XBee Power Light Blinking with DIO1-High

Using Arduino Networking, Protocols, and Devices

I am having a odd problem with my Xbee Link.

I have 2 Xbee Series 1 non Pro. 1 is on a a Roomba with DIO 1 is connected to a NPN transistor 2n2222a that turns on and off a 8v regulator that is connected to a camera. I have a 1.5K ohm resistor between the XBee DIO and the transistor.

When the Pin on the XBee is high to turn on the transistor, the power led will blink after awhile. It only happens with the DIO is high. I setup line passing and it does the same. When I set the base to high and the remote goes high, then after a little bit the power LED starts blinking again. While it is blinking if I power down the base it stops blinking.

The transistor is only drawing 1.6-1.7ma. When the XBee starts to blink it basically shuts down. The regulator cools off so it seems the XBee has shutdown, but I can't find a reason for it to do that. If I set the pin low on the base which sets the pin low on the remote so the LED stops blinking.

I can't find any documentation what a blinking power LED means.

Any idea's?

The XBee itself doesn't have any lights. So, if you have a flashing LED somewhere, it is not on the XBee. Where is it?

The LED is on the XBee adapter so I can use 5v power source and 5v TTL. I will post a schematic when I get back on my desktop.

Here is the schematic.
