1.3 Installation and Cable Connection
1.3.1 Installation of Antenna and SIM Card
The antenna interface of the equipment is a SMA female socket. Rotate the SMA male
head of the supporting antenna to the antenna interface of the equipment, and make sure it is
tightened, so as not to affect the signal quality.
When installing or removing the SIM card, insert the small yellow spot on the right side
of the SIM card seat with the spike and the SIM card holder will pop out. When installing
the SIM card, place the SIM card into the card holder first, and make sure the metal contact
surface of the SIM card is facing out, and then insert the SIM card holder into the drawer,
and make sure it is inserted in place.

1.4 Power Supply
The devices usually apply in the complicated external environment. To adapt to the
complication application environment, improving the stability of system, our devices adopt
advanced power supply technology. Users can supply the power for device with standard
+9VDC/1.5A power adapter, or with the 7~35V direct current. When users supply the
power with additional power supplier, they must guarantee the stability of power supply
(the ripple wave is less than 300mV, and ensure the transient voltages is less than 30V), and
please ensure the power is more than 4W.
Recommend the standard +9VDC/1.5A power supply.

2.1.4 Keep Alive
It’s a feature to detect the state of data transmission channel between RTU and Internet
in every few minutes automatically. If it detects an abnormal network state, RTU will restart
and re-dial automatically. This is used to achieve a function that router will keep online all
the time even if without administrator’s monitoring.
Please according to practical situation, type a reachable IP address in “Destination IP
1/2”. “Check Interval” and “Check Timeout” can be left in default value.
Notice:
a. If this function has been closed, then the RTU will not detect the network state, so
RTU will not restart and re-dial even if it’s offline.
b. The destination IP should be stable and reachable for RTU, for if destination is
unstable then it’ll cause the router to reboot constantly.
c. This function is used for public as default, so in private network, destination IP
should be modified.
2.2 Advance
2.2.1 Filter
It mainly used to filter wireless network data transmitting and receiving, to prevent
illegal and invalid data from gateway. It admits and refuses computers of LAN connected
with gateway to get access to WAN, or admits and refuses WAN to get access to LAN
connected with gateway.

Filter mode: Client IP filtering and MAC address filtering, client can select
according to their actual need.
Client IP filtering: Filter data according to IP address base on appointed policy to
admit or prevent corresponding IP address data.
MAC filtering: Filter data according to MAC address base on appointed policy to
admit or prevent corresponding MAC address data.
Running Rules: This device has two kinds running rules.
Discard matching following rule data packets: data packets comply to following
rules are not allowed to go through, other data packets can go through. Receiving matching
following rule data packets: only receive data packets comply to following rule, others are
discarded.
IP Filter
To realize IP address filtering rules appointing, revising and deleting.
Rule name：it is limited to use characters0-9.a-z.A-Z，also can’t repeat name.
LAN IP：Wireless gateway connected LAN IP address.
LAN Ports：LAN IP address host corresponding ports scope. Valid value is
0~65535, please input from small to large.
WAN IP：Data packet destination IP address.
WAN Ports：Data packet destination ports scope. Valid value is 0~65535，please
input from small to large.
Protocol: data packet protocol, here are 3 types:
ALL : All types data packet.
TCP : All TCP packet.
UDP : All UDP packet.
Direction：data packet direction, used to decide which is original address, there are 3

types.
IN : From outside network to gateway.
OUT : Transmit from gateway LAN.
IN/OUT: Include IN and OUT
Interface: Data packet go through interface, such as br0，PPP0 and so on.
Example 1 of IP address filtering:
1. If select “start client IP address filtering”
2. Running rules select: “discard packets matching following rules ”，click “Apply” to save
running rule.
Instruction: If select “discard packets matching following rules”, default rule is: wireless
gateway allows all data to go through, but not allowed data packet to go through.
3. Input parameters in IP rule.
This example parameter is:
Name：enableipfilter01
LAN IP：192.168.1.23
WAN IP：121.204.201.13
Protocol：all
Direction：IN
Interface：PPP0
Read picture 4-2-3，then click “submit” to save IP filtering rule.
4. Explanation and Introduction
After this rule built, gateway will start IP address filtering function.According to running
rule “Discard packet matching following rule”, gateway discards all protocol data packets
(select “ALL”) from WAN “121.204.201.13”(select “IN”direction) in PPP0 interface
(select “PPP0”interface), but other IP address data packets don’t comply to this rule can
come and go normally.

Example 2 of IP address filtering:
1、select “setup client IP filter”
2、Running rule: “receive packet matches following rules”, click “Apply” to save.
Instruction：if running rule select “receive packet matches following rules”, default rule is :

3. Input parameters in IP rule.
This example parameter:
Name：enableipfilter02
LAN IP：192.168.1.23
WAN IP：121.204.201.13
Protocol：all
Direction：IN/OUT
Interface：PPP0
Read picture 4-10-3，then click “Submit” to save.
4、Explanation and Instruction
After this rule built, gateway will start IP address filtering function. According to running
rule “Receive packet matching following rule”, gateway forbid all data packet to go
through, but only allow protocol data packets (select “ALL”) from WAN
“121.204.201.13”(select “IN/OUT” direction) to go through PPPO interface (select PPP0

16
interface). Usually this rule shields invalid IP address to go through gateway, can reduce
data flow, or as bank application, can shield other IP address access to bank IP address to
realize filtering functional and reduce data flow.
MAC Address Filter
Rule name：it is limited to use characters 0-9.a-z.A-Z，also can’t repeat name
MAC：Block or permit device MAC address, input format is“00:12:23:34:45:56”
Example 1:
1. If select “setup MAC address filtering”
2. Running rule select: “discard packet matching following fule ”
3. Input“00:00:23:34:45:56”in MAC.
So gateway will discard all data packet of MAC address “00:00:23:34:45:56”,
meanwhile permit all data packet which MAC address is not“00:00:23:34:45:56”to go
through.
Example 2 :
1. If select “setup MAC address filtering”
2. Running rule select: “receive packet matching following rule”
3. Input“00:00:23:34:45:56”in MAC.
So gateway only receive data packet which MAC address is “00:00:23:34:45:56”, and
discard all other data packet which MAC address is not “00:00:23:34:45:56”.
2.2.2 NAT/DMZ
NAT
The full name of NAT is “Network Address Translation”, also means port mapping. It’s

厦 门 才 茂 通 信 科 技 有 限 公 司
Xiamen Caimore Communication Technology Co.,Ltd
17
a technology that map private IP addresses to a WAN address’s different ports, which makes
devices in LAN can be accessed by Internet.
By setting these parameters, it’ll transfer the data from Internet to a specified host and
port in the LAN via port mapping.
Name: It’s used to identify different rules, so each name should be different. Please
name it with 0-9,a-z,A-Z, other characters will not be supported.
Protocol: There are three protocols can be chosen -- TCP, UDP and TCP/UDP.
External Port: WAN port.
Internal IP Address: The private IP address you want to map to external.
Internal Port: The port of internal host you want to map to external.
DMZ
In order to achieve the both-way communication, DMZ will expose a specified internal
host to Internet, that also means the host will play a role of virtual server. When there are
external users who wanting to visit the public IP address that mapped by the virtual server,
then router will transfer the data to virtual server directly.
If there is a host in LAN who wants to connect Internet directly, DMZ is a simple method to
achieve this purpose.
DMZ：Set form is to select “Start DMZ”directly, then input virtual server IP in the
IP address bar. Click “Apply”to save.
