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 RC-53DLC 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.
There are no operator serviceable parts inside the unit
Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Disconnect the power and unplug the unit from the wall
before installing
2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country
go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

Light green, indicating volume level
Rotate clockwise to increase volume level
Slide downwards (in the direction of the arrow) for K-NET
termination, slide upwards to leave bus un-terminated.
The last physical device on a K-NET bus must be terminated
You can access the switch by removing the volume control knob, and
unscrewing the 4 screws on the front panel
By the system integrator only

Figure 2 and Table 2 define the RC-53DLC rear panel.

Connect to a computer for firmware upgrade1
Connect to grounding wire (see Section 4.3)
Connect the GND to the Ground connection2, connect B (-) and
A (+) to RS-485, and connect +12V to +12V on the companion
unit
For technical support use only (should be set to the left in the
direction of the arrow for normal operation)
When the unit is connected via K-NET to a Master Room Controller, you can upgrade the firmware via the USB or ETH ports of the
Master Room Controller

4.3 Grounding the RC-53DLC
The grounding screw is used to earth the chassis of the unit to the building ground
preventing static electricity from impacting the performance of the unit.
Figure 5 and Table 5 define the grounding screw components.
Figure 5: Grounding Connection
Components
Table 5: Grounding Component
Descriptions
To ground the RC-53DLC:
1. Connect the Ring Tongue terminal to the building grounding point wire (it is
recommended to use a green-yellow AWG#18 (0.82mm2) wire, crimped with
a proper hand-tool).
2. Insert the M3x6 screw through the toothed lock washers and the tongue
terminal in the order shown above.
3. Insert the M3x6 screw (with the two toothed lock washers and ring tongue
terminal) into the grounding screw hole and tighten the screw.

Using the RC-53DLC K-NET™ Auxiliary Control Panel
5 Using the RC-53DLC K-NET™ Auxiliary Control Panel
The installation process is not detailed in this user manual. This user manual is
applicable once the unit is installed and configured1, and includes:
Setting up the labels on the buttons, according to your specific requirements
Configuration of the Master room controller via the K-Config Windows®-
based configuration software
Since the auxiliary panel is used as a remote controller for Master Room
Controllers via the proprietary communication channel K-NET (as illustrated in
Figure 6):
It requires only a K-NET connection to the Master Room controller
A power supply unit is not required2
The auxiliary panel can be programmed only via the Master Room controller
(for example, the Kramer SV-551 SummitView™ Processor/Switcher)
Figure 6: RC-53DLC connected to the SV-551 SummitView™ Processor / Switcher
By authorized Kramer technical personnel or by an external system integrator
Power supplies are sold separately. Consult your Kramer dealer for details
