BeFREE 20 – TECHNICAL OVERVIEW
A.
GENERAL INFORMATION
The
BeFREE 20
(BF 20) is a member of the modular
FREE
(also referred to as
FREE/FREE+/BeFREE) product family, integrating a 15.0” touchmonitor, a computer and
an intercom device. It is compatible and combinable with all existing
FREE
modules. The
touchmonitor comprises a high-brightness TFT LCD and 5-wire resistive touchscreen. The
computer is based on a main-board with Intel quad-core Celeron processor (
J1900
) and a
solid state disk. Thanks to low-power components and the corresponding electronic and
thermal design the BeFREE 20 is completely silent and without moving parts.
The Intercom section consists of a goose-neck microphone, illuminated PTT key, stereo
loudspeakers, two volume control knobs and two VU-meters. Its primary audio interface is
USB via two independent Audio Codecs, but it is also connected to the analogue sound
card of the embedded computer. This dual interface results in up to six listening (output)
channels and three parallel recording (input) channels. Status of the PTT key is reported
via HID Keyboard and/or HID Telephony interface.
