1. Introduction
1.1 Overview
The WG8010 is a compact, stand-alone wireless IP (GSM/GPRS) modem, which can be
used to connect any traditional serial (RS-232/485/422) device to a cellular network. The
WG8010 IP Modem comes pre-installed with the TCP/IP protocol suite to transmit data
back and forth between the serial device and GSM/GPRS network.
Traditional SCADA and data collection systems rely on serial ports to collect data from
various kinds of instruments, such as PLCs, meters, and sensors. Since the WG8010 IP
Modem network-enables instruments equipped with an RS-232, or RS-485
communication port, SCADA and data collection system will be able to access all
instruments connected to a standard TCP/IP network, regardless of whether the devices
are used locally or at a remote site.
The WG8010 IP Modem allows you to expand a serial port for a host computer on
demand. As long as your host computer supports the TCP/IP protocol, you will not be
limited by the host computer's bus limitation (such as ISA or PCI), nor will you be limited
if you do not have drivers for various operating systems.

3. Pre-Deployment Considerations
3.1 Cellular Network Connection
APN
APN (Access Point Name) is the point where a mobile device can enter an IP network.
Operator offers a public APN, letting all customers access the internet, and private APNs for
direct access to a company LAN. Private APN settings can be customised to authenticate
users and even to provide monitored internet access via the company’s web proxy.
3.2 Data Center IP address
Public Fixed IP Address
Mobile applications require a routable or “reachable” Data Center IP address. One way to
accomplish this is with a public fixed IP address, which is generally reachable by anyone on
the Internet.
Dynamic Domain Name
The demand for public IP addresses continues to grow, yet there are a finite number of public

WG8010 Cellular IP Modem User Guide
Page 8 of 18
IP addresses available. To solve this problem, wireless carriers have resorted to handing out
dynamic IP addresses instead of static or fixed public addresses.
With dynamic IP addresses, each device is given an IP address for a limited period of time
(usually no more than a few hours), and then the IP address is changed.
A Dynamic Domain Name Services (DDNS) server maps a static hostname to the remote
device, so that no matter how often the IP address of that device changes, the hostname still
points to the same device.
3.3 Operation Modes
Transparent Mode
A key feature of the WG8010 is a plug-and-play Transparent Operating Mode, which is
perfect for retrofitting installed legacy devices with IP capability.
Once the Transparent mode is established, the link becomes a pipeline for streaming raw
serial data to WG8010. Data will continue to flow freely between the local and remote devices
until a predefined activity occurs to terminate the remote connection.
Transparent with Device ID Mode
Device ID: User assigned ID number for the WG8010.
If this parameter is enabled, every time when the socket is connected, WG8010 will
immediately report its device ID
COMWAY Manage Mode
Before deploying wireless devices in the field, consideration must be taken on how those
devices will be maintained and monitored. Sending technicians onsite to check status, or
modify a device’s configuration can be both expensive and time consuming.
COMWAY Manager is a server-based software toolset that eliminates these problems and
provides the following features:
• Ability to view all devices securely from anywhere
• Batch configuration changes to one device or a thousand devices
Virtual COM Mode
In addition to providing socket access, this enables you to preserve your existing
COM/TTY-based software without needing to invest in additional software.
The WG8010 IP Modem comes bundled with COMWAY drivers for Windows systems;
the bundled drivers are able to establish a transparent connection between a host and a
serial device by mapping the serial port on the WG8010 IP Modem to a local COM port
on the host computer.
The WG8010 COM driver intercepts data sent to the host's COM port, packs it into a
TCP/IP packet, and then redirects it to the Internet. At the other end of the connection,
the Host accepts the IP frame from the cellular network unpacks the TCP/IP packet, and
then transparently sends the data through the serial port to the attached serial device.

3.4 Transmission Protocol
Data coming from a remote Device is packetized by the WG8010 and sends it via TCP or
UDP to a remote host. The main difference between the TCP and UDP Socket protocols is
that TCP guarantees delivery of data by requiring the recipient to send an acknowledgement
to the sender. UDP does not require this type of verification, making it possible to offer faster
delivery.
TCP
In TCP mode, the WG8010 IP Modem can actively establish a TCP connection to a
pre-defined host computer when serial data arrives.
As illustrated in the figure below, data transmission proceeds as follows:
(1) The WG8010 IP Modem, requests a connection to the host.
(2) Once the connection is established, data can be transmitted in both directions
between the host and the WG8010.
UDP
Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you
can unicast to one or multicast to multiple serial devices. These traits make UDP mode
especially well suited for message display Applications.

form data package
5.3 Flexible Connection
The WG8010 IP Modem can be configured for one of four network connections:
always-on, wake-up on ring, dial-on demand, or on schedule.
Always on
The always-on network connection automatically establishes a wireless data connection
and allows for around the clock surveillance, monitoring or real-time data acquisition of
any remote device. If the data link is dropped in the event of poor reception or a
complete loss of service, it will automatically re-establish the data link
Keep-alive message:
Keep-alive period (default=15 minutes):
A periodic “keep-alive” or heart-beat message is sent from the device to the server to
update its current status. This small amount of traffic (typically about 160-170 bytes) will
refresh the carrier’s inactivity timer, thus helping maintain the persistent wireless
connection. The keep-alive period is by default 15 minutes, but can be changed
according to need.
Wake-up on ring

WG8010 Cellular IP Modem User Guide
The configuration allows the modem to “wake up” and initiate a connection when it
detects an incoming ring. For security reasons, you can setup the modem to wake up
based on the caller ID. This configuration is ideal for reducing the costs associated with
the WG8010 being online and available 24/7
Auth type (default=none): To allow Caller ID Authentication
Caller ID (1 through 4): Phone number should be specified.
If you don't use Caller ID authentication, the WG8010 IP Modem will allow all incoming
short messages as serial data to be forwarded to its serial port. This includes system
broadcasts and advertisements.
Dial-on demand
When configured for dial-on demand, the cellular modem only accesses the Internet
when data is present.
On schedule
5.4 Others
Hardware Reset Threshold
Hardware reset thresholds will proactively reset the IP modem if the device fails to
connect for any reason. This adds an extra level of robustness to the connection
attempts.
By default, the mobile interface reset is set to 3 failed attempts.
Save Configuration
To save your submitted configuration changes to the WG8010 IP Modem's flash memory.
Page 17 of 18
