2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Do not secure the cables in tight bundles or roll the slack into tight coils
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer RS-232 Extender away from moisture, excessive
sunlight and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

4 Connecting the RS-232 Extender
Always switch off the power to each device before connecting it to your
RS-232 Extender. After connecting your RS-232 Extender, connect
its power and then switch on the power to each device.
Note! In the RS-232 Extender system, the CAT 5 cables carry
electrical power. Do NOT connect them to any other device. To avoid
this, we recommend that you attach the stickers provided to the ends
of the CAT 5 cable.

•Connect the local and remote RS-232 extender units to each other using a
CAT 5 cable.
•Up to 330m (1000ft), connect a power adapter to either the local or remote
RS-232 extender unit.
•For distances of more than 330m (1000ft) connect a power adapter to both
the local and remote RS- 232 extender units. Additional power adapters can
