Figure 1-1 and Figure 1-2 present the differences between basic module architecture and the
KJAVA one:
Figure 1-1: G24 - Basic Module Architecture
Figure 1-2: G24 - KJAVA Architecture
Two G24 hardware configurations are available:
• OEM - display and keypad are disabled
• HMI - display and keypad are enabled
Note: These two configurations look identical and can be identified by the model name printed
on the units.
In order to facilitate G24’s integration with external systems, an evaluation board (EVB) should
be used. The EVB consist of the following features:
• 70 pin connector for G24 placement
• SIM card interface
• Antenna
• DC power supply
• USB and RS232 interfaces
• Digital and analog audio interfaces
• Switches, jumpers and LEDs for miscellaneous controls and indications
For a detailed description of the EVB, see “Evaluation Board” and reference [2].
