Product : LTE/CDMA(EVDO) Wireless Modem
Model name : LTD-VL2000
Copyright ⓒ. 2014. All Rights Reserved.
The LTD-VL2000 is achieved as personal mobile communication devices of
the compact radio equipment, the latest design of the parts becoming smaller,
lighter weight having the LTE(700/1700MHz), CDMA(850/1900MHz) bands. It is
the vehicle’s telematics system that connect with LTE and CDMA(EVDO)
wireless network and the wireless module with voice and data communication. It
can be operated at land, rivers, and other similar areas.
On LTE operating mode, It can be communicated with uplink 50Mbps, downlink
up to 100Mbps data transfer speed such as a movie or a video call. It may be
able to receive large amounts of data.
Standard RS-232 port and USB port communicating with the host system via
AT-command or control commands can be used to send data. Voice calls are
possible.

4. Electrical specification
4.1 Power supply specification
A Module Power supply(KL30) is delivered on DC 12V, 1.5A from host
system. In Module internal power supply, it is design for power management
integral circuits to distribute constant voltages, and can control the each
power block to minimize the power consumptions.
In particular, PAM(power amplifier module) has much power consumption so it
is supplied for directly 3.8V converted from KL30. Therefore it should be
careful to input the supply power of PAM when the absolute rating is over. In
addition, all of power input should be design with blocking and protecting high
surge and ESD in NAD module.

9. RFx Information
The RF field strength of the wireless module or modules that may be
embedded in your TCU is well all international RF exposure limits as known
at this time. Because the wireless modules(which may be embedded into your
TCU) emit less energy than is allowed in radio frequency safety standards and
recommendations, manufacturer believes these modules are safe for use.
Regardless of the power levels, care should be taken to minimize human
contact during normal operation. This module should be used more than 20cm(8
inches) from the body when wireless devices are on and transmitting.
This transmitter must not be collocated or operate in conjunction with any other
antenna or transmitter. Operation is subject to the following two conditions: (1)
this module may not cause interference , (2) this module must accept any
interference that may cause undesired operation.
10.1 Information for integrator
The integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user manual of the end
product. The user manual which is provided by integrators for end users must
include the following information in a prominent location. To comply with FCC RF
exposure compliance requirements, the antenna used for this transmitter must
be installed to provide a separation distance of at least 20cm from all persons
and must not be collocated or operating in conjunction with any other antenna or
transmitter. Label for end product must include contains FCC ID : YZP-VL2000
or A RF transmitter inside, FCC ID : YZP-VL2000

10. FCC Approval
This Module complies with parts 22, 24, 27 of the FCC rules.
This device complies with FCC radiation exposure limits set forth for an
uncontrolled environment.
This module should be installed and operated with minimum distance 20cm
between the radiating element of this device and the user.
This module may not be co-located with any other transmitters or antennas.
To comply with FCC regulations limiting both maximum RF output power and
human exposure to RF radiation, the maximum antenna gain including cable
loss in a mobile-only exposure condition must not exceed the table below.
Band Frequency Range
[MHz] Maximum Antenna
Gain[dBi]
CDMA(Cellular) 824.70~848.31
CDMA(PCS) 1851.25~1908.75
LTE(B13)
LTE(B4) 1710.70~1754.30
The satisfy FCC exterior labeling requirements, the following text must be placed
on the exterior of the end product.
Contains Transmitter module FCC ID: YZP-VL2000
Changes or modifications to this equipment may cause harmful interference
unless the modifications are expressly approved in the instruction manual. The
user could lose the authority to operate this equipment if an unauthorized
change or codification is made.
Note: If this module is intended for use in a portable device, additional testing
will be required to satisfy RF Exposure, including SAR requirements of FCC Part
2.1093.
