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.
