which u mean??? very confusing ur post 

support commander mode n able to b triggered wirelessly r 2 different thgs
u nid a flash which is capable to b triggered wirelessly, then a body/flash with commander to trigger it
both D3100 n Di622 dun have commander mode
but Di622 can be triggered optically, which means trigger by pop up flash
if u dowan use pop up flash to trigger, then u have no choice but to get flash with commander mode(SB700,SB900), or body with commander mode, or Nikon SU800,
or d logical option, pocket wizards or similar wireless

OFF CAMERA FLASH For Di622

The Di622 has a special photo sensor built-in. Place the Di622 off camera and the flash will synchronize with the master flash placed on your camera. This wireless remote flash system is called slave flash technology and is often used for a creative lighting efficiency. Use the camera's built in flash, the camera manufacture's original flash or the Di622 as the master flash. Place one or more Di622 flash units away from the camera. The sensor circuitry of Di622 is compatible only with the latest pre-flash TTL system offered by Canon or Nikon The Di622 is not compatible with traditional flash systems or studio flash systems.

yes Nissin Di622 has wireless trigger, but u nid d TRIGGER to trigger it, which is wat commander mode for
but ur D3100 dun have, so cant trigger it using radio waves, only can trigger optically using pop up flash

wireless triggering have 2 main types,
1 is trigger by radio waves, which mean a body/flash/commander unit with commander mode send radio waves to trigger it
2nd is trigger by pop up flash, ur flash unit when set to optical trigger mode, it will fire flash when it detect flash of camera or other flash unit

u need to check ur camera manual on how to do it if its possible.

Ooh. I didnt know about this either. gonna try this at home later.
*i got a borrowed Di622 from a friend.

i just got to know about this too. check the manual here :

i think we need to change the mode to slave mode.

then i guess u would need to buy the su-800 commander to fire another remote flash.

Buy first la... then a few weeks later trade in and "upgrade". Keep the economy rolling
