Discover Xbee Devices with ConnectPort X4

Using the ConnectPort X4 Configuration and Management, in XBee Networks,i try to discover XBee Devices (The X4 is set as a coordinator and trying to discover a XBee 232 Adapter ZB Pro S2B) but it doesn’t find the device.

Are they both Zigbee versions of the devices?

Are they both using the same scan channel mask and PAN ID?

Does the RS232 adapter report that it is associated (ATAI0)?
