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.

Technical Manual 2019-03-19

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.

CrossLink TG Product revision: 1.0

Technical Manual 2019-03-19

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.
