1.1 Brief Introduction
ER-800 is a high speed WCDMA 3G router. It works in China Unicom's
WCDMA network, can access internet and transfer video and data with
high speed.
Comparing with eTung’s MR-900W 3G routers, ER-800 has extended 4
Ethernet interfaces, and can connect 4 PCs via Ethernet cable at the
same time. Thus when customers have multiple PCs at the spot that
need to access the internet, they do not have to deploy additional hub
or wireless communication devices. This can reduce device
procurement cost and maintenance cost as well.
ER-800 has WIFI functionality as well, and supports 802.11b/g/n
protocol. In theory the highest speed can be 150Mbps. Either mobile
phones, PCs or other devices that has WIFI functionality, can bind
ER-800’s WIFI access point and share Internet access via ER-800. This
greatly extends the number of devices that can connect with ER-800 at
the same time. Meanwhile, with ER-800’s WIFI and extended Ethernet
interfaces, customers can build a small local area network, and all
devices that connect to ER-800 via WIFI or physical Ethernet cable are
in the same local area network, and can communicate each other freely.
ER-800 has built-in WEB configuration interface, and is easy to use.
ER-800 User Manual
ER-800 supports static routing, DMZ host, port forwarding and VPN,
and has performance tuning function for high speed wireless
applications as well. It can work stably and reliably in unattended
environment.
In theory the uplink speed of data transfer is 5.76Mbps, and downlink
speed is 21Mbps. ER-800 can connect quickly with web camera, video
server, PLC and IPC, and transfer data from the customer device that
connects with ER-800 to a host in the internet, so as to transfer data
remotely and transparently. ER-800 can be widely used in industries
such as banking, road transportation, power system, environment
protection and industrial controlling.

PC connects to one of ER-800’s Ethernet interfaces with a cross cable.
After power on it dials via 3G wireless network and connects to the
internet, then PCs can share the internet via ER-800, and access the
application server. At the same time, using ER-800’s WIFI
functionality, PCs (or other devices that support WIFI) can connect to
ER-800’s WIFI access point, instead of connecting with Ethernet cable,
to share the Internet access. Meanwhile, ER-800 can be used to build
remote virtual LAN with Virhub or VPN, monitor video remotely, and
publish programs remotely on LED color screens, etc.

2.5 Remote Configurations
SMS commands and remote AT commands can be used on ER-800 to
modify configuration parameters remotely. Details are described
below:
1. Modify configuration parameters remotely via SMS
The SMS to configure ER-800 parameters should follow the format
below: SMS password;AT commands
1) SMS password is the "SMS wakeup password" as shown in
wireless network settings of the web configuration interface,
with "1234" by default. This password is used to filter rubbish
SMS. Long SMS is not supported.
2) There can be multiple AT commands, and ";" is used between
SMS and AT command, and between AT commands. If there are
more than one AT command and some command fails, the
following commands will not be executed. If a command is
unknown, an ERROR will return. The commands will take effect
after system reboot. This can be done by putting a command
"AT+REBOOT" in the end of SMS commands, or sending a
separate SMS with command "AT+REBOOT".
3) AT command must be capitalized, but the parameters in the
command do not have this limit.
4) If there are multiple parameters in the command, just write
those that need to change and you do not have to write all of
them. If some item does not need to change, write two
continuous colons, and if some item needs to clean, write a
space. For example:
AT+WN=3gnet (configure onely APN, and other parameters keep
unchanged)
AT+DC=,,user (the first two items keep unchanged, and change
username only)
For remote SMS configuration, the contents of SMS must be English
charactes or digits in single byte, and can not be in double byte.

5. Access the wireless router remotely via Virhub
ER-800 V1.0.6 or higher version has functionality of accessing the wireless
router remotely via Virhub. Normally, the router dials up into the wireless
network and gets an inner IP address, and it cannot be accessed from the
internet via this inner IP. eTung’s Virhub solution can solve the problem.
First, enable Virhub function on the router, and set a remote access IP; the
39
ER-800 User Manual
remote access IP is dedicated to access the router remotely when Virhub is
enabled on the router. Then run Virhub software on the far-end PC, and
configure an IP address on the Loopback adapter; this IP must be in the
same range as the remote access IP on the router. This way, we can access
the router remotely on the far-end PC via the remote access IP, to perform
configuration, system monitoring, etc. Below are the details about the
configuration procedure.
1) Configure the router’s remote access IP
According to “2. Configure Virhub Parameters”, go to the router’s
Virhub configuration, enable Virhub and configure username, then
there are two parameters: “Remote Access IP” and “Remote Access
Mask”, with default values: 192.168.168.1 and 255.255.255.0.
Figure Appendix 2-6: Configure the router’s remote access IP
Normally set the two parameters with default values, and they can also
be changed on demand. Press “Save” after configuration, then reboot
the router. These two parameters can also be changed/checked via
remote AT commands, please refer “2.5 Remote Configurations”.
2) Configure the Loopback adapter’s IP address to access the router
remotely
Run Virhub software, click button “Configure”, and on the popped up
“Settings” dialog, set the Loopback adapter’s IP address in “Loopback
Adapter IP Settings” part. IP2 is the IP address set on the Loopback
adapter to access the router remotely via Virhub, and this IP must be in
the same range as the “Remote Access IP” (192.168.168.1 by default)
set on the router in step 1), for example, 192.168.168.*.

