Digital Pass thru not working.

D-I/O pins not raising/lowering

I am attempting to build a star (1 center, 2+ outer) network that passes digital and analog data over the xbee pins (from outer node to center - and eventually to my Arduino which works will with direct wiring). To simplify, i have reduced to 2 nodes.

When using DOUT/IN the UART connection is working (this tested fine) however i cannot seem to affect the I/O Pins. I have upgraded to current/same firmware, and reset to factory.

Inventory and config :

2 Sparkfun Breakouts (programed via Sparkfun FTDI)

XBEE series 1 (Not pro)

You have not enabled either change detect or a sample rate on your Input module. This needs to be done for the input to sample and transmit.
