The lower one, called EVB -WL3, contains the power supply and other peripherals for the u-blox SARA-R5 series cellular module (such as SIM card holder, reset button and power-on button). 2. The cellular adapter board, called ADP-R5, contains the u-blox SARA-R5 cellular module, antenna connectors for the cellular RF interface and the GNSS RF interface1 of the SARA-R5 module, USB connectors for the two UART interfaces and the USB interface of the SARA -R5 module, and the DIL header connectors (J300 and J301) making accessible interfaces of the SARA-R5 module. 3. The GNSS adapter board, called ADP -GNSS, contains the u -blox GNSS module, the GNSS antenna connector and the USB connector for the GNSS module. The cellular and the GNSS adapter board s are connected by means of male header board -to-board connectors provided on the bottom of the adapter boards and their corresponding female connectors provided on top of the lower board, called EVB-WL3. If the on-board / B2B switch (SW401) is set to “on -board”, then the single UART interface (with the default USIO variant 0 setting, or the USIO variant 1 setting) is available on DIL connector s on the cellular adapter board. It is routed up to the RS232 DB9 connector (J500) or the USB connector (J501) mounted on the EVB-WL3 board according to the settings of the mini-USB / DB9 switch (SW403). If the on-board / B2B switch (SW401) is set to “B2B”, then the two UART interfaces (with the +USIO variant 2, 3 or 4 setting) are available on the USB connector (J201) mounted on the cellular adapter board. The USB interface of the cellular module (available for diagnostic purpose only) is available on the native USB connector (J105) mounted on the cellular adapter board. Other SARA-R5 series peripherals are available on the dual-in-line male board-to-board connectors provided on the top layer of the cellular adapter board ( J300 and J301), which are pin -to-pin compatible to the connectors on the bottom layer of the adapter board. The lower board (EVB -WL3) is also designed to be used with other u -blox cellular adapter boards. It contains additional switches, jumpers, con nectors, LEDs and parts that may be only part ially described in Figure 1 or in this document, because they are intended for use only with other u -blox cellular modules. It is recommended to leave any additional connector unconnected and any additional switch in its default configuration. 1 EVK-R510M8S only.

1.7 Board setup

1. Insert a SIM card into the SIM card holder (J300 on the EVB-WL3). 2. Connect the cellular antenna provided with the evaluatio n kit box to the Cellular antenna SMA connector on the ADP-R5 (ANT connector for transmission and reception of LTE RF signals) 3. If the GNSS functionality is required: 3.1. For the EVK-R500S and EVK-R510S, connect the GNSS antenna provided with the evaluation kit box to the GNSS antenna SMA connector on the ADP -GNSS (J208) ; keep cellular GNSS detach switch (SW304) on “GNSS” position. 3.2. For the EVK-R510M8S, connect the GNSS antenna provided with the evaluation kit box to the GNSS antenna SMA connector on the ADP-R510M8S (J112); keep cellular GNSS detach switch (SW304) on “detach” position. Place the GNSS antenna in a location with a good view of the sky. 4. Connect the AC / DC +12 V power adapter provided with the evaluation kit box to the 9 – 18 V power input connector (J400 on the EVB-WL3). The LED DL401 lights blue. 5. Be sure to provide a jumper socket on both the Cellular VCC supply jumper s (J404 on the EVB-WL3, and J109 on the ADP-R5). These jumpers provide the connection from the 3.8 V output of the supply circuit on the EVB-WL3 to the VCC input of the module. 6. To enable the board power supply, turn the Main power switch (SW400 on the EVB-WL3) to the ON position. The LED DL400 lights green. 6.1. For the EVK-R510S, press the Cellular power -on button (SW302 on the EVB -WL3) to switch on the SARA-R510S cellular module. 6.2. For the EVK-R500S, the SARA-R500S cellular module switches on. For the EVK-R510M8S, the SARA-R510M8S cellular module switches on. 7. For communication via the cellular module’s UART interface, the following connection s are allowed and can be alternatively enabled in a mutually exclusive way (see Table 6 for the switch position and LED status): 7.1. Connect a USB cable to the mini USB connector on EVB-WL3 (Cellular USB, J501). The LED DL501 lights blue. When a USB cable is connected to th is mini USB connector, two COM ports are enabled in Windows: the single UART interface of the cellular module (with default USIO variant 0, or USIO variant 1) is available over the first COM port opened by the driver. 7.2. Connect an RS232 cable to the DB9 connector on EVB-WL3 (Cellular RS232, J500). 7.3. Connect a USB cable to the mini USB connector on ADP -R5 (Cellular USB, J201). The LED DS201 lights blue. When a USB cable is connected to this mini USB connect or, two COM ports are enabled in Windows : the two UART interfaces of the cellular module (with UART variant 2, 3, or 4 ) are respectively available over the two numbered COM port s opened by the driver.

Run an AT terminal application (e.g. the u -blox m -center tool) selecting an AT port, with these settings: o Data rate: 115,200 bit/s o Data bits: 8 o Parity: N o Stop bits: 1 o Flow control: HW See Appendix A for how to configure the u-blox m-center AT terminal for Windows. 8. To switch off the EVK -R5, send the +CPWR OFF AT command. Make sure to use this command before switching off the main power, otherwise settings and configuration parameters may not be saved in the internal non-volatile memory of the cellular module.