Appendix 3: APN Network Testing
Case
APN is the abbreviation of Access Point Name. It is used in operators’ core network
to identify the external data network, for example, enterprise intranet, Internet,
WAP website and enterprise’ internal networks. Using the APN SIM card, the
terminal dials up into a dedicated network predefined from the operator side, and
normally gets an internal IP address to access the network, this IP address cannot
be accessed from the internet. But the terminals that dial into the same dedicated
network can access each other. So we can easily implement the interconnection
between wireless terminals with operator’s APN networks, it’s very convenient and
can greatly reduce network access cost. There are two kinds of solutions to use APN
networks, and below are details for each of them.
Solution 1: Embedded Data Center with APN Network
eTung’s wireless routers support APN SIM card, and has embedded data center
function. For those small-scale projects with few terminals, use one router as the
data center, and dial into APN network; at the same time, all other terminals that
connect to devices at the far end dial into the same APN network, then from the
router’s data center we can access the terminals at the far end, thus implement
remote control of devices at the far end. This solution is cost-efficient, and can be
easily deployed; it’s flexible and convenient, and can be used especially in
small-scale (No. of terminals <=100) device control projects.
Figure Appendix 3-1: Embedded data center and APN network solution
Below we will illustrate how to deploy this solution, and use MD-609G as an
42
ER-800 User Manual
example for terminals at the far end.
First of all, please order APN SIM cards from operator, and parameters include APN
name, PPP username and password, and for the SIM card used by the router there
should be a static IP address assigned as well.
1. Configure APN parameters in the router
According to the description of “2.1 Configurations”, login in the configuration
web page, Choose “Wireless Net”->”Simple Cfg”, and then select “Manual Set”
for APN Mode, configure APN name, and PPP username and password if
required. click “Save” and then reboot the router to apply the change.
Figure Appendix 3-2: Configure APN parameters in the router
2. Configure Embedded Data Center in the router

web
page,
choose
“DTU
Function”->”Embedded DC”, enable embedded DC, set transport protocol as
TCP, center port as 9000, and set the maximum number of terminals as
required, at most 100, and then click “Save” and reboot the router.
43
ER-800 User Manual
Figure Appendix 3-3: Configure embedded DC in the router
After the router reboots and dials up into the APN network, in configuration web
page “Status”, we can check the IP address assigned by APN network.
Figure Appendix 3-4: Check the IP address acquired from APN network
3. Configure data center address and APN parameters in DTU
Run wireless configuration software dtucfg.exe, power on DTU according to the
prompt and then enter the configuration menu. For the 1st item: mServer
DN/IP Addr, set as the static IP address acquired by the router from APN
network, for example, 10.8.224.81; for the 2nd item: mServer Port, set as 9000;
for the 4th item: APN, set as the APN name; for the 5th item: Protocol, set as
TCP that is the same as the transport protocol configured in the embedded data
center; then press Enter until Dial Account and Password, set as PPP username
and password of the APN SIM card as required.

ER-800 User Manual
Figure Appendix 3-5: Configure DC address and APN parameters in DTU
After that press Enter until the serial port parameters: baud rate, data bits,
parity, stop bits and flow control, the values for these parameters must be the
same as those set in the serial device that DTU connects to; and if they are not
the same, we can modify the values here in DTU to make sure they are the
same.
45
ER-800 User Manual
Figure Appendix 3-6: Configure DTU serial port parameters
After configuration is finished, reboot DTU to dial up into APN network, it will
then automatically connect to the router’s embedded data center; in the
router’s status page, we can see that one device has connected the embedded
data center.
Figure Appendix 3-7: Status shows DTU has connected to embedded DC
4. Device at the front end receives/sends data via serial port
46
ER-800 User Manual
After configuring router and DTU at the far end, both dial up into the APN
network, and DTU connects to the embedded data center running in the router;
then we can receive data from the serial device at the far end via the router’s
user serial port, and at the same time device at the front end can send data to
the device at the far end via the router’s user serial port. Pay attention, the
front-end device broadcast data to all the far-end devices, so there should be
identity in the data packets sent/received between front-end and far-end
devices to distinguish from/to whom the packets are received/sent.
Solution 2: mServer Connects the Router and with APN Network
For large-scale projects with lots of terminals, this solution: mServer connects the
router and with APN network can be used. As shown in the figure below, eTung’s
wireless router dials into operator’s APN network, and the data center at the back
end connects to the router with Ethernet cable; at the same time configure DMZ
host on the router, then terminals at the far end dial into the same APN network and
can connect to the data center at the back end. Compared to solution 1, this
solution can also be easily deployed and cost-efficient; at the same time since the
data center is running in a dedicated server, compared to embedded data center
solution, it allows more terminals to connect to the data center, and there can be
more flexible configurations, for example, map a virtual serial port for each
terminal, make point-to-point mapping between two terminals, etc.
Figure Appendix 3-8: mServer connects to the router and with APN network
Below we will illustrate how to deploy this solution, and use MD-609G as an
example for terminals at the far end.
First of all, please order APN SIM cards from operator, and parameters include APN
name, PPP username and password, and for the SIM card used by the router there
should be a static IP address assigned as well.
1. Install and run mServer in the data center server
Ask eTung for mServer installer, and install mServer according the user manual.
Make sure the firewall software allows accessing mServer from outside.
47
ER-800 User Manual
After mServer is installed, double-click mServer’s icon on the desktop to run
mServer console, choose “System Settings”, in tab “Service Settings”, choose
TCP for link mode, and set listen port as 9000.
Figure Appendix 3-9: Configure mServer
2. Configure APN parameters in the router
As step 1 in solution one shows, configure APN parameters in the router’s
configuration web page.
3. Configure DMZ host in the router
First, connect data center server to the router with Ethernet cable.
Then, set static IP address in the data center server, and the IP address must
be in the same IP range as the IP address of the router’s Ethernet interface, for
example, 192.168.1.*. The figure below shows the server’s static IP address is
set to 192,168.1.100, and gateway and DNS are set to 192.168.1.1.

