After amplification, the signal is passed through to the indoorantennas. Conversely, signals from handsets are amplified and retransmitted to thebase station.
ACE Technology52. Installation2.1 IntroductionThis section provides information for the installation and setup of the USR-1900repeater. The information consists of procedures for unpacking, inspection andpreparation for the installation, as well as the actual installation and the setup.2.2 Unpacking and InspectionExamine the shipping carton for damage before unpacking the unit. If the shippingcarton is damaged, try to have the carrier’s agent present when the equipment isunpacked. If visual inspection reveals physical damage(s) to the equipment, youshould send it back for replacement.Verify that the equipment is complete, as listed under packing slip. Contact ACETechnology with any missing component.2.3 Preparation for Use2.3.1 Power RequirementsThe power supply of the USR-1900 accepts 110 VAC, at 50 ~ 60 Hz. Powerconsumption of the USR-1900 is approximately 16 Watts.2.3.2 Operating EnvironmentThe USR-1900 is intended for indoor use only. Do not install it where it might beexposed to the outside elements as this could result in destruction of the unit andother hazards.For normal operations, the environmental conditions should be as follow:Temperature range: –10 °C to 45 °C, Maximum Humidity: 95 %Professional Installation OnlyAlthough the installation of the repeater unit is simple and straightforward, the transmissionlines for both external and internal antennas require professional installation by a licensedcommunication technician. In addition, the installation must conform to all applicablefederal, state and local government regulations.
ACE Technology62.4 Before InstallationYou will need to determine the following before beginning the USR-1900installation:a. Base station locationb. Location where the outdoor antenna is to be installedc. Location where the indoor antenna is to be installedd. Location where the USR-1900 is to be installede. Length and type of coaxial cable needed to connect from the outdoor antenna tothe repeater unitf. Length and type of coaxial cable needed to connect from the repeater unit to theindoor antenna2.5 Antenna Installation2.5.1 Outdoor AntennaSelect a site for your outdoor antenna, making sure you have enough signal strengthat that location. Using coax cable, connect the antenna to the repeater. If you areusing a directional antenna such as a Yagi type, the antenna should be installed sothat it is in line of sight of the base station. Then, align the directional antennatoward that direction, and secure the antenna using provided mounting hardware.Use of a lightning arrester is highly recommended. By installing a lightningarrester between the outside antenna and the repeater, you can protect the repeaterunit from electrical surge from lightning.CAUTION: In order to comply with FCC rules for RF exposure, thefollowing must be observed:The antenna must be installed such that a minimum separation distanceof 20 cm is maintained between the antenna and any persons.
ACE Technology72.5.2 Indoor AntennaInstall the indoor antenna at a convenient location. It should be free of metallicobstruction in order to have an effective coverage. Depending on the circumstanceof the installation, either one or a combination of following antennas can be used:Ceiling mount patch antenna, Wall mount patch antenna, Corner reflector2.6 Repeater InstallationUSR-1900 is an indoor repeater. Accordingly, the environment of the intendedinstallation site needs to be considered. The repeater must be shielded frommoisture, such as rain, and excessive temperatures. The operating temperaturesshould be between -10 °C and 45 °C.2.6.1 Turn-On ProcedureVerify all RF connectors are tightened and cables and antennas are secured. On therepeater, switch “ON/OFF” to ON position. The Power indicator LED should begreen. Make sure that no other LED is illuminated. If any other LED is lit, consultthe trouble shooting page of this manual, or “2.6.2 Antenna Isolation andAlignment” section.2.6.2 Antenna Isolation and AlignmentUSR-1900 is equipped with an over drive protection circuit. If the circuit detectsthat the repeater is transmitting at a power level above that allowed by the FCC, itshuts down the repeater and the appropriate overdrive LED will start to blink. Inthe event that this condition persists for more than 3 minutes, the repeater will shutitself down and needs to be reset, by turning the AC power switch off and on, toresume operation.
