Screw the sealing onto the gland and tighten.
Ground the wire
The SGT-LD-5-23 is shipped with a grounding wire. The unit must be properly grounded to
protect against power surges. The grounding point can be found on the bottom of the unit.
It is supplied with an appropriate grounding lug for attachment to the ODU (Outdoor Unit).
Power On
To power up the SGT-LD-5-23, follow the steps below:
Plug a user-supplied Cat-5 Ethernet cable from your wired LAN (or a computer) into
the power injector RJ-45 jack (DATA IN);
Plug a user-supplied Cat-5 Ethernet cable from the SGT-LD-5-23 into the power
injector RJ-45 jack (P+DATA OUT);
Connect the power module to the power injector and plug the AC cord into an AC
power receptacle.
After being powered on, the device will send out the beep sound lasting about 1.5
seconds, informing you that the SGT-LD-5-23 is powered up. Wait for about 60
seconds - the system will be initialized and start working.
Make sure that the PoE is correctly connected to the RJ-45 port on the SGTLD-5-23 labelled PoE+Data. DO NOT connect to the port labelled “Warning!!
No POE”, otherwise the SGT-LD-5-23 will be severely damaged!
Chapter 4 Configuration
Connect the SGT-LD-5-23 to a Local Computer
If you are configuring the SGT-LD-5-23 locally (without connecting its power injector to a
wired LAN), connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet
1. Assign a static IP address to your PC, which is in the same network segment as the
SGT-LD-5-23. As the default IP address of this unit is, you may choose
from to
2. Test the link status between your PC and the SGT-LD-5-23. Start a command prompt
and execute a continuous ping command “ping –t”. If pinging to the wireless
bridge is successful (as shown below), open an Internet browser and enter the bridge’s
IP address in the address bar and press Enter.
Considering convenient configuration, it is recommended to configure local
and remote SGT-LD-5-23 respectively on two computers. TTL time may
vary depending on the operating system.
How to Establish Wireless Bridge Mode
The SGT-LD-5-23 supports four operating modes, which are Base Station, CPE, Peer-toPeer (CSMA) and Peer-to-Peer (TDMA). Normally, Wireless Bridge is the standard mode
on this unit. Here, we will illustrate how to establish wireless bridge connectivity with the

able to be opened. You may then choose to continue to the web interface of the unit.
Open “Basic Setup” in “System”, set the IP address of two SGT-LD-5-23’s to be in the
same network segment. e.g. local SGT-LD-5-23 as and remote SGT-LD-5-23
as and set the IP Subnet Mask on both as
Each IP address must be unique within a LAN, otherwise IP collisions may occur.
Open “Radio” in “Wireless” and you will find the default operating mode is Peer-to-Peer
(CSMA). Select to use the Peer-to-Peer (CSMA) operating mode and keep the
Channel/Frequency and Bandwidth on both SGT-LD-5-23’s identical. Click “Apply” to save
Login to the Web-based interface of the remote SGT-LD-5-23, open “About” in “System”
and record its wireless MAC address.
Login to the Web-based interface of the local SGT-LD-5-23 and open “Peer-to-Peer
Setup” in “Wireless”; input the WLAN MAC address of the remote one into the “Remote
MAC Address 1” field and click “Apply”;
The MAC address on the housing of SGT-LD-5-23 is the ETH MAC
address; therefore it cannot be used in Peer-to-Peer links. The IP
address of your PC should be in the same network segment as the one of
the bridges.
Use ping to check if the link between the two SGT-LD-5-23 is connected.
To get a better wireless connectivity, antenna alignment is strongly recommended after both
SGT-LD-5-23’s are installed a long distance apart. Login to the Web-based interface of the
local SGT-LD-5-23 and open “Peer-to-Peer Setup” in “Wireless”. Hit “Align Antenna”
button - an antenna alignment tool will pop-up. Specify the Target RSSI and click “Start” to
begin the antenna alignment.
Fix the local antenna and adjust the remote antenna elevation and horizontal direction.
During the adjustment, observe “Current RSSI” in the local SGT-LD-5-23. Fix the remote
antenna when it reaches your expected RSSI. Usually, a RSSI between -60 and -70dBm
indicates rather good signal strength.
Adjust the local antenna after fixing the remote one. During the adjustment, observe
“Current RSSI” in the remote SGT-LD-5-23. Fix the local antenna when it reaches your
expected RSSI.
Congratulations! You have completed configuration of the SGT-LD-5-23’s and they can be
put into operation. For more advanced configurations, please refer to the User manual.
Chapter 5 Troubleshooting
This chapter provides troubleshooting procedures for basic problems with the SGT-LD-5-23.
Q 1. What if my SGT-LD-5-23 fails to connect to the remote one?
Ethernet Link: Check the availability of power to the bridge by observing the LED
status on the power injector - Green: The SGT-LD-5-23 is connecting to the backhaul
network. -Off: The SGT-LD-5-23 is disconnected from the wired network; check if the
power cord and Ethernet cables to the network and bridge are correctly connected.
Basic Configurations: Mismatched basic settings among bridges are the most
common cause of connectivity failure. If the bridge does not associate with a remote
bridge, check if options in each device are identical.
Security Settings: Remote bridges attempting to authenticate to your SGT-LD-5-23
must support the same security options configured in your bridge, such as WEP and
WPA (2)-PSK. If your bridge fails to associate with others, check if the security settings
are the same as your bridge settings.
Antenna Alignment: If the methods above are all checked to be correct, you can
observe and verify antenna alignment with RSSI value.
Q 2. What if I would like to reset the unit to default settings?
You may restore factory default settings in “Backup/Restore Settings” from
Q 3. What if I would like to backup and restore my configuration settings?
You may do the backup by generating a configuration file or retrieve the settings you
have backed up previously in “Backup/Restore Settings” from “Management”.
