#99-02 Released March 18, 1999 50' Serial/Power Cable SMART Board™ 500 Series Cables: Using Extended Serial/Power Cables Preventing Electrostatic Discharge Damage When modifying or extending the 20' serial/power cable (#93-059-00) supplied by SMART Technologies with SMART Board 500 series systems, precautions must be taken to ensure that the new serial cable is grounded from connector shell to connector shell. Systems in the 500 series require a ground path through the serial/power cable. When working with the Board, users may introduce static to the system via the Board or the SMART Pen Tray™ tool sensors. Without the static ground path contained in the serial/power cable, the SC6 serial controller inside the Pen Tray may be damaged. Therefore, when modifying the serial cable, this ground path must be maintained. Refer to the following figures for details on cable construction.

Any extended cables not supplied by SMART must be connected to a cable that is supplied by SMART at either the Board or the computer end. Orientation of the SMART serial cable must be maintained with P1 directed towards the Board and P2 directed towards the computer. If you are unable to provide a static ground path through the extended serial cable, an external power supply with a ground connector to the building ground must be used as an alternative. A suitable grounded 12 VDC power supply (#60012) is available from SMART Technologies. If you are using a power supply not provided by SMART Technologies, ensure that it has the same characteristics as the 12 VDC power supply listed on page 2. The power supply must also have the negative polarity outside barrel of the 12 VDC coax connector connected to the ground terminal on the AC power cable to provide the static ground path. 1 Alternative to the Keyboard Power Cable The keyboard power cable (#93-061-00 (PS/2), #93-062-00 (XT) or #93-060-00 (Mac)) supplied by SMART Technologies can only be used with a serial cable to a maximum of 20'. Any extra length beyond 20' could limit the Pen Tray voltage to less than the 5VDC necessary to power the system. If you need to extend the serial cable beyond 20', you must connect an external power supply to the power socket (P3) in the DB9 connector to the PC serial port (P2) to provide the required voltage. P1 (DB9 female to SMART Board) P2 (DB9 female to PC serial port) P3 (power socket) external power supply Keyboard Power Cable Connecting to Power Socket in Serial Cable An external power supply must have the following characteristics: • 2.1 mm inner diameter — positive center post • 5.5 mm outer diameter — negative outer barrel • 6 VDC to 12 VDC output • minimum 200 mA output IMPORTANT: It is critical that the 12V power connector polarity be observed. Reversed polarity will open the internal fuse in the serial cable, thus destroying the cable. The fuse has been molded inside the hood (P3) of the serial connector and cannot be repaired. If the fuse inside the serial cable is open, the green LED power light on the hood of the cable will not illuminate. Power will not reach the SMART Board, and the Ready Light on the Board will not illuminate. Serial/Power Cable Options The following serial/power cable options are available from SMART Technologies: • 20' serial cable — #93-059-00 • 4' serial cable — #93-079-00 • 50' serial cable — #93-067-00 • Angle adapter — #93-078-00 • 12 VDC external power supply — #60-001, North America 120V — #60-004, Europe 230V — #60-005, UK 240V — #60-007, Japan 100V — #60-010, South Africa 240V — #60-012, universal, grounded 2 NOTE: The angle adapter is used to adjust the direction of the connection made between the Board and the serial cable by 90 degrees. When using the adapter, the connection may be made horizontally from behind the Board, rather than from below. Two adapters can be used together to place the serial cable connection behind the SB5 if the Board is installed 0.75 inches away from the wall. Noisy Writing Solution when Using External Power Supplies Pen Trays containing v6.6 firmware may have difficulties with some unregulated 12V external power supplies because the unregulated output exceeds 18 VDC, resulting in noisy writing. If your Board has problems with noisy writing, first complete the following steps to identify the firmware inside the SMART Pen Tray: 1. Open the SMART Board driver window. 2. Select Error Log from the Board menu. 3. Select the Version Info button. 4. Information similar to the following will be displayed. GETTING VERSION INFORMATION COM 2 check sum: 0x8916 COM 2 hardware version: 6.6 COM 2 hardware model #: 130/6 5. Locate the firmware version inside your Pen Tray. The firmware version listed above has been bolded. To resolve the noisy writing problem, you should use an external power supply with 9 VDC output. You can purchase these power supplies locally or contact SMART Technologies to make arrangements to receive the appropriate power supply. NOTE: If purchasing a 9 VDC external power supply locally, ensure that it has the same characteristics as the 12 VDC power supply listed on page 2. 3 ©1999 SMART Technologies Inc.
