Wide Screen Overhead Monitors 3
Overview Brunswick Wide Screen overhead monitor packages come in three configurations; Brunswick supplied LCD Wide Screen monitors, bowling center supplied off-the-shelf Wide Screen monitors, and bowling center supplied offthe-shelf SCART Wide Screen monitors (Europe). When Brunswick supplies the LCD monitors, the center is able to turn the monitors on/off and switch the scoring monitor between the scoresheet and TV video through either the control desk or by using the remote control that comes with the monitors. A TV-Only monitor is also an option. These commercial quality monitors connect to the scoring system through a Wide Screen Overhead Interface. The Scoresheet monitor used a Model BI interface while the TV Only monitor uses the Model TVO interface. If a bowling center supplies their own Wide Screen monitors, the Brunswick scoring system converts the signal from the Scoring Computer so that it can be displayed on the monitors. On/Off control and video switching between the scoresheet and TV video must be done from the remote control that comes with the monitor. In addition, the bowling center is responsible for running any TV signal to the monitors. This type of monitor connects to the scoring system using the Wide Screen Overhead Interface - Model CI. For European installations a bowling center supplied monitor with a SCART interface can be used. On/Off control of these monitors (from the front desk) may be available if the monitor responds to the 12V signal on the SCART connector. Otherwise the remote control that was supplied with the monitor must be used to control the power. Switching between the scoresheet and TV video is done through the remote control that comes with the monitor. The bowling center is responsible for running their own TV signal to the monitor. This type of installation is directly connected to the scoring system and does not require the use of a Wide Screen Overhead Interface.
4 Wide Screen Overhead Monitors
Wide Screen Overhead Interface - Model BI and Model TVO The Wide Screen Overhead Interface comes in three versions or models; BI, CI, and TVO. For Brunswick Installed LCD monitors models BI and TVO are used. Model BI is used for the Scoresheet monitors and can adapt both scoresheet and TV video signals and provides desk control to turn the monitor on/off and switch between the TV and Scoresheet video. Model TVO is used for the TV-Only monitors. It allows for the display of the TV video and control of the monitor power. It does not provide the scoresheet video signal.

Sync Separator Board (SSB) The Sync Separator Board (SSB) adapts the scoresheet video signal so that it can be used by the Wide Screen monitor. The board adapts the video signal in two ways. First, the video signal goes through an amplifier which creates a common ground for the four signals (RGBS) and keeps the signal level of each at a level that the display can use. Second, the sync signal which is made up of both vertical and horizontal signals (composite sync) is altered so that horizontal and vertical are separated and supplied to the display through own wires. Refer to figure titled Sync Separator Board (SSB).

Serial Communication Controller (SSC) The Serial Communication Controller (SSC) allows a scorer computer to "communication" with the monitors so that video selection (TV or Scoresheet) and on/off can be controlled from the desk rather than the hand held remote control that came with the monitor. The boards are daisy-chained together from an RS-232 Converter attached to COM1 of a scorer computer allowing a scoring computer control 8 lanes of scoresheet monitors and 4 TV-only monitors. Dipswitches on the board are used to set an unique ID for each SCC and to determine whether the board will be used for scoresheet and TV or just TV. Refer to the figure titled Serial Communication Controller (SCC).

Maintenance of Brunswick Installed Wide Screens Although the monitors require very little maintenance it is suggested that you follow the following recommendations to keep them running at optimum performance.
Cleaning General Cleaning Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner.
Vent Holes Keep the vent holes on the back of the LCD clean of dirt and dust. It is recommended to wipe holes with a soft cloth a minimum of once per year. If using the internal cooling fan continuously, it’s recommended to wipe vent holes a minimum of once a month.
Adjustments Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability. Refer to the monitor vendor manual for specific adjustment procedures.
Maintenance of Bowling Center Supplied Wide Screen Overheads As each manufacturer has their own maintenance requirements, it is impossible to give specific recommendations for monitors supplied by a bowling center. As such it is important to follow the manufacturer's recommendations for your monitors. In general, it is important to make sure that any vent holes are clear of obstructions and the monitors is adjusted and cleaned for optimum readability. Always check with the manufacturer of your monitor before using any cleaning solution or glass cleaner.

