With the older TCU combo, SR5068 and TAS5048, all three program with send the RF through the same P2 port on the TAS5048. However, with the new SR8048 and SR8068 combo, TASKIT C2 and Testdrive EVDO still send signal through the same port (P2 on the SR8048), but TASKIT PLTS uses the P1 port on the SR8048. Therefore, if the UE is connected to the P2 port of the SR8048, it will not see a signal. Use the P1 port instead.
