ST-2U-U Option

Introduction
The NTI ST-2U-U UNIVERSAL KVM Switch has 2 additional female USB type B ports that allow USB compatible CPUs (SUN, MAC, or
WINxx) to be connected to the switch.
General Notes
The ST-2U-U should have all cables attached before powering up. If no cable is plugged into either of the 8 pin miniDIN CPU ports
labeled DEV 1 or DEV 2 (see Fig. 15) on the ST-2U-U, then their respective USB ports labeled for DEV1 USB and DEV 2 USB on the ST-
2U-U will become the default active CPU port(s).
The USB ports on the ST-2U-U are HOT PLUGGABLE.
The 8 pin miniDIN cables are not HOT PLUGGABLE. They must be plugged in at power up to operate correctly.