Wide Screen Overhead Monitors 3
Overview Brunswick Wide Screen overhead monitor packages come in three configurations; Brunswick supplied LCD Wide Screen monitors, bowling center supplied off-the-shelf Wide Screen monitors, and bowling center supplied offthe-shelf SCART Wide Screen monitors (Europe). When Brunswick supplies the LCD monitors, the center is able to turn the monitors on/off and switch the scoring monitor between the scoresheet and TV video through either the control desk or by using the remote control that comes with the monitors. A TV-Only monitor is also an option. These commercial quality monitors connect to the scoring system through a Wide Screen Overhead Interface. The Scoresheet monitor used a Model BI interface while the TV Only monitor uses the Model TVO interface. If a bowling center supplies their own Wide Screen monitors, the Brunswick scoring system converts the signal from the Scoring Computer so that it can be displayed on the monitors. On/Off control and video switching between the scoresheet and TV video must be done from the remote control that comes with the monitor. In addition, the bowling center is responsible for running any TV signal to the monitors. This type of monitor connects to the scoring system using the Wide Screen Overhead Interface - Model CI. For European installations a bowling center supplied monitor with a SCART interface can be used. On/Off control of these monitors (from the front desk) may be available if the monitor responds to the 12V signal on the SCART connector. Otherwise the remote control that was supplied with the monitor must be used to control the power. Switching between the scoresheet and TV video is done through the remote control that comes with the monitor. The bowling center is responsible for running their own TV signal to the monitor. This type of installation is directly connected to the scoring system and does not require the use of a Wide Screen Overhead Interface.
4 Wide Screen Overhead Monitors
Wide Screen Overhead Interface - Model BI and Model TVO The Wide Screen Overhead Interface comes in three versions or models; BI, CI, and TVO. For Brunswick Installed LCD monitors models BI and TVO are used. Model BI is used for the Scoresheet monitors and can adapt both scoresheet and TV video signals and provides desk control to turn the monitor on/off and switch between the TV and Scoresheet video. Model TVO is used for the TV-Only monitors. It allows for the display of the TV video and control of the monitor power. It does not provide the scoresheet video signal. Refer to the figures titled Wide Screen Overhead Interface Model BI and Wide Screen Overhead Interface - Model TVO. (3) COMPOSITE VIDEO TO LCD

Sync Separator Board (SSB) The Sync Separator Board (SSB) adapts the scoresheet video signal so that it can be used by the Wide Screen monitor. The board adapts the video signal in two ways. First, the video signal goes through an amplifier which creates a common ground for the four signals (RGBS) and keeps the signal level of each at a level that the display can use. Second, the sync signal which is made up of both vertical and horizontal signals (composite sync) is altered so that horizontal and vertical are separated and supplied to the display through own wires. Refer to figure titled Sync Separator Board (SSB).

Maintenance of Brunswick Installed Wide Screens Although the monitors require very little maintenance it is suggested that you follow the following recommendations to keep them running at optimum performance.
Cleaning General Cleaning Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner.
Vent Holes Keep the vent holes on the back of the LCD clean of dirt and dust. It is recommended to wipe holes with a soft cloth a minimum of once per year. If using the internal cooling fan continuously, it’s recommended to wipe vent holes a minimum of once a month.
Adjustments Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability. Refer to the monitor vendor manual for specific adjustment procedures.
Maintenance of Bowling Center Supplied Wide Screen Overheads As each manufacturer has their own maintenance requirements, it is impossible to give specific recommendations for monitors supplied by a bowling center. As such it is important to follow the manufacturer's recommendations for your monitors. In general, it is important to make sure that any vent holes are clear of obstructions and the monitors is adjusted and cleaned for optimum readability. Always check with the manufacturer of your monitor before using any cleaning solution or glass cleaner.
