Atomic IMU 6DOF, SEN-09184

I hace a Atomic IMU 6DOF, SEN-09184 connected with Xb24 and XBee Explorer USB (WRL-08687) connected with Xb24.

I have X-CTU sofeware and use “Remote Configuration” to config ( Network & security, RF interface, Serial interface…). Then i use Range Test in X-CTU and try to sent data from XBee Explorer USB to SEN-09184 but SEN-09184 can’t reveive it.

In the similar way, if i replace SEN-09184 by XBee Explorer Serial (WRL-09111) eveything is ok

Please help me to make it throught.

Thanks and waitting for your replay!!!
