Is there a way to configure the ADC of an XBee module?

I have multiple XBee s1 modules connected to a USB explorer acting as a SENDER, and a single XBee s1 module acting as the RECEIVER. The SENDER’s are all reading in both digital and analog inputs from their pins, and I wish to transmit these to the RECEIVER. All analog values are being received as 1023. I have printed the sensor values when connected through an arduino, and the values make sense, so I know it is not a sensor/wiring issue.

I am trying to determine if there are certain limitations to the ADC that can be performed with an XBee. Is there any way to get the following sensors to work in this context? Other recommendations?
