Speaker
The speaker is located on the front of the MX3X above the Power button.
The MX3X Speaker has a loudness of at least 90 dB (2700 Hz) at 10 cm measured from the front
of the unit. The Speaker volume is adjustable via the keypad or the Control Panel or by an
application through the use of an API call. There are 16 distinct volume levels. The minimum
volume level is 0 (no sound) with a default setting of maximum non-distorted volume. The
volume sticks at maximum and minimum levels.
The speaker is disabled when a headset is plugged into the Audio Jack on the endcap.
Speaker volume is enabled and adjusted using the Control Panel "Volume & Sounds" option.
After the speaker has been enabled using the Control Panel option, speaker volume is adjusted
using the 2
nd
+ <F8> key sequence, if desired.
Operational “beeps” are emitted from the speaker.
Infrared (IR) Port
Figure 2-14 Infrared Port - COM2 Port
At the back of the MX3X computer there is an Infrared (IR) Data Port. The IR Port is designed to
provide a data link between the MX3X and a similarly equipped piece of equipment such as a
printer. The IR port is the MX3X’s COM 2 port and is a bi-directional half-duplex communication
port. It supports baud rates up to 115k, SIR (Slow IR). It will support serial port emulation, as
well as IrDA and Winsock over IR protocols. It also supports ActiveSync.
The IR operating envelope has a distance range of 2 cm (.79 inches) to 1 meter (3.2 feet) with a
viewing angle of 30 degrees.
The MX3X uses IrDA protocol to send data in both directions, but not simultaneously. When
sending data through the IR port, make sure the IR port on the first MX3X and the IR port on the
second MX3X are in close proximity to each other. IrDA is not required and not used by terminal
emulation programs.
When the MX3X is docked in a cradle, the Status LED on the cradle is red when data is being
transmitted through the IR port.
