OPERATION
C.1.
Configuring BeFREE 20
The BeFREE 20 is a rather complex device with a number of programmable
settings/parameters provided for users to configure in accordance to the particular
application. To enable that feature Tipro supplies the respective programming utility
(
ChangeMe
) which operates only under Windows operating systems. It assists users to
define own set of parameters, save them into a file (for possible replication in the future)
and program into non-volatile memory of the Tipro controller for permanent storage.
It is also possible to dynamically modify certain settings (e.g. display brightness, LED
indicators, touchscreen disable/enable for cleaning purposes …) from the application
software. For that purpose Tipro provides the respective Windows API (
HID API
) and the
associated documentation.
BeFREE 20 can be programmed/configured externally, from another computer. That
computer needs to operate under Windows with ChangeMe utility installed and have one
serial COM port available. The BeFREE 20 may operate under any operating system or not
have it installed at all. This feature is obviously useful in cases when the BeFREE 20 runs a
non-Windows operating system, but it is also applicable in all Windows cases where
ChangeMe utility is not installed (e.g. to prevent uncontrolled modifications of the
settings). The cable required for programming can be ordered from Tipro (Ordering Code
TM-CGR) or rather easily made. The Reference [10] describes the procedure in detail.
C.2.
Applying BeFREE 20
The BeFREE 20 is typically used together with other
FREE
add-on modules, combined
in various compositions/configurations. An example with Handset modules is shown in
Figure C.1 below, along with its schematic representation (Figure C.2).
