Pinout of P3 (SWD) on PCA10004 and PCA10005

[Eliot Stock]

We're going to be programming and debugging our prototype nRF51822 board using this adapter from Segger. It's the same connector as comes with the J-Link LITE in the dev kit.

What is the pinout of the P3 (SWD) port on the PCA10004 and PCA10005 boards? I know two of these are SWDIO and SWCLK and at least one must be GND, but I don't know which pins. Where to the other pins go to on the nRF51822?

Also, is this the connector I need for my board? Which spec/part number?

Thanks.

Thanks, very helpful. If I was to use pins 6, 8 and 10 as GPIO pins for debugging using LEDs on my board, would that confuse the Segger when flashing/debugging, do you think?

Thank you for the link, it recommends to use "pull-up or pull-down resistors on JTAG/SWD pins". Should I assume the adapters sold by SEGGER have built-in resistors? Because I'm making the connection manually, missing resistors could explain why my manual connection from DK to beacon kit does not work.