ER-800 User Manual
Figure Appendix 3-10: Set static IP address
Login the router’s web configuration page, choose “NAT Rule”->”DMZ Host”,
then configure DMZ Host IP as the static IP address of the data center server,
for example, 192.168.1.100 as configured above.
49
ER-800 User Manual
Figure Appendix 3-11: Configure DMZ host
Click “Save”, and then reboot the router. Then data packets received by the
router from the outside network will be forwarded to the data center server.
4. Configure data center address and APN parameters in DTU
Configure data center address and APN parameters as shown in step 3 of
solution one. Set data center IP address to the IP address acquired by the
router after dialing into the network, and data center port as mServer’s
listening port, i.e. 9000 as shown in figure appendix 5-9.
After configuration is complete, reboot DTU, it will dial into APN network, and
then connect to mServer; in mServer’s console we can see that this terminal is
already online.

Appendix 4: Use ER-800 to Access
LAN Remotely via VPN
ER-800 can be used to extend and access the corporate virtual LAN remotely with
VPN function, for example, the user can use ER-800 to dial into corporate LAN. But
the router in user's corporate LAN should support VPN in this way. We will illustrate
below how to implement this kind of network connection with VPN.
1. System Architecture
Figure Appendix 4-1: Use ER-800 to access LAN remotely via VPN
2. Preparations
1) One router with VPN function(use PPTP protocol as an example), a LAN is
attached to this router and can access internet;
2) One ER-800(including accessories)
3) One USIM card with internet service(for example China Unicom wo)
4) One PC
3. Steps
1) Configure to use PPTP when accessing the router
Here we use router RV042 from Linksys as an example. First, this router
supports VPN and PPTP protocol. Login this Linksys router. and click
"VPN"->"PPTP", enable PPTP server and set the IP range for VPN
connection, then create username and password used for VPN connection,
as shown in the figure below:
52
ER-800 User Manual
Figure Appendix 4-2: Configure router's VPN function
Actually different routers have different configuration interface and options,
we can configure it accordingly.
2) Configure ER-800
Login ER-800's configuration interface, click "VPN function" and configure it
as shown in the figure below:
Figure Appendix 4-3: Configure account for VPN function
53
ER-800 User Manual
Type -- PPTP or L2TP
VPN server IP or domain -- the IP address on corporate LAN side, if the
IP address is not static, we recommend to apply a domain free of charge
from Oray or Gnway, then input the domain here, ER-800 supports domain
resolving.
Username -- the username configured in the router at corporate LAN side,
i.e. the username configured in Linksys router before;
Password -- the password configured in the router at corporate LAN side,
i.e. the password configured in Linksys router before;
VPN function -- ON, to enable VPN connection.
After all settings are complete, reboot ER-800.
3) Check dialing status
Login ER-800 to check dialing status, as shown in the figure below:
Figure Appendix 4-4: ER-800 status of accessing LAN
At this time, ER-800 is connected to the corporate LAN, and visiting
http://192.168.0.207 inside the corporate LAN can see ER-800's web login
interface, and at the same time ER-800 can access resources inside the
corporate LAN.
If we connect a video server to ER-800, and configure port forwarding or
DMZ host on ER-800, we can then access http://192.168.0.207 inside the
54
ER-800 User Manual
corporate LAN and then access the video monitoring interface.
Notes:
1） The IP address used by PC or video server that is connected to ER-800 must
not be in the same range as those IP addresses at the corporate LAN side.
For example, if the IP range at the corporate LAN side is 192.168.0.*, then
ER-800 should be in other IP range, for example 192.168.1.*.
2） ER-800 and the PC or video server that connects to it should be in the same
IP range. ER-800's default gateway is 192.168.1.1, and if the IP range of
the PC or video server that connects to ER-800 need to be 192.168.0.*,
then change ER-800's gateway to the same range, for example
192.168.0.1.
