Transmitter
The transmitter is shown by itself in Figure 2. The transmitter does not have an on/off switch,
and is always ready to transmit. There are 9 pitch/location buttons, a cancel button, and two
catcher volume adjustment buttons. Also, the transmitter has a micro USB port through which
the transmitter is charged and can receive firmware upgrades, an antenna wire, and a status
LED above the cancel button. A white LED is also provided, whose function will be described
below.
The same nine (9) buttons are used to select both the type of pitch (“pitch type”) and pitch
location (“location”). Currently, the pitches corresponding to buttons 1-9 (as numbered in the
photo) are 1-four-seam fastball, 2-curveball, 3-slider, 4-change up, 5-cutter, 6-sinker, 7-splitter,
8-screwball, 9-two-seamfastball. The locations also correspond to the same buttons 1-9, and
are arranged in an intuitive pattern. Currently, the locations are 1-high inside, 2-high middle, 3-
high outside, 4-middle inside, 5-middle middle, 6-middle outside, 7-low inside, 8-low middle,
9-low outside. The wider spacings between buttons 4 and 5 and between buttons 5 and 6 also
allow the catcher to instantly know where his thumb is located on the transmitter keypad
without looking.
