Note that the VMX300(-E) supports up to eight auxiliaries. The actual number of auxiliaries available to you depends on the number of auxiliaries
the camera supports. If the camera has fewer than eight auxiliaries, for example six auxiliaries, then only the first six auxiliaries on the
Auxiliaries tab will work. If the camera supports more than eight auxiliaries, then you can only access the first eight auxiliaries through the
Auxiliaries tab.
Refer to the appropriate camera installation/operation manual for information on connecting auxiliaries.
