Programming Connector X3 and X4
All modules can be reprogrammed either by using the integrated programming interface or the
integrated bootloader via UART interface. On the Demo Board the UART has to be connected to
the USB interface on X7. Alternatively the integrated programming interface of the module can
be used to flash a new program into the module.
Connector X4 can be used to connect a programming device for all WiMOD radio modules
(except iM871A which has to be programmed via the programming connector on its Adapter
Board “Wireless M-Bus AB 1”). The necessary programming device depends on the connected
radio module. Table 3-6 shows the pinout of X4.

Warning: It cannot be guaranteed, that the chosen programming
device can be connected one-to-one to programming connector
X4. Contact us for further information.
Warning: The bootloader will be deleted if the integrated
programming interface is used. It is not possible to update the
modules firmware with the corresponding PC tool if the bootloader
has been deleted.
