However, there is no guarantee that interference will not occur in a particular installation.
Applicant: Motorola, INC FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 2 Hardware Interface Description The following sections describe in detail the Hardware Interface requirements and operation modes of the C-Lite Module. 2.1 Operating Modes The module should incorporate several operating modes. Each operating mode is different in the active features and interfaces.
Applicant: Motorola, INC 2.2 FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Power Supply The Module power supply must be a single external DC voltage source of 3.0V to 4.4V. TABLE 2 – Power supply signals Pin (s) Signal Name Description 1-4 GND Main ground connection for the module. 5-8 VCC DC supply input for the module. VIN = 3.0 V to 4.4 V IMAX ≤ 600 mA at TX/RX 2.2.
Applicant: Motorola, INC 2.3 FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Power On/Off Operation The Module power on and off process includes two primary phases, which are indicated at the interface connector by the hardware output signals RESET_N and CTS_N. The RESET_N signal indicates whether the module is powered on or off. When this signal is enabled (low), the module is powered-off. When it is disabled (high), the module is powered-on.
Applicant: Motorola, INC FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 FIGURE 4 – ON_N power-on timings VCC 200ms min ON_N <5000ms CTS_N RESET_N 2.3.1.2 Turning on the module using IGN This section applies only for the C-Lite standard model (without charger). To turn on the module this signal must be set high. The IGN signal must remain high for the duration of the module’s operation. The module powers down when the IGN signal is returned to its low state.
Applicant: Motorola, INC 2.3.2.1 FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Turning off the module using ON_N The ON_N signal is set high through an internal pull up resistor when power is applied to the module. Asserting the ON_N signal low for a minimum of 1.5 seconds will turn the module off. This will initiate a normal power-off process, which includes disabling of all applications interfaces (UART, SIM card, audio, etc.) and closing the network connection.
Applicant: Motorola, INC 2.3.2.3 FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Turning off the module using AT+MRST The AT+MRST command initiates a system reset operation, which powers off the module. This command emulates the ON_N signal operation for power off. 2.3.2.4 Power Loss shut down A low power shut down occurs when the module senses the external power supply is below the minimal operating level of 3.0V. The module will respond by powering down automatically. 2.
Applicant: Motorola, INC ATS24 Sleep Module FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Idle Disabled CTS_N Enabled TXD_N or RXD_N 2.4.2 Serial Interface during Low Power Mode During low power mode the serial interfaces are inactive. The module wakes up periodically from low power mode to page the network for any incoming calls or data. After this short paging is completed, it returns to low power mode.
Applicant: Motorola, INC FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Temporary termination of low power mode occurs when the module switches from Sleep mode to Idle mode for a defined period, and then returns automatically to Sleep mode. Using the WKUPI_N signal The WKUPI_N signal is an active low input, which is set high by default. By asserting this signal low the application can wake-up the module from low power mode and switch to Idle mode.
Applicant: Motorola, INC Sleep Module FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 ATS24 Idle Disabled CTS_N Enabled TXD_N or RXD_N 2.4.3.2 Permanent termination of Low Power Mode The module low power mode is enabled and disabled by the ATS24 command. To permanently terminate the low power mode, the ATS24 = 0 command must be used. Setting ATS24 = 0 disables the currently active low power mode and switches the module to Idle mode.
Applicant: Motorola, INC 2.5 FCC ID: IHDP56JE1 C24 Hardware Interface Manual Version 0.3 Real Time Clock The module incorporates a Real Time Clock (RTC) mechanism that performs many internal functions, one of which is keeping time and alarm operation. The RTC subsystem is embedded in the module and operates in all the different operating modes (Off, Idle, Sleep), as long as power is supplied above the minimum operating level.
