    New Extension Board for all GM862 modules
    With GM862-PCS it was necessary to create a Extension Board and Starter Kit.

    current Extension board RS-EB-S1:
    -Connector for the support of CMOS camera
    -Connector for the support of LI battery
    -Automatic power on
    -Power on with switcher
    -D-Sub 9 Pin connector to RS232 on V.28 Level (+/- 12 V)
    -Connector to use the GM862 RS232 lines on CMOS level
    -Two LEDs ( Power On , Status LED)
    -Connector for Audio accessories
    -Standard connector for power
    -50 pin connector that supports all GM862 pins
    -Schematic diagrams

    -Li Ion batteries or LI Polymer battery
    -Audio accessories like loudspeakers, microphones, analogue hand free kits and digital hands free kits)
    -Plastic enclosure with holes for RS232 and RF cable
    -Wall plugged AC power supply

    With plastic enclosure and RF cable you are very close to a ready product i.e. GSM-Modem.
    You only need to develop the rest of you application and can just plug it on to the 50 pin connector on the RS-EB-S2 baord.
    The result is that you can show a prototype to your customers very quickly.
