Table 6: Pin-out of the 4-pin Dual-In-Line header connectors J107, J108 and J109 available on the ADP-L4 adapter board to route
the UART1, UART2 and/or UART3 interface of the TOBY-L4 module up to the DIL B2B connector, and the Cellular USB connector
Two jumper sockets need to be inserted on the related 4-pin DIL header in order to provide the connection
of the UART1 (using the 4-pin DIL header J107), or the UART2 (using the 4-pin DIL header J108), or the
UART3 (using the 4-pin DIL header J109), inserting one jumper socket on pins 1 and 2, and one jumper
socket on pins 3 and 4.
The connection of the UART1, UART2 and UART3 interface is mutually exclusive: only one interface at a
time can be connected from the module up to the DIL B2B connector and the Cellular USB connector.
The pins / interfaces that are not supported by a specific TOBY-L4 module product version should not be
driven by an external device (see the TOBY-L4 series Data Sheet [2] and the TOBY-L4 series System
Integration Manual [3] for the features supported by each TOBY-L4 module product version).

1.7 Software installation

The USB drivers are available with the EVK-L4. 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.
