3 3.1 Operation Introduction Once you have installed and configured the CrossCheck GSM/GPRS unit, it is ready for operation. When power is applied, the CrossCheck GSM/GPRS unit operates automatically without user intervention. This chapter provides a basic overview of how the CrossCheck GSM/GPRS unit operates. 3.2 LED Indicators The CrossCheck GSM/GPRS unit has two LED indicators, as shown in Figure 3.1.
Operation 3 The GPS and GPRS LED indicators have three states: on, off, and flash. When both indicators are off, the CrossCheck GSM/GPRS unit’s power is off. When one or both LED indicators are on or flashing, the power is on. 3.2.1 LED states Table 3.1 identifies the GPS LED states. Table 3.1 GPS (green) LED states State Meaning On Computing GPS position fixes. Flash Searching, or not computing GPS position fixes. Off No power is available, or the ignition is off. Table 3.
3 3.3 Operation • The GPS LED flashes once, turns off for approximately five seconds, then turns on for approximately two seconds, flashes until the first position fix is computed, then stays on. • The GPRS LED flashes once, turns off for approximately five seconds, flashes until the unit is registered with a GPRS network, then stays on. GPS Receiver Operation When the CrossCheck GSM/GPRS unit is powered on, the GPS receiver initializes with the last known position if one is available.
Operation 3.4 3 Registration When the CrossCheck GSM/GPRS unit is turned on, it checks whether a SIM card is installed. If a SIM card is not detected or has not been installed properly, the amber LED flashes rapidly. If a SIM card is installed, the unit tries to register with the appropriate GPRS network. If the unit cannot detect a GPRS network, the amber GPRS LED flashes slowly.
