SD/MMC and SIM Card Slots
The SD and SIM card slots reside under the batteries near the base of the dome.
The SD card slot is located to the left of the MINTER inside the battery pocket ( Figure 1-9 )
and connects an optional SD card to the receiver board to provide memory. Once installed, the
SD card usually remains inside the receiver. The data that resides on the SD card can be
accessed via the serial port, or Bluetooth wireless technology. A secure digital card can be
purchased at a local computer supply store.
The SIM card slot is located to the inside the battery pocket and allows a standard SIM card
to be installed in the receiver. Once installed, the SIM card provides a unique identification for
the receiver's GSM module and enables the receiver's GSM functionality based on the
subscribed ser-vices ( the receiver board accesses the GSM module which accesses the SIM
card ). The SIM card usually remains inside the receiver. The GSM module with the SIM card
installed can be accessed via
Modem-TPS
for configuration purposes. A SIM card can be
purchased from a local cellular provider.
