I want you design an interface/controller card which will be connected to an android 4.0 tablet via USB port. Card should have following min. ports and i/o on it.

- 1 USB port to connect to android tablet

- 1 analog port to read 4-20 mAmp devices

- 1 Onewire digital interface to read temperature sensors like DS 18s20

- 2 RS485 port for communication with external devices

- 1 RS232 port for Thermal Printer

- 5 Relay to control external devices

- 2 analog input to read shaft encoders

- 1 Ethernet port (optional not mendatory)

Designer should design pcb and also write a sample android application which can :

- read&show shaft encoder turns

- read&show temp values

- open or close relays based on predefined conditions

- read&show analog devices

- print out data it reads or processed

- read&show read values from a modbus device via rs485

- send processed data real time from rs485 ports.

Please keep in mind that application should be designed to work 7 day 24 hours. All source codes and pcb design datas will be given to us. Also will be signed a Non-Disclosure Agreement.
