The SIM IC interface insures the power on (SIMVCC) of the SIM Chip and the communication with it through a data signal (SIMDAT), a clock signal (SIMCLK) and a reset signal (SIMRST). Switch S601 to position "2" to use this SIM. 4.2.2. SIM CARD The SIM Card interface is compatible with the ISO 7816-3 IC card standard required by the GSM 11.11 Phase 2+ standard. The module also supports Release 99 of the SIM Toolkit recommendation and supports a Fixed Dialling Number directory. The SIM Card interface insures the detection (SIMCD), the power on (SIMVCC) of the SIM Card and the communication with it through a data signal (SIMDAT), a clock signal (SIMCLK) and a reset signal (SIMRST). Switch S601 to position "1" to use this SIM card.

When the mini coaxial cable is used : connect the cable to P104 on one side and to the Hilo module coaxial antenna out on the other side. Then connect an antenna to P103. In this configuration, if the Hilo development kit is used to make some accurate radio performances measurements, please add a tape on the E101 and E102 to avoid to create a "stub" effect resulting in radio performance losses.
