materials for possible future shipment

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.

Figure 1illustrates the RS-232 Extender connections.

•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

be ordered from Kramer.

Once connected, the RS-232 Extender system is ready to transmit RS-232

signals.
