1. Safety and other precautions
1.1. General
IMPORTANT: FOR THE EFFICIENT AND SAFE OPERATION OF YOUR CROSSLINK TG, READ
THE INFORMATION BELOW BEFORE USE.
Care must be taken when handling the unit. It should not be dropped or exposed to excessive heat.
Only authorized staff can disassemble the product. In the case that the product was disassembled
by un-authorized personnel, the warranty will be void.
Do not push foreign objects into the openings of your device. Doing so can cause fire or electric
shock by shorting out interior components.
The product can withstand harsh conditions. But if the product is exposed to severe conditions
beyond the limits specified in Environmental Specifications, the product could be damaged.
Keep the device away from radiators and extreme heat sources. Do not use the CrossLink TG
submerged in wet or very humid environments.
The device may become hot during normal operation, to avoid burns, switch it off and wait for it to
cool before handling it.
Do not clean the device when it is powered. Clean it with a soft cloth. Do not use liquid or aerosol
cleaners, which may contain flammable substances.
1.2. CrossLink TG connections
The highest internal voltage applied to the CrossLink TG unit can be 48Vdc and complies with the
low voltage European directive.
The power supply can be made with a battery or continuous voltage supply with reinforced
isolation, and limited in power to a maximum of 8A and 100VA.
Before you connect the device to a power supply, check the voltage and current rating to ensure that
the required current range matches the available power source. Exceeding the specified input range
may cause unexpected operation and/or irreversible damage to the CrossLink TG.
When you wish to remove the device from all power sources it is advisable to first turn the device
off and then disconnect it from the power supply.
For added safety be sure that nothing rests on the connected cables and that the cables are not
located where they can be tripped over or stepped on.
Applying loads outside of the range specified may result in unintended operation and/or possible
permanent damage to the CrossLink TG. If there is any uncertainty, please visit
https://support.crosscontrol.com/
1.3. EMC Instructions
Use shielded signal cables to ensure that you maintain the appropriate EMC classification for the
intended environment.
Keep cables as short as possible for your application, ideally not longer than 3 meters.

1.4. Exposure to RF Energy
Minimize RF energy exposure by limiting the duration of GSM calls and operating the unit in an
efficient manner.
The antenna must be mounted in such a position that no part of the human body rests close to any
part of the antenna. The product is intended to be used with an external GSM antenna, located at
least 20 cm away from any part of the human body. Those installations not complying with this
statement are responsible for providing SAR measurement reports and a corresponding
declaration.
Do not hold the antenna during a call since it affects call quality and may cause the module to
operate at a higher power level than is normally required.
1.5. Antenna care and replacement
Do not use the product with a damaged antenna because an exposed antenna can come into contact
with skin, and a minor burn may result. Therefore, replace the antenna immediately.
Use only antennas that are rated in accordance with the technical specifications. Antennas that do
not fulfil the specifications could damage the product and may contravene local RF emission
regulations or invalidate system approval.
1.6. Electronic devices
Most electronic devices are shielded from RF energy. However RF energy may cause some
malfunctioning of improperly shielded electronic devices.
When the product is mounted in a vehicle, check your vehicle to determine that all on board
electronic equipment is adequately shielded from radio waves.
In the same way, when the product is in the proximity of medical devices (such as in hospitals, etc.)
check with the manufacturer of medical equipment to determine if they are properly shielded.
This equipment should never be operated on an aircraft.
1.7. Blasting areas
To avoid interfering with blasting operations, turn the unit OFF in these situations or in areas
ordered to “turn off your two way radio”.
Similarly construction crew often uses remote control RF devices to set off explosives so proper
care should be taken in proximity to these areas as well.
1.8. Children
Do not allow children to play with CrossLink TG. It is not a toy and they could hurt themselves or
others. Children could also damage the unit.
1.9. Explosive atmospheres
Do not operate this product in environments containing explosive materials or vapour. This
includes petrol vapour at service stations.
The unit accessories could generate sparks that can cause an explosion or fire resulting in bodily
injury or even death.

To avoid interfering with blasting operations, turn the unit off in areas posted as such.
Do not transport or store flammable gas, liquid or explosives, in the compartment of your vehicle
which contains the CrossLink TG or its accessories.
1.10. Handling the device
Observe the following safe-handling guidelines to prevent damage to CrossLink TG:
When setting up the device for work, place it on a flat level surface.
Protect the device from environmental hazards such as dirt, dust, food, liquids,
temperature extremes, and overexposure to sunlight.
When you move your device between environments with very different temperature and/or
humidity ranges, condensation may form on or within the device. To avoid damaging it,
allow sufficient time for the moisture to evaporate before using the device.
When taking the device from low-temperature conditions into a warmer environment or
from high-temperature conditions into a cooler environment, allow the device to acclimate
to room temperature before turning on power.
When disconnecting a cable, pull on its connector or on its strain-relief loop, not on the
cable itself. As you pull out the connector, keep it evenly aligned to avoid bending any
connector pins. Also, before you connect a cable make sure both connectors are correctly
oriented and aligned.
1.11. CrossLink TG with Battery
Some models include the optional lithium-ion battery backup. Do not dispose of the battery along
with household waste. Contact your local waste disposal agency for the address of the nearest
battery disposal site.
The battery poses a burn hazard if handled improperly. Do not disassemble or handle a damaged
battery. If the battery is damaged, electrolytes may leak and can cause personal injury.
Keep the battery away from children.
When the battery is heated to excessive temperatures, its cells could explode, posing a risk of fire.

3. Getting Started with the UDK
This section explains the steps to install and configure the UDK development kit to begin the set-up
of the customer applications.
3.1. Layout
The standard unit has GSM and GNSS external antenna connectors, while Bluetooth and Wi-Fi
antennas are internal, as shown in the following image.
When using either Wi-Fi or Bluetooth functionality, try to make sure that the installation exposes
this side of the unit. The “UP” mark shows the side that should be exposeed, and the front should
also not be in direct contact with metallic surfaces.
