61-83B-50-XXX-XX UserMan page 3 of 25 For Class A Unintentional Radiators This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
61-83B-50-XXX-XX UserMan page 4 of 25 Antenna System Installation The antenna or signal distribution system consists of two branches. An uplink branch typically uses an outdoor mounted, unidirectional gain antenna such as a yagi and a downlink signal radiating system consisting of a network of zero-gain whip antennas or lengths of radiating cable usually mounted inside of the structure. Even though the antenna system may not be supplied or installed by TX RX Systems.

61-83B-50-XXX-XX UserMan page 7 of 25 GENERAL DESCRIPTION Signal boosters extend radio coverage into areas where abrupt propagation losses prevent reliable communication. No frequency translation (conversion) occurs with this device. Signal Booster II (SB II) is a broadband, bi-directional signal booster available in a variety of configurations as shown in Table 1. The product model number is used to describe each configuration available.

SB II uses external heat sinks and needs to be mounted where there can be an unobstructed air flow over the heat sinks fins. The SB II cabinet will stay warm during normal operation so in the interest of equipment longevity, avoid locations that carr y hot exhaust air or are continually hot.

61-83B-50-XXX-XX UserMan page 10 of 25 AC Line Signal Booster II is designed to be hard-wired to 110 single phase AC lines at 50 - 60 Hz (see Figures 2 and 3). An AC line filter is provided for this purpose. There is a hole provided in the cabinet bottom-wall for bringing in the AC line. Fasten quick connect plugs to each wire of the incoming AC line, then connect the ground wire and hot wire to the respective pins on the top of the AC line filter assembly. Refer to the photo shown in figure 3.
61-83B-50-XXX-XX UserMan page 11 of 25 A six-terminal strip is provided for the interface and uses screw terminals for ease of connection. Route the alarm wires through one of the access holes in the bottom of the box, strip about 3/16” of insulation from each end, loosen the screw terminal, insert and retighten. Use #20 or #22 gauge insulated wire. Use of these terminals is optional. SB II also has a number of status LEDs built-in to individual modules to indicate a fault condition.

It is wise to repeat the procedure listed above for measuring antenna isolation with the signal generator set to frequencies at the passbands edges in order to see if the isolation is remaining relatively constant over the complete width of the passband.

This is the normal display for the signal booster. The system will return to this display from any other display if none of the menu interface buttons are pressed within 2 minutes. The exception is the OLC status display which does require a button press to exit.

Select Done using the arrow keys and press enter to return to the menu. Use the Cancel button to return to the Status Display. Detailed Status Screens These items allow a detailed examination of system components including; all amplifiers (current draw and temperature), the power supply (voltage level), and the OLC function (present status and historical archive).
61-83B-50-XXX-XX UserMan page 17 of 25 Alarms The system continuously monitors the current draw and operating temperature of each amplifier as well as the voltage level of the +12 and +24 VDC supplies. If any of these parameters exceed normal operating levels by a factory preset percentage the system enters an alarm condition. Notification of an alarm condition is provided by LED indicators and Form-C contacts available via the alarm terminal screws.
61-83B-50-XXX-XX UserMan page 18 of 25 tion of any alarm condition occurring and the second set of contacts indicate the system is operating on battery backup power. PERFORMANCE SURVEY It is a good idea to document the performance of the system after installation so that a reference exists for future comparisons. This information can make troubleshooting an interference problem or investigation of a complaint about system performance much easier.
61-83B-50-XXX-XX UserMan page 19 of 25 lightning strikes, failures may occur. The following procedures may be followed for detecting a malfunctioning unit or as part of a periodic maintenance program. 1) The heatsink area should be cleared of dust and debris. 2) Inspect the unit to see that the two power supply LED DC indicators are lit (remove any dust or debris that may obscure the LEDs). This will verify that DC power is flowing properly. Check all hardware for tightness.

The replacement amplifier comes with an attached gasket which must press up against the outside of the cabinet firmly and squarely in order to provide a correct moisture seal. Module Replacement The SB II modules are field replaceable. Follow the steps listed below in sequential order. The required tools are a #1 Phillips screwdriver.

The SB II low level and mid level amplifier stages are field replaceable by simply removing the module and plugging in a replacement. These modules are HOT switchable meaning they can be swapped without powering down the system. RF cables attached to the modules must be removed (5/16” wrench) prior to swapping the modules and must be re-attached after the new module is in place.
61-83B-50-XXX-XX UserMan page 22 of 25 2) Gently tilt only the top of the assembly up from the card cage. Keep the bottom of the assembly in place. The bottom mounting plate (part of the card cage) has an overhang on it to support the display/user interface board. If the assembly is lifted straight out the overhang it could possibly damage the interface circuit board. 3) With the display/user interface board standing up straight gently move it upwards while lifting it out about an inch or two.
