Product Description Cellular Specialties, Inc. (CSI) developed this Bi-Directional Amplifier (BDA) for use where sufficient signal from local repeater sites to operate public safety communications devises was unavailable within the building. It is necessary that sufficient signal be available on the roof of the structure. The BDA is connected to an external antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where communications service is desired.

Installation Example: Typical Single Internal Antenna System Design Outdoor Donor Antenna Antenna located on roof of building and grounded in accordance with NEC 810-15, 21. Align antenna with donor site to achieve highest signal strength reading Lightning arrester located at building penetration point and grounded. CSI-T61080-10W-SP78 or CSI-T61080-10W-WSP78 Bi-Directional Amplifier Indoor Server Antenna Optional Accessories A complete line of accessories is available from Cellular Specialties, Inc.
Important Installation Notes • A high degree of isolation must be afforded to prevent any re-generative feedBack in the system. FeedBack of this nature causes the amplifier to emit a continuous signal of maximum amplitude and could, in some cases, interfere with normal operation of the donor site. The use of window mounts or other non-rooftop mountings antennas should be avoided.

The View Menu Series View Menu Tree Screen Saver any key Page 8 MENU Power Readings Page 8 MENU Oscillation Events Page 9 MENU Overheat Events Page 9 This series of menus will allow the user to view, but not alter, the information stored in the BDA. Pressing the EDIT button will cause the BDA to ask for a password, if password control is invoked. Password control is invoked by pressing EDIT and MENU simultaneously.
Screen Saver Display Upon powering up the BDA, a display resembling this will appear on the LCD panel: The first row contains the network name of the BDA; this allows the user to determine which BDA they are looking at. This name can be changed to whatever the user desires, and can contain blank spaces, capital letters, lowercase letters, and numerals. It is limited to seven characters to facilitate communication with a Web Monitor, should one be desired.
Event Readout Displays Three performance measures are tracked within the BDA, and are recorded and displayed as events. Up to 999 of each type of event is recorded. If more than this number of events are detected, the menu system will continue to display the maximum number of 999. A typical display might look like this: Three types of service affecting events that the BDA records can be viewed within separate windows. Pressing the MENU button will sequence through these displays.
• Over Temperature Limit: Amplifier junction temperature is monitored continuously. If the temperature rises above a factory determined limit, an Overheat Event will be recorded. If the event is transitory, each excursion above the limit will increment the Overheat counter. A yellow LED will remain illuminated until the counter is reset to zero. Event counters serve as diagnostic tools for maintenance and system health assessments. Only isolation control will alter the intended performance of the system.
BDA Name and Address Display In addition to its name, a BDA can be uniquely identified on a network with a Web Monitor by its name. The name here is identical to the one in the Screen Saver Display. The BDA name is limited to seven characters. Each BDA accesible by a single Web Monitor on the network must have a unique address within that network between one and seven, inclusive. This display also shows the current BDA’s network address.

Edit Events Display These displays will show you the number of events recorded two categories (Oscillation and Overheat). Each MENU button press will move to the next display. At any event category, pressing EDIT will clear the counter and rest the number of events to zero. To indicate that you are currently in the EDIT series, the first word in the top line of the display will always be EDIT followed by the name of the display. A typical EDIT EVENTS display might resemble the following: .
A typical downlink EDIT Display may look like this: The MENU button will take the user to the Edit Uplink Gain display. Edit Uplink Gain Display This display is functionally identical to the Edit Downlink Gain display, but alters the gain through the uplink pass band instead of the downlink pass band. A typical uplink EDIT Display may look like this: Pressing the MENU key here will take the user to the Edit BDA Name display.
Example: In the above display the cursor shows that the user is at the fourth character position. In the below display the user has used the UP and DOWN buttons to select “S”.
When the BDA operation mode is returned to NORMAL, the FAULT LED will extinguish. Pressing the MENU button at this point will cause the BDA to display the Create New Password display. Create New Password Display This display will allow the user to enter a new password. The display, however, will not be viewable until password control is invoked by first pressing the proper keys simultaneously (SAVE and MENU).
BDA returns to the Screen Saver display. If the BDA does not detect any key presses within ten minutes of the last key press, the BDA will discard all changes made in the Edit Menu series since the last password entry and revert to the Screen Saver display. Final Note: If the BDA should become unstable, and none of these menu commands are operable, the processor can be reset to factory defaults by pressing and holding the UP, DOWN, and MENU buttons simultaneously for one second.
Troubleshooting All cables should be carefully checked for “shorts” and “opens”. The rooftop antenna, if directional, should be checked for proper alignment along the calculated compass heading. Typically, the directional antenna should be aimed at the same site that your handset uses in the area where the outside antenna is placed. If cables and alignment are acceptable, it may be necessary to use a spectrum analyzer to examine the signal environment in which the BDA is operating.
