56Khz sensor and non 56Khz unit

Hey
I have a unit that requires the 56Khz (expressvu) and one that does not (Viewsat 2000 Platnium).
Am I correct in assuming I can use this setup because the 56khz is for receive only?
Any tips would be appreciated. Having trouble getting the USB-UIRT to change the channels on my Viewsat.
Thanks!
Brad
