 29. UDP protocol in Link mode

 Stop bits: 1 or 2

28

 Flow control: None or Xon/Xoff or Hardware (RTS/CTS).

Fig. 30. Serial Communication Settings from Web Page

5.5.5. Packet delimiter

Packet delimiter is a way of controlling the number of packets in a serial communication. It is designed to
keep packets in track. PC-W provides two ways in parameter setting: (1) Packet delimiter by timer and (2)
packet delimiter by Character pattern. By default, packet delimiter timer is 10 ms. the range of packet
delimiter timer is 10 to 30,000 ms. For Character pattern terminator, if a character pattern is selected and a
data stream ended with “0x0a04”, then the entire data buffer of the serial device is transmitted.
