We start with a global overview of the APEXAR PRO modules, in this secction you find the operational requirements, dimensions and key features.

Then we will explore the main board of the APEXAR PRO module allowing you to get more familliar with the available connectors.

The APEXAR PRO module was designed not only to be integrated with other hardware but also to be expanded and customized. In the mechanical data section and expansion connector section along with the module schematics you find all you need to build an expansion card if it's needed.

9 SERIAL INTERFACES

The APEXAR PRO offers four serial ports with different features:

Name Default electricallevels supported Connector Components to be removed

for TTL levels support

DGBU (Debug) RS232 P3 -

Port 0 RS485 P2 R25

Port 1 RS232 P2 R21, R22

Port 2 TTL P2 -Table 7 – Serial interfaces.

All the signals that belong to the ports 0, 1 and 2 are mapped to the expansion connector. The debug port has it own dedicated connector.

By default the APEXAR PRO module serial ports are configured to operate according to the level standards described above. However, TTL levels signals are available also for port 0 and port 1. This change can be accomplished by removing from the PCB the associated components listed above.

WARNING: When using a serial port you must not use any of the other signals associated with it for any other purpose.

Example: Consider the case you are using the serial port 1 thru the RS232 interface (pins: 13, 14, 15, 16). Then you can not use the pins intended for the TTL interface (pins: 9, 10, 25, 26).

(*) This signal is connected to a fixed logic levels (for more details refer to the comunication interfaces schematic).



10 THE RESET SIGNAL

This signal is connected to the reset line of the microprocessor present at the APEXAR SOM. Driving it to a HI state will reboot the system.

This signal is available in the expansion connector (see expansion connector pin assignment).You can generate a reset event by pressing the reset button located at the mainboard of the

APEXAR PRO module.

11 THE NAND DISABLE BUTTON

By holding this button the nand flash memory present at the APEXAR SOM will be disabled. This procedure is necessary when the developer/production user wants to upload data to the nand flash, this includes the bootstrap, the u-boot, the kernel and the root file system [1].

WARNING: Pressing or holding the nand disable button while the module is operational may crash the system and also may corrupt some data loaded in the NAND flash.
