General Product Description 2.1 SIM Card Holder Support The HD Traffic Receiver Module has on the backside of the PCB, the necessary pads to manually solder a SIM card holder. The type of the SIM card holder to be used is UNCR2103D006-0 of JESS-LINK. 2.2 Supply voltage The external power supply must be connected to Vpower signal and must fulfill the following requirements: Nominal operating voltage 3.8 V• Operating voltage range 3.•4 V - 4.2 V NOTE: 1. Operating voltage range must never be exceeded; care must be taken in order to fulfill min/max voltage requirements. 2. The minimum transmission burst voltage in worst network conduction should be kept 3.1V above. 2.3 Power consumption The typical current consumption of HD Traffic Receiver Module is: Power off current (Typical) <= 60 uA

The following table shows the logic level specifications used in the module interface circuits: Absolute Maximum Ratings –Not Functional Parameter Min Max Input level on any digital pin when on - 0.3 V + 3.75 V Input voltage on any analog pins when on - 0.3 V + 3.0 V Operating Range –Interface level (2.8V CMOS) Level Min Max Input high level 2.1 V 3.3 V Input low level 0 V 0.5 V Output high level 2.2 V 3.0 V Output low level 0 V 0.35 V Operating Range –Interface level (2.0V CMOS) Level Min Max Input high level 1.6 V 3.3 V

Whenever this signal is pulled low, the module is reset. When the device is reset it stops any operation and after the release of the reset it is unconditionally rebooted, without doing any detach operation from the network where it is registered. This behavior is not like a proper shut down because any GSM device is requested to issue a detach request on turn off. For this reason the Reset signal must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stuck waiting for some network response. The RESET is internally controlled on start-up to achieve always a proper power-on reset sequence, so there's no need to control this pin on start-up. It may only be used to reset a device already on that is not responding to any command. Reset Signal Operating levels: Signal Min Max RESET Input high 2.2 V* 3.3 V RESET Input low 0 V 0.2 V * This signal is internally pulled up so the pin can be left floating if not used If unused, this signal may be left unconnected. If used, then it must always be connected with an open collector transistor, to allow the internal circuitry the power on reset and under voltage lockout functions. 2.8 2.75V_out power output A regulated power supply output is provided in order to supply small devices from module. This output is active when the module is ON and goes off when module is shut down. The operating range characteristics of the supply are: Operating Range –2.75V_out power supply Min Typical Max Output voltage 2.75 V 2.85 V 2.95 V

Moreover, it has the antenna pads on the PCB to accept spring clips for antenna contact. 2.15 Power up / down scenarios In general, be sure not to turn on the module while it is out of the operating range of voltage in Chapter 2.2. 2.15.1 Turn on the module The module can be activated via SYS_EN signal. When switch on the Module the SYS_EN signal needs to be driven to high level for at least 150ms 2.15.3 Turn off the module To switching the module off the following procedures may be used: ＊ Normal shutdown:
Doc No： Topic： User Manual of TomTom HD Traffic Receiver Module Ver： 1.1 Page： 14 / 40 Page 14 of 40 Software controlled by sending the AT command over the serial application interface. ＊ Automatic shutdown: Takes effect if under voltage is detected. 2.15.4 Turn off The module using AT command The best and safest approach to powering down the module is to issue the AT command. This procedure let the module log off from network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to as POWER OFF mode. In this mode, only the RTC stays active. Command syntax: AT+CPWROFF Command Possible responses AT+CPWROFF Note: switch off the module OK Or CME ERROR: <error> Test command AT+CPWROFF=? OK After sending AT+CPWROFF do not enter any other AT command. There are two ways to verify when the module turns off. ＊ Wait for the “OK”. It indicates that data have been stored in the non-volatile memory and the module turn off in less than 1 second. ＊ Also, you can monitor the 2.75V_out pin. The low state of 2.75V_out definitely that the module is switched off. When the module is in POWER OFF mode the application interface is switched off and must not be fed from any other source. Therefore, your application must be designed to avoid any current flow into any digital pins of the application interface. 2.15.5 Inserted and removal action direction These models are made very thin so that they may be smaller in size and light in weight than before. Take care not to give then excessive force and insert by sliding when mating them together or un-mating them. Otherwise, breakage may result. To prevent damage from incorrect insertions please confirm the correct position before mating connection.
