Hardware Setup

If your hardware is already connected and setup, you can skip this step and proceed with Device Cloud setup.

Tower assembly

Detailed assembly instructions can be found within the Quick Start Guide inside the TWR-ELEV module.

To assemble the tower you will need the following components:

• A supported Tower Kit microcontroller module (TWR-K60N512, TWR-K53N512 or TWR-K70F120M).
• Primary and Secondary tower elevator modules (TWR-ELEV).
• A serial module including USB host/device/OTG, Ethernet, CAN, RS232 and RS485 (TWR-SER).

Using these components, connect the TWR-Kxx and TWR-SER boards via the tower elevators (TWR-ELEV). Make sure the primary side (often marked with a white stripe) goes into the elevator board with the white edges.

When finished, your tower should resemble the following:

Hardware configuration

For proper hardware configuration you will need to perform the following changes in the hardware:

1. On the TWR-K60N512 board: Change J6 to pins 2-3 to use the 50Mhz clock from the TWR-SER board.
   On the TWR-K53N512 board: Change J11 to pins 2-3 to use the 50Mhz clock from the TWR-SER board.
   On the TWR-K70F120M board: Change J18 to pins 2-3 to use the 50Mhz clock from the TWR-SER board.
2. On the TWR-SER board:
   1. Change J2 to pins 3-4 to give a 50Mhz clock to the PHY.
   2. Add jumper to J3 pins 2-3 to bring up the 50Mhz clock from the TWR-SER.
   3. Add jumper to J12 pins 9-10 to put into RMII mode.
   4. If you do not have extra jumpers, you can use the ones on CAN_SEL (J5) on the TWR-SER board.
   
   

   If you'd like to restore default settings after you've completed the steps described within this guide, default jumper settings can be found in the Quick Start Guide for the TWR-Kxx module and TWR-SER modules.

3. Finally, you need to make the following tower connections:
   1. Connect an Ethernet cable between the TWR-SER board and an Ethernet port of your PC.
   2. Connect a mini-B USB cable between the TWR-Kxx board and a USB port of your PC.
      
      

The OSJTag firmware should be updated to the latest version in order to take advantage of all the features it offers (such as a virtual serial port). If you have not updated your OSJTag firmware yet, follow these instructions.
