
Nominal passband gain: 80dB max
Nominal bandwidth: 18MHz maximum for Canada market
Rated mean output power: Up to +37dBm maximum.
Input and Output impedances: 50 ohms
The Manufacturer's rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by 3.5
dB, especially where the output signal is re-radiated and can cause interference to adjacent band
users. This power reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device.

2. Product Description.
The Fiplex PS800 Digital DAS has a modular structure that consists on two different modules, the Digital Master
Unit DHS00-M and the Digital Remote Unit DHS37-R. Each one of the different modules is enclosed in the same
or equivalent case, therefore, product description and installing instruction sections are valid for all of them.
The Fiplex Digital Master is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are done using
FPGA based Digital Signal Processing. It provides a connection to the Base Station and it centralises all the
connectivity of the DAS. It also provides the possibility to connect up to six Digital Remote Units.
The Digital Remote Unit, also is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are also
made using FPGA based Digital Signal Processing. It provides amplification to the RF signals needed to provide
signal amplification into the target area.
The Master and Remote Units is where the RF interfaces are located, the Master Unit has the “To Base” interface,
and the Remote Unit has the “To Mobile” interface. The Master and Remote Units have internal duplexers
therefore, the RF interface will have one RF port in each unit, the Master will have a “To Base” RF Port, and the
Remote Units will have “To Mobile” RF Ports.
The advantages of using digital signal transportation over fiber are to avoid the addition of the fiber analog noise
when it is used to transport analog signals. Along with this, the UL squelch of the Digital Remote Unit works not
only per channel but also per time slot, this makes the Fiplex Digital DAS solution unique by its outstanding
management of the UL noise.
The Fiplex Digital Master Unit can be fed with a number of Base Stations or Off the Air. The direct connection to
a base station is done though the Point Of Interconnection (POI) and depending on the configuration and amount
of Base Stations it can be something simple as a directional coupler and a duplexer or something more complex
that can consist on several directional couplers, splitters, duplexers.
The Fiplex Digital Master Unit also provides an access point to monitor and control all the system parameters
not only of the Digital Master Unit but also to each Digital Remote Unit connected on the system. This connection
can be done locally via USB or Web-Browser, or remotely using Ethernet (via SNMP protocol).
The DHS00-M and DHS37-R are NFPA Ready orderable with AC or DC option. As optional it can have remote
control via Ethernet or via wireless modem.
The Digital Master Unit and the Digital Remote Units both have heavy duty IP67/NEMA4X cabinet for outdoor
usage, it is designed to be wall or pole mounted, however, to mount on standard 19” rack, a special mounting kit
can be supplied.
For more details refer to the product datasheet.

independently adjusted (if filtering is enabled)
If filtering is enabled, gain of each channel can
be fine adjusted
Level of each channel, measured according to
its bandwidth filter, is shown in dBm units. Led
indicator shows if levels exceeds squelch
threshold (green) or not (yellow).
Show gain reduction to prevent overloading in
AGC per channel
Enabling this control, repeater does not transmit
in each channel if RF input power do not exceed
the threshold level configured according to next
row
If squelch is enabled, input levels below this
threshold are not transmitted.

6.3 Software description (Remote Unit)
While software connected to digital master allows configuration and monitoring of whole system, if
software is connected to remote unit, only parameters of this unit can be viewed / modified.
Then, status screen of remote unit only shows information regarding this unit:

Distribution and meaning of the controls contained in status page are very similar to single remote
frame of master status page, only optical frame is different due to only remote side of optical link is
monitored.
Local Software. Installation and troubleshooting
7.1 Installation
The following section will describe the steps to be followed in order to install and use the Fiplex
Control software with your Fiplex repeater.
1. Before connect USB cable between computer and repeater, run the
FiplexControlSoftware.msi File. Next screen will appear…

5. Connect USB cable between computer and repeater, keeping the repeater powered off.
Usually, drivers will be automatically installed, but depending on Windows version, screen
asking for drivers of new device can appear. Drivers can be found in application folder:
C:\Program Files (x86)\FiplexControlSoftware\drivers”.
6. Turn on the Repeater
BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY
LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM.
7. Execute the Fiplex Control Software. Next window will appear:

User interface has the following controls:
Scan Devices Button: refresh the available COM ports and identify Fiplex devices
Connection Button: connect / disconnect software from repeater
List of available devices: below two buttons, is placed a dropdown list that shows all
available COM ports. Available COM ports not related to Fiplex devices will be shown
with its number and “Unknown device” label. COM ports related to Fiplex devices will
show a device description.
Embedded Web browser: graphical area where configuration and monitoring parameters
will be shown.
File menu: contains menus to save repeater configuration to a file and load configuration
from file to repeater.
NOTE: if Fiplex Repeater is not turned on, related COM port will appear as “Unknown
device”
8. Click “Scan Devices”
UM-0909
38
Now, the Fiplex unit is shown in the list of available devices, and connection button is
enabled.
NOTE: Fiplex repeater could not appear in list, if COM port number is higher than
COM16, depending on Windows version. COM port number can be forced to arbitrary
number (below COM16) through Device Administrator. In order to change COM number,
click “Properties” pop-up menu:
Click “Advanced Options”
