UM-0909 5 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.

UM-0909 21 4.2 Starting Operation BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM. 1. Turn on the repeater, connect computer to repeater through USB cable, and run Fiplex Control Software. Check that all remote units are connected to the master through fiber optic checking link status. 2. Enable channel filtering if needed and setup desired channel frequencies. If Fiplex Digital Fiber DAS is 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. Link status
UM-0909 22 3. According to DL RF input levels, program input attenuator to avoid input overflow, and output attenuator for each remote to obtain desired output level in each remote. 4. Reciprocally, set UL band gain adjusting output attenuator of master unit. It is recommended that DL gain and UL gain be equal. Set number of active channels and frequenciesSet Input attenuatorSet Output attenuator
UM-0909 23 5. Set up squelch settings. Controls are independent in UL (for each remote) and DL (master) bands. Typical values for UL are between -110dBm and -100dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level received in any active channel minus 10dB. 6. Setup desired filter bandwidth, depending on presence of adjacent channels. In principle, recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal is detected, narrow filters can be used. Fine gain can be set to equalize input signals.
