Will a 5530 scan card work in a Falcon 2? Thanks.

I've said it before, but I'll say it again:

Yes - ALL NS-30's are cross compatible.

Here is a list of models that I know of that all use the same scan system:

TA-181
TA-221
KM-1650
KM-2050
KM-2550
KM-3035
KM-4035
KM-5035
KM-4530
KM-5530
KM-6330
KM-7530
KM-6030
KM-8030
KM-C2520
KM-C2525E
KM-C3225
KM-C3232E
KM-C4035E

Furthermore, Falcon I (KM-2530/KM-3530 & KM-4030) scan systems can be used in the above listed models. To use a Scan System 'F'(B) in the Falcon I series you must also have an additional proprietary module.

I believe the KM-620 and KM-820 also use the same scan system but I haven't had to figure that one out yet. Can anyone confirm this?

Also - if I've left out any models please let me know.

Thanks Scotty, that's what I needed to know. Good info BTW.

Also of note: The cheapest currently available scan system is the Scan F(B).
