    Cables to connect the ServSwitch Uno/Duo USB to each of your computer keyboard, video and mouse ports. There are three main types of cable available from Black Box that connect to PS/2, USB or Sun systems. Each cable type is available in various lengths. You may also need one or more cabling adapters if you have older type 5-pin DIN keyboard connectors, 9-pin serial mouse connectors or 13W3 video connectors.
  • Page 16 To ensure that you have the right adapter, either purchase this from Black Box or check your adapter against the wiring specification given in Appendix A.
  • Page 17: Mounting The Servswitch Uno/Duo

    KVM (Keyboard, Video monitor, Mouse) sets then you do not need to use the same brands or mix of devices on each user port. Next, connect each computer system unit in turn using the Black Box interface cables that you have purchased for use with the ServSwitch Uno/Duo USB (see Appendix A for cable specifications and part codes).
  • Page 18 Figure 3 - ServSwitch Uno/Duo USB cables. See appendix A for part codes and ordering information To connect PCs with serial mouse connections and AT style keyboard connections use the PC cable together with the adapters specified in appendix A. If you have an existing 6-pin mini-DIN to 9-pin serial adapter that came with a mouse it may not be suitable for use with the ServSwitch Uno/Duo USB as there are several different standard wiring configurations for these adapters.
  • Page 19: Configuring Your Computers

    To connect Sun computers with older style 13W3 video connections you will need to use the Sun cable together with a 13W3 to 15 way D-type video adapter. The ServSwitch Uno/Duo USB is now ready for connection to the mains using the mains power adapter supplied.

See section 4.19 for details on using the SEND DATA TO RS232 PORT and READ DATA FROM RS232 PORT functions.
  • Page 58: Resetting User Port Keyboards And Mice

    Although it is theoretically possible to select computers on cascaded units by pressing the hotkeys and then typing in the port address this would be highly confusing for users and is not generally recommended. Consequently it is normally advisable to use the on-screen menu to select computers on cascaded units. However it is sometimes useful to be able to connect to ports on cascaded units via a specific cascade cable (rather than the first available of a group) in order to check that the cabling is working as expected.
  • Page 59: Using The Black Box Extender

    You will also need one of the following cables to interface the extender to the Uno / Duo USB EHN428-006 When using an Black Box extender we highly recommend that you set the extender's hotkeys to be different to the ServSwitch's hotkeys to avoid any confusion.
