Getting Started Guide

Setting up the 932 is a matter of making connections and choosing the output you want.

The 932 supports many different handheld devices, and can produce many different types of outputs.

In the following sections we'll cover how to make these connections, and how to choose the mode you want.

Making the Connections

These things need to be connected:

  • Handheld devices - Plug the handheld device either directly into the 932, or connect it through a removable bundle.
  • Power supply
  • Computer output cable (USB, serial, parallel, or other) to the host computer.
  • Optional: Optical or TTL trigger.

    These connections are all made to ports on the 932 rear panel, which is described in more detail under 932 rear panel.

    Choosing the Use Mode

    Each output behavior is a "Use Mode". A brief descriptive list of the available modes is given in 932 Use Modes.

    Most users will only be interested in one or two of these modes.

    The choice of use mode is determined by:

  • Cabling to the host
  • Type of connected handheld device
  • Desired output format

    Your choices are made using the knob on the front panel, guided by the display.

    932 Front Panel

    The 932 front panel uses a shaft encoder and display to let the user choose among many operating modes, and also displays real-time activity using a bank of 10 green LED indicators.

    The shaft encoder works together with the display to allow choices from menus, using clockwise and counter-clockwise rotations and a push-click for selections.

    Front Panel Indicator Functions - Button Box Modes

    This drawing shows the front panel of the 932 with the indicator LEDs labeled as they would function in typical button box modes.

    In some modes the indicator LEDs are used to indicate motion (for the scroll wheel device, for instance) or activity (scanning gains in calibration modes, for example).

    Understanding the Display

    During typical use, the fields in the display have these meanings:
    Hardware interface type
    Handheld model number
    Mode Identifier
      USB                      001
      HID KEY 12345  
    Mode number

    So, in this case, a four button diamond handheld device is in use, and this is sending USB HID keyboard output '1','2','3', etc., for button presses.

    Pushing the knob, would cause the display to change to this:

        NO YES  

    Pushing the knob again immediately would revert the display to the previous one-- this is just a way to abort the change and go back to the mode that was active.

    If "YES" is selected (by turning the knob), these choices are presented:

          MODE SELECT  

    Turn the knob and then press to confirm your choice.

    These 3 ways of choosing a configuration are described in the next 3 sections.


    The AUTOCONFIGURE choice tells the interface to determine as much as it can about the connected handheld device and the cabling to the host computer. This should simplify the choices that need to be made by you.

    If a handheld device is connected when AUTOCONFIGURE starts, the interface will attempt to identify it and to set the gain properly on its channels. (Because the gain is automatically determined at this time, the system should work reliably both with and without removable bundles connected.)
    Also, if a cable (usually a serial cable or a USB cable) is connected to a host computer, the interface will identify that cable and limit the available mode choices to ones which are compatible with that cable. (For instance, only serial modes will be displayed if the serial cable is connected).

    So, in the case that you've connected both the handheld device and a cable to the host, you will normally see a display asking you to choose the output format you want. This is done by rotating the knob and pressing it to make a selection. The specific choices that will be presented depend on the handheld device and the output cabling that are detected, but a typical set of choices (for a button box, with USB cabling to the computer) would be:

          HID KEY 12345
          HID KEY NAR  

    The AUTOCONFIGURE approach is usually the best one to take, but there are situations in which it won't be able to automatically determine the type of handheld device which is connected.

    These devices can not be automatically identified:

  • older handheld devices (model numbers starting with HH- rather than HHSC- ; these have tubing with braided covering, rather than shiny plastic tubing)
  • devices that use shaft encoders for position or motion sensing (HHSC-TRK-1, HHSC-SCRL-1)


    MANUAL CONFIG available for several reasons. The biggest one is to provide compatibility with our earlier handheld devices (the HH series, as distinct from the present HHSC series) which cannot generally be identified by the 932 interface. In manual mode the interface will not attempt to recognize the handheld device.

    Use of this mode is fairly self-explanatory-- the knob is used to select the handheld type, the hardware interface for output, and the format for the output.


    This mode is intended to give users a simple way to return to settings they previously determined where correct. By selecting the mode using the number, the hardware interface, and output format are set at one time and no questions are asked.

    Switching Handheld Devices

    When you switch from one type of handheld device to another the 932 needs to be 'told' of this change. For instance, when you unplug a button box and connect a scroll-wheel device in its place, you should push the knob and and answer "YES" to "CHANGE MODES?".

    What Happens at Power-Up

    The 932 'wakes up' in the mode that was last active. For any of its channels that rely on calibration, it will use the saved gains. For other channels, such as regular button box channels, the gain will be automatically determined in the brief second while it turns on.

    The 932 does not attempt to identify the handheld device at power-up, though: it assumes the same one is connected that was connected last time it was used. So, if the handheld type that you have connected doesn't match what the display says, you should push the knob and set the Use Mode for your new setup.
