1. Overview
1.1. Introduce
01
ULNA CPE988 is a long-distance 5.8G wireless transmission device. It uses
wireless communication technology to transmit network data using air as a
medium to perform long-distance point-to-point or point-to-multipoint
interconnection. The working data link layer realizes the interconnection of
local area networks. The transmission distance can reach up to 5km.
CPE988 Video Bridge Transmission usually consists of two devices in AP and
Client mode respectively. On the Client-side (Receiving side) CPE connects
with IP Camera, at the AP side (Transmitting side) CPE connects with a video
recorder. The AP can be receiving wireless data transmitted from multiple
Clients, and it is easy and convenient for centralized management of the
remote equipment.
CPE is widely used in highways, reservoir river monitoring, elevator monitoring
systems, site crane monitoring systems, port terminal monitoring systems,
marine aquaculture monitoring systems, and so on.
Point to point extend network WiFi range, extend the network in the house to
your barn, garage, church, warehouse, and even neighbor's house through
wireless bridge signal transmission. No need to install a new modem and pay
for it every month, saving you money.

5. Quick Start
5.1 PoE Power Supply
The CPE988 wireless bridge adopts a PoE power supply, which is easy to install
and manage while saving costs.
5.2 Point to Point Pairing Step:
1. Switch one unit to A(Master Bridge) and one unit to B(Slave Bridge)
2. Connect the POE to each unit using the Ethernet cable and plug the POE in;
3. Wait for them to power up, about 2 min;
4. Use the tiny reset button to click through until you get a channel with a letter.
1,2,3,..., A,B,C,...,F, here used C;
5. Then on the other unit do the same. Both units need to be on the same
channel;
6. Wait for 2-5 minutes to complete the pairing. When the number of the digital
tube is solid and the signal light on the side turns on, it means the pairing is
successful;
7. Finally connect other devices(Router, PC, Switch) and install them to the
target location.
（TIPS: Steps 1, 4 and 5 are already pre-set at factory）
1.1. According to the requirements, prepare a long enough network cable
（Recommended within 20 meters, must Cat 5e or up）to connect the
wireless bridge and the PoE power supply. The PoE port of the PoE power
supply is connected to the WAN port of the wireless bridge.
1.2. The LAN port of the PoE power supply is connected to the PC, router, and
switch.
6. Installation

6.1 Pole mount
5.3 Point to Multipoint Pairing Step:
e.g. 1 master bridge with 3 slave bridges
1. Switch one unit to A(Master Bridge) and 3 units to B(Slave Bridge);
2. Connect the POE to each unit using the Ethernet cable and plug the POE in;
3. Wait for them to power up, about 2 min;
4. Use the tiny reset button to click through until you get a channel with a letter.
1,2,3,..., A,B,C,...,F, here used C;
5. Then on the other 3 unit do the same. 4 units need to be on the same
channel;
6. Wait for 2-5 minutes to complete the pairing. When the number of the digital
tube is solid and the signal light on the side turns on, it means their pairing is
successful;
7. Finally connect other devices(Router, PC, Switch) and install them to the
target location.

1. Choose to pole mount or wall-mounted, adjust the CPE orientation, the
bracket is not included in the package. Recommended ULNA Universal
Bracket (ASIN: B0B5TWYHWC).
2. Prepare a long enough network cable to connect the PoE adapter and CPE,
the network cable is connected to the LAN port of the CPE, and the other
end is connected to the PoE port of the PoE adapter. Recommend to use a
cat 5 (or above) shielded network cable with a ground wire.
3. Connect the PoE adapter PoE to CPE, and LAN to Camera, PC, Router or
Switch based on the network topology. The role of PoE is to provide power
and data transmission for CPE.
4. The master CPE’s PoE adapter’s LAN connection monitors the Internet, and
the slave CPE’s PoE adapter LAN connects cameras or routers and other
equipment.
Note:
For point-to-point installation, the line of sight of the 2 wireless bridge brackets
must be clear and cannot pass through the wall. The signal transmission angle
of the bridge is 60 degrees. For point-to-multipoint installation, the angle of the
slave bridge needs to be adjusted to ensure that it is within the 60-degree
signal range of the main bridge. The antenna polarization direction is horizontal
60°/vertical 30°.
1. The WiFi function is turned on by default for the master bridge. The slave
bridge is unable to provide WiFi, it is recommended to connect a new router.
WiFi SSID: CPE5G-5GXXX
WiFi PWD: zllinkcpe123456XXX
XXX represents different channels, please refer to the comparison table in
the user manual.
2. You can access the wireless bridge through your computer to set the SSID
and new WiFi password. Please refer to the advanced settings section.

8.4 Case 4: Point-to-point extended surveillance cameras
range
Note: You can work the wireless bridge without advanced settings
1. Computer Access Wireless Bridge, connect the CPE to the computer Refer to
the figure left to connect the CPE to the computer through a PoE adapter and
an Ethernet cable.
2. Modify your computer's IP address, make your computer's IP and the
bridge's IP address be on the same network segment(LAN) so that you can
access them.
3. Change your computer's IP address to 192.168.255.xxx
(192.168.255.xxx cannot be the same as the IP of the CPE), then the entry IP
address is 192.168.255.xxx, the subnet mask is 255.255.255.0(Autofill), the
Default gateway is 192.168.255.xxx, Preferred DDS server 192.168.255.xxx.
You can use 192.168.255.105(xxx=2) in the reference picture to set.
Step 1: Find and open "Open Network and Sharing Center" on your computer.
Tips: click the network icon in the lower right corner of the computer.
Step 2: Find and open the "Change adapter settings", select "Local Area
Connection" to right-click to open the network properties. Refer to the picture
above to open.
Step 3: Find and double-click open the "Internet Protocol Version 4(TCP/IPv4)",
choose the " Use the following IP address" and enter IP address, subnet mask,
Default gateway, Preferred DDS server.

4. On the login screen, the default user name and login password of the
wireless bridge is "admin", just entry password login.
Note:
“admin” is not the password of the WiFi SSID, it is just the password for WEB
access.
5. Login successful, go to setting.
6. When you want to change “SSID” information and password, please turn off
“Digit on/off” first. And then turn off "Hide SSID" and modify the SSID name and
WiFi password, and finally click "Apply" to complete the setting.

Packet Latency
1. Wireless interference
2. Distance is too long,
or there are some walls
between them
3. CPE's angle in the
wrong direction,
weak signal
1. Use WiFi analysis to
choose the best channel
2. CPE should be in the
normal distance, and avoid
the wall
3. Adjust the angle of CPE
according to signal strength
Wrong Password
1. Forget the password
2. Input wrong password
3. Too much cookie
4. WiFi password is
confused with the WEB
access password

10s to reset the bridge, the
default password is admin.
2. Re-input the password
3. Clear cookie, run arp-d to
clear MAC table
4. WEB access user name
and password is "admin"
Can not login WEB
1. Local IP is not in the
same network segment
of CPE
2. IP is taken by other
devices
3. LAN connection or