ACE Technology8A. Antenna IsolationIf the isolation between the outdoor and indoor antennas is not sufficient, the repeaterwill oscillate and turn itself off. It is recommended that when turning on the repeaterfor the first time, both the up link and down link attenuation, marked “UPLINKATT.” and “DOWNLINK ATT.” respectively, should be fully engaged. Thedipswitch setting and the levels of attenuation are shown in figure 2-6 and Table 2-6.<Figure 2-6: Dipswitch setting><Table 2-6: Dipswitch Setting>Dipswitch Number 1234Attenuation (dB), (Dipswitch ON) 2 4 8 16As shown in table 2-6, each dipswitch has different attenuation associated with it,and may be used in combination of others. For example, to obtain an attenuation of20 dB, dipswitches number 2 and 4 should be in “ON” position, and the dipswitchesnumber 1 and 3 should be in “OFF” position. (0 + 4 + 0 + 16 = 20). Attenuationlevel can be set from 0 to 30 dB by 2 db increments.Starting from the maximum attenuation, 30 dB, decrease the attenuation level in2 dB steps by manipulating the dipswitches until all the switches are in “OFF”position, or stop and back off by 2 dB if you trigger either of the over-drive alarms,“OVRPWR ALM”, for maximum gain.B. Antenna AlignmentIf you are triggering the overdrive alarms at any point, try to increase the isolationbetween the antennas by relocating them. The indoor antenna should be placedphysically as far away from the outdoor antenna as practical. If the geometry of theintended coverage area allows it, you should also try the indoor antenna in suchway that interference between the antennas is at the minimum. If you are usingdirectional antennas, try to find a location for the indoor antenna where it can coverthe needed area and oriented back to back with respect to the outdoor antenna.NO1 2 3 4 OFFON

ACE Technology113. Operation3.1 IntroductionThis section provides information for operating the USR-1900 repeater.3.2 Operating Instruction3.2.1 Power-upConnect the repeater to AC power supply using the provided power cable. Push the“SWITCH” to “ON” position. The red LED on the switch should light up. All fiveLEDs will blink momentarily while the unit goes through initialization, whichincludes checking the alarm status. If no alarm condition is present, only the“POWER” LED will remain lit. The repeater is then operating properly.3.2.2 Alarm Status3.2.2.1 Overdrive AlarmThere are two overdrive alarms on the unit, one for the down link marked“DWNLNK OVRP ALM”, and another for the up link marked “UPLNK OVRPALM”. Over driving occurs when the RF output power of the repeater exceeds aprescribed limit. This means that the input RF power level is too high, or therepeater is oscillating. The condition may be transient, caused by a passingemergency vehicle emitting a strong signal for example, or permanent, due to anearby base station. It may also indicate low isolation between the antennas, whichcauses the unit to oscillate (please refer to the section 2.6.2 of this manual forantenna alignment and isolation.)The overdrive alarms on the USR-1900 repeater are design to detect whether the overdriving is transient or permanent. When overdriving is detected, power to the RFpower is cut off and the LED flashes. After approximately 1 minute, the unit will testto see if the condition persists. If it does not detect overdrive the unit will power up andcontinue to operate. If it still detects overdrive, it will wait another minute. If it detectsoverdrive for the third time, it will shutdown the unit completely. Once the shutdownis triggered the system needs to be re-initialized by turning the AC power off and on inorder for the repeater to function.
ACE Technology123.2.2.2 PLL Unlock AlarmThere are two PLL unlock alarms on the unit, one for the down link marked “DWNPLLALM” and another for the up link marked “UP PLLALM”. These alarms aretriggered when the PLLs, critical components of the repeater, fail to functionproperly. The unit will not operate while either one of the alarms is on. Turn offthe power and call for service. This malfunction is both critical and permanent.The unit needs to be replaced.3.2.2.3 Power AlarmThe AC power indicator, marked “POWER” doubles as the power alarm. Itmonitors the function of the power supply. If the power supply malfunctions, or theAC input voltage is out of range (85 – 132 VAC), it will cut off the power to the RFpart of the repeater. However, power to the controller is still available to keep thealarm on, which is indicated by flashing POWER LED. If the AC power supply isdetermined to be within the range and the power alarm is still on, then power downthe unit and call for service.4. Trouble ShootingIf the repeater does not operate properly after installation, first make sure that theinstallation procedures as described in section 2 of this manual were followedcorrectly. Inspect each connection, both RF and AC, and connectors for a securefit, checking to see if all the connections are made to the proper ports of the unit andthe antennas.If the malfunction is due to an alarm condition, refer to the appropriate part of thesection 3.2 of this manual. Corrective actions may be taken for the overdrivealarms. However, if the PLL unlock alarms or the Power alarm is (are) on, the unitneeds to be repaired by a factory-authorized technician.There are no user serviceable parts in the USR-1900.DO NOT OPEN the unit. There is a danger of an electricshock. Opening the covers of the unit will void all warranties.CAUTION!
