FCC Compliance
This is a 90.219 Class B device.
WARNING: This is a 90.219 Class B device. This is NOT a CONSUMER device. It is designed
for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC
LICENSE or express consent of an FCC Licensee to operate this device. You MUST register
Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signalboosters/registration. Unauthorized use may result in significant forfeiture penalties, including
penalties in excess of $100,000 for each continuing violation. The installation procedure must
result in the signal booster complying with FCC requirements 90.219(d). In order to meet FCC
requirements 90.219(d), it may be necessary for the installer to reduce the UL and/or DL output
power for certain installations.
ATTENTION: This device complies with Part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
ATTENTION: FCC regulation mandate that the ERP of type B devices should not
exceed 5W (+37dBm). This device has a maximum programmable composite output
power of 5W (+37dBm), therefore this unit should always have its output attenuated
by 0dB, including cable loss, splitter loss, directional coupler loss, all passive elements
loss and also antenna gain. The loss in cables and passive devices connected to the
output of the device and the gain of the DL antenna should be of 0dBi or less and maintain a
minimum separation of 35 cm from all persons

2. Product Description.
The DH437-R is an FPGA based Digital Fiber Optic Remote Unit that transmit in the Downlink frequencies of
470-488MHz and receives in the Uplink frequencies 470-488MHz for United States.
This Remote Unit extends the radio coverage into areas inside the Base Station range where propagation losses
prevent reliable communication.
The DH437-R is fed by fiber via a Digital Master, the DH400-M. The DH400-M is connected directly to the B|ase
Station with no radiating elements.
The Master Unit provides the wired interface to the Base Station.
The DH437-R Remote Unit is the device where the service antennas are connected. Each DH437-R has dual
hardware, so it works as two identical and independent Remote Units integrated into one box. Each DH437-R
has two DL outputs and two UL inputs one per each internal Remote Unit.
The physical connection between the Master Unit and the Remote Unit is SM Fiber Optic cord. Each Remote
unit inside the DH437-R uses a separate fiber.
The Master Unit receives the DL input signal from a direct connection of Base Station, after that, it is sent though
a digital link to the Remote Unit. The Remote Unit the data is converted back to RF, amplified and radiated to
the Service antennas.
At the Uplink Input port, the Remote Unit receives the UL signal. The UL input signal comes from the Service
antennas, after that, this signal is digitally converted from RF to optical signal, and sent over the fiber. This signal
in the FO cord is captured by the Master Unit, re-converted from Optical to RF and sent back to the Base Station
though a direct connection.
The optical link allows the system to cover places which are far away from Base Station with fewer losses.
This DAS System is capable of handling 24 filters in uplink and 24 filters in downlink. The center frequency of
each one of the 24 filters can be tuned via a software interface.
The intermediate filtering of this equipment is performed by using FPGA based Digital Signal Processing that,
among many, has the following features:
- High Selectivity vs Low Delay performance selection.
- AGC per channel and per time slot.
- Squelch per channel and per time slot.
- Integrated Spectrum Analyzer.
Both Master Units and Remotes has the same a heavy duty IP67/NEMA4X cabinet for outdoor usage, it is
designed to be wall or pole mounted..

Installation
Mounting the cabinet
Fiplex Digital DAS is designed for outdoor usage with a weather proof outdoor NEMA4 cabinet that can be
mounted without any kind of shelter from rain, snow or hail.
However, to improve reliability, it is recommended to mount the Digital DAS on a site with shelter from direct
exposure to sun, rain, snow and hailing.
It is not recommended to operate the DAS under bad weather conditions, such as:
- Intense rainfall, snowfall or hail
- Storm or high wind
- Extremely low or high temperature
- High humidity of the air
Mounting
1. Mount the bracket
The cabinet can be mounted on a wall or pole. These mounting cases are shown below in Figure 1 and
Figure 2. The bracket is provided with each cabinet.

Use of Liquid Tight Conduit
The unit has available a Liquid Tight Conduit Fitting connector. The unit as standard has the
connector installed, so if the user requires to use this connector, if available, the NFPA cables,
Ethernet, DC and AC cables can be routed through this connector.
Figure 9; AC Routing through cable gland or conduit connector
If the is not going to use Liquid Tight Conduits, then the connector should be replaced by the
provided sealing cup as indicated in Figure 10.

Nema4X considerations
This device is equipped with a Nema4X enclosure, however, to ensure the Nema rating,
the user must have the following considerations:
1. Correct use of the Liquid Tight Conduit. In case this interface is not used, it should
be replaced with the sealing cup.
2. Sealing cups should be installed in the non-used cable glands.
3. The RF Ports should be perfectly mated.

used as channel selective, user has to know what frequencies are used in base station. Each channel
can be enabled independently. Channels not used can be showed / hidden using the “Show channels”
checkboxes. If remote units are on and connected through optical fiber, the corresponding uplink
frequencies will be automatically set, too.

Part 2 SOFTWARE
Introduction
Fiplex Fiber DAS can be fully configured and monitored through USB connection. Digital Master
unit receives through optical links monitoring and configuration data from remotes units. For this
reason, whole system can be fully configured and supervised from digital master unit.
USB Software
6.1 Software description (Digital Master)
If software has been successfully installed and connected to Digital Master (see section 7) status
screen will appear. In this screen, RF configurations parameters (channel frequencies,
bandwidth filter, gains / attenuation) and RF and optical links monitoring (RF input/output levels,
AGC status, optical link status) are shown.
At left side of webpage, configuration menus are shown:
 Content
DH437-R

Status: whole RF configuration and monitoring parameters are shown. These
parameters are described in next section.

Tag: user can set a tag to ease repeater identification. For modifying the TAG, write
a new value in text field and click over Apply Changes link
26
DH437-R

IP: At this page (for units with Ethernet supervision), IP addresses configuration and
addresses of SNMP Managers are shown. User can set addresses of two SNMP
Managers (IP where SNMP agent will send TRAP information). To modify, click over
Apply Changes link after writing new values on text fields. Also router 3G IP address
can be viewed in this screen (if 3G router option is installed)

Downlink Spectrum: in order to know input signal: level of desired channels,
unwanted channel levels, Digital Master provides an spectrum analyzer that shows
input signal in frequency domain.

Date & Time (for units with Ethernet supervision): page to modify real time clock.
When the repeater is not powered, this clock runs with a voltage supply provided by
27
a 3V lithium battery, button type of 20mm (CR2032) with 220mA·h. This suffices for
at least half year. When the repeater is powered, no current is drained from the
battery. So, actual battery life will depend on repeater usage. For battery
replacement, please locate battery holder between USB and Ethernet connectors on
main board. Battery positive side is UP, i.e. on holder clip.
After clicking on “Apply Changes” link, next message will appear, warning the user that
system needs to be rebooted.

Configuration
o Apply Changes: as it is said above, this link is used to load changes to the
repeater, in configuration, tag, IP, password and date and time menus. After
any configuration change, web page will show and icon that allows user to
know if configuration has been successfully applied:
