4 3 Overview The Evaluation Kit supports the easy testing of applications with the MD32. Three Demo- Boxes allow You to build up a DECT-System and are used for functional tests of an application. 4 Getting started First step: connect the RS232 cable to the (X2) and a free serial interface at the. Connect the power supply (X1) and the handset (if used, X3) to plug together the Basic Configuration. Second step: install the configuration-sw (see SW Installation Guide /2/) RS 232 cable Handset Handset cord Basic Configuration X2 X1 X3 AC-Adaptor Fig. 4-1 Basic Configuration At last use the configuration SW to chose the operation mode and for subscription. The is ready for use now. The following figure shows the arrangement and pinning of Interface connectors on the : FFC-Jumper Test pins X4 MD32 Application Module RS X2 6 9 Handset X3 Power Supply X4 X5 Lock Indication Dummy LED 20 1 DECT-Engine MD32 MD32 Fig. 4-2 / Connector Overview Preliminary Technical Description 4-4 Issue:

5 5 Demonstration Examples 1) With the GAP-PP-mode the can subscribe to a GAP base station. The is used to set up the voice connection to the Handset: GAP-FP DECT-Module configured as GAP-PP X2 X1 X3 e.g. GIGASET 2010 PSTN Fig. 4-3 GAP-PP Demonstration 2) Two s can be used to replace a Zero-Modem-cable between two s.
