=== J940 connector ===
This connector is used mainly to connect via RS485 (UART1) with other devices. User can use this connector to power the board with 5VDC. Use only 5V regulated DC.The IGEPv2 BOARD does not use this 9v power supply. Only on IGEPv2 revision B, the PWR_9V input is directly routed to JC01 and J971 connectors. On IGEPv2 revision C is not available.

=== J400 connector ===
J400 is used to [http://en.wikipedia.org/wiki/Jtag JTAG] (Joint Test Action Group). JTAG is a standardized serial protocol widely used in printed circuit boards. Its main functions are:

=== J970 connector ===
J970 is used to implement a keypad, it is connected to TPS65950. The keypad interface controller provides an enhanced keypad decode capability and simultaneously reduces host processor software overhead. When a key button of the keyboard matrix is pressed the corresponding row and column lines are shorted together. To allow key press detection, all input pins (KBR) are pulled up to VCC and all output pins (KBC) driven to a low level.Any action on a button generates an interrupt to the sequencer.The decoding sequence is written to allow detection of simultaneous press actions on several key buttons.
More information in [http://www.ti.com/product/tps65950 TPS65950] datasheets. TPS65950 send via I2C1 all the interrupt request.
