JP6 & JP7: Base Address Jumpers

The base address selection jumpers (A3 through A8) allow you to set the base address of the first UART that connects to the GPS module and

the second UART that connects to the GSM module. Any software that accesses the board will do so through reads and writes to the I/O

address set by the jumpers. To function properly, the I/O address the software is expecting must match the base address set by the jumpers.

As shown in the figure below, A3 is located at the left end of the jumper block, while A8 is located at the right end:

The table on the following pages shows the possible base address settings for the COM16155. All base addresses are in hexadecimal. An ‘X’

indicates a closed jumper, while an empty cell indicates an open jumper.
