How to send frames without the PANID broadcast enabled when linking from Xbee S1 to Microchip MRF24J40?

Hello, I can send frames no problem when I enable the PANID broadcast between xbee pro series 1 and microchip’s MRF24J40 radio. However, I want to be able to send frames between PANIDs without enabling broadcast. I am using the 802.15.4 protocol in 16-bit address mode. Thanks!
