4.1 Set Up EK-TM4C1294XL Board and PC

  1. Connect one end of the Ethernet cable to the Ethernet jack on EK-TM4C1294XL board and the other end to LAN with DHCP server present (like router).
  2. For the schematic and connections for a simple circuit to level shift the CMOS/TTL signal of the universal asynchronous receiver/transmitter (UART) on EK-TM4C1294XL board to RS-232 levels, see Section 7.1 and Section 7.2.
  3. Connect one end of a DB9 cable as described in Section 7.1 and Section 7.2 and the other end to the PC. If the PC does not have a DB9 port, then use a DB9 to USB converter cable.
  4. Connect the micro (smaller) end of the USB cable to the USB connector on the EK-TM4C1294XL board. Then, connect the other end of the USB cable to a free USB port on the PC. This will power-up the board.
