You are not misunderstanding! Remote shutter release on the K-3 is available through either an IR signal (front or rear IR sensors) or the cable release fitting at right rear. Neither the hot shoe nor the PC port are capable of triggering the shutter...flash stuff only for those two. This is typical for Pentax cameras having those features. With the PW PlusX you will require the optional CM-C3-ACC cable:

This cable is listed for various Canon models, but is compatible with Pentax too.
