Typical Applications
This section describes the typical applications of the SGT-LD-5-23.
Telemedicine Wireless Broadband Application
The SGT-LD-5-23 primary usage is as a relay or bridging technology that may be combined with a
cost-effective solar power solution allowing for telemedicine application in remote and rural
environments. The SGT-LD-5-23 is able to deliver stable and high performance broadband
connectivity for typical telemedicine applications in a Line-of-Sight environment.
Figure 2 Telemedicine Wireless Broadband
Chapter 1 Introduction Page 14
Education Wireless Broadband Application
Schools in remote or rural areas can be provided with broadband connectivity via local Internet service
providers. The relay ability of the SGT-LD-5-23 allows for multiple hops to be made thus allowing the
SGT-LD-5-23 to reach more remote LOS locations beyond 40km or to circumvent natural obstructions
like mountains.
Figure 3 Campus Wireless Broadband
Additionally, the SGT-LD-5-23 can also be applied for the following environments:
Cost-effectively provide long distance backhaul for remote areas (e.g. village, oil well, island,
mountain etc.)
Establish local backhaul for campus, farm and factory
Provide access for video streaming or surveillance for industrial and mining enterprises
Operates as a relay connecting different networks
Chapter 3 Basic Settings Page 15
Chapter 2 Hardware Installation
This chapter describes safety precautions and product information you have to know and check before
installing a SGT-LD-5-23.
Preparation before Installation
Professional Installation Required
1. Please seek assistance from a professional installer who is well trained in the RF installation and
knowledgeable regarding the local regulations.
2. The SGT-LD-5-23 is provided through distribution to system installers who employ services of
trained professional technicians – the SGT-LD-5-23 is not sold directly through retail stores.
3. The equipment shall be installed in RESTRICTED ACCESS LOCATIONS. Access can only be
gained by service persons or by users who have been instructed about the reasons for the
restrictions applied to the location and about any precautions that shall be taken. Furthermore,
access is through the use of a tool or lock and key, or other means of security, and is controlled
by the authority responsible for the location.
4. If you are intended to use an external antenna with the SGT-LD-5-23, please contact your
supplier/installer to ensure that your unit is set for you have fulfilled all the local regulatory
requirements. It is the responsibility of the installer/user to check that the equipment as
deployed meets local regulatory requirements.
Chapter 3 Basic Settings Page 16
Safety Precautions
To ensure your safety and to install the hardware properly, please read and follow these safety
precautions.
ONLY qualified service personnel should service or disassemble this device;
When installing the device, note the followings:
- Do NOT use a metal ladder;
- Do NOT work on a windy or raining day;
- Do NOT install, use or service the device during a thunderstorm, as this may cause a remote
risk of electric shock from lightning;
- Wear shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
- When the system is operational, avoid standing directly in front of the antenna. Strong RF
fields are present when the transmitter is on.
Ground the device properly with grounding wire to protect against lightning;
Use ONLY appropriate accessories for the device.
If the temperatures of the unit surface exceeds the limit, be precautious not to continuous hold or
touch the device for a certain period of time.
Installation Precautions
To keep the SGT-LD-5-23 well while you are installing it, please read and follow these installation
precautions.
1. Users MUST use a proper and well-installed surge arrestor and grounding kit with SGT-LD-5-23;
otherwise, a random lightning could easily cause fatal damage to SGT-LD-5-23. EMD
(Lightning) DAMAGE IS NOT COVERED UNDER WARRANTY.
2. Make sure PoE is correctly connected to the RJ-45 port on the SGT-LD-5-23 labelled PoE+Data.
DO NOT CONNECT TO THE PORT LABELED “Warning!! No POE”, otherwise the
SGT-LD-5-23 will be severely damaged!

DO strictly follow the instructions to avoid damaging your equipment!
Figure 11 Warning Label
Do NOT connect PoE powered Ethernet cable to the RS-232 port; otherwise the port
may burnout!
If RS-232 cable is used outdoors, please DO add a surge protector to protect the
equipment circuit!
It is strongly recommended to add a lightning arrestor on the RS-232 port to prevent
lightning damage.
Vent
The vent is designed to facilitate vapor and moisture egress out of the unit as well as to repel water,
dust and dirt by using the specially designed membrane, thereby preventing the SGT-LD-5-23 from
electric malfunctioning.
