EVK-R4 - User Guide

The EVK-R4 is formed by three boards:

 The lower one, called EVB-WL3, contains the power supply and other peripherals for the SARA-R4 series

cellular module (SIM card holder, Reset button and Power-on button).

 The cellular adapter board, called ADP-R4, contains the SARA-R4 cellular module, the cellular antenna

connector and the USB connector for the cellular module.

 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 boards 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.

The USB interface of the cellular module is available on the native USB connector on the cellular adapter board, while the other peripherals are available on the dual-in-line male board-to-board connectors provided on the top layer of the cellular adapter board, which are pin-to-pin compatible to the connectors on the bottom layer of the adapter board.

The lower board (EVB-WL3) is designed to also be used with other u-blox cellular adapter boards. It contains additional switches, jumpers, connectors, LEDs and parts that are only partially described in Figure 1 and 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 to leave any additional switch in its default configuration.

1.8 Software installation

The USB drivers for Windows operating systems are available with the EVK-R4. Executable files can be downloaded from www.u-blox.com/evk-downloads and saved to any location on the computer hard drive. The installation can be started by running the executable file on a computer with the Windows operating system.

1.9 Board setup

1. Insert a SIM card into the SIM card holder (J300 on the EVB).

2. Connect the cellular antenna provided with the evaluation kit box to the Cellular antenna SMA connector

on the ADP-R4 (ANT connector for transmission and reception of LTE RF signals)

3. If the GNSS functionality is required, connect the GNSS antenna provided with the evaluation kit box to the

GNSS antenna SMA connector on the EVB. Place the GNSS antenna in a location with a good view of the sky.

Interface to the GNSS module is not supported by the “00” and “01” product versions of SARA-R4

modules1.

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). The LED DL401 lights blue.

5. Be sure to provide a jumper socket on the Cellular VCC supply jumper (J404 on the EVB). This provides the

connection from the 3.8 V output of the supply circuit on the EVB to the VCC input of the module.

6. To enable the board power supply, turn the Main power switch (SW400 on the EVB) to the ON position.

The LED DL400 lights green.

7. For communication via the cellular module’s USB interface, connect a USB cable to the Cellular native USB

connector on the ADP-R4. The related LED lights blue.

After the end of the module boot (refer to point 9 for the procedure to switch-on the cellular module), the COM ports listed in Table 6 are enabled by the Windows USB driver (details as the numbering of the ports can be seen via the Windows Device Manager):

Table 6: Cellular USB interface configuration

Run an AT terminal application (e.g. the u-blox m-center tool) selecting an AT port.

See Appendix A for how to configure the u-blox m-center AT terminal for Windows.

8. For communication via the cellular module’s UART interface, the following connections are allowed and can

be alternatively enabled in a mutually exclusive way (see Table 7 for the switch position and LED status):

a. Connect a USB cable to the mini USB connector (Cellular USB, J501 on EVB). The LED DL501 lights

blue. When a USB cable is connected to the mini USB connector, two COM ports are enabled in Windows (the numbering of the COM ports can be seen via the Windows Device Manager). The serial port for AT commands is available over the first numbered COM port opened by the driver.

b. Connect an RS232 cable to the DB9 connector (Cellular RS232, J500 on EVB).

B Setting up a cellular packet data connection on a

Windows PC

This section describes how to set up a packet data connection with the Windows 7 operating systems (for PC) and EVK-R4, using the TCP/IP stack of the PC (external TCP/IP stack).

The following examples describe how to install and configure two different kinds of modem on Windows:

1. Over the UART interface of the cellular module: connect the Windows PC to the Cellular USB connector

(J501 on EVB) or the Cellular RS232 connector (J500 on the EVB)

2. Over the native USB interface of the cellular module: connect the Windows PC to the Cellular Native USB

connector (J105 on the ADP)

B.1 How to install and configure a modem data connection over UART

This example describes how to install and configure a data connection on a PC with the Windows 7 operating system. This uses the TCP/IP stack of the PC over the UART interface of the cellular module connected to the Windows PC by the Cellular USB connector (J501 on EVB) or the Cellular RS232 connector (J500 on the EVB).

D Current consumption measurement

The current consumption of SARA-R4 series modules can be measured on the EVK-R4 by removing the jumper socket from the Cellular VCC supply jumper (J404 on the EVB), described in Figure 6.

Figure 6: Jumper socket to be removed for SARA-R4 series modules current consumption measurement

A suitable external digital multi-meter (as for example the Agilent 34410A or 34411A) can be used for current consumption measurements. In this case, the 3.8 V supply circuit on the EVB will supply the SARA-R4 module mounted on the adapter board, with the digital multi-meter placed in series as illustrated in Figure 7.

Figure 7: Block diagram of current consumption setup for SARA-R4 series modules

Alternatively, a suitable external DC power supply with the dynamic current measurement capabilities (as for example, the Agilent 66319B/D) can be used for current consumption measurements, acting also as the 3.8 V supply source for the SARA-R4 module mounted on the adapter board.
