Congratulations on purchasing your Kramer RC-5B2 and RC-5B4 dual inserts with RGB buttons,
which can be used as auxiliary controllers when connected via K-NET™ to a Master room controller
(for example, the SV-552 SummitView™ Processor / Switcher or one of the Kramer SL series
controllers).
K-NET is a proprietary Kramer protocol for communication between Kramer products.
The RC-5B2 and RC-5B4 packages include labels (P/N: 2808-300008) that are used as light
diffusers and therefore need to be inserted inside each button (even to “blank” buttons).
Defining the RC-5B2 and RC-5B4 Dual Inserts
The RC-5B2 and RC-5B4 dual inserts feature:
Front panel, RGB backlit buttons: two for the RC-5B2 and four for the RC-5B4
7 colors are available for backlit buttons (to be configured by the system integrator).
Two K-NET ports and a USB serial port for setting the K-Net ID and for firmware upgrade
The RC-5B2 and RC-5B4 do not require a separate power supply.
Mounting the Kramer Insert
To mount a Kramer insert or connector module:
1. Place the Kramer insert over the opening.
2. Insert the four screws (two on each side) to fix the Kramer insert in place, and tighten them.
Grounding the RC-5B2 and RC-5B4
The grounding screw is used to earth the chassis of the unit to the ground of the building preventing
static electricity from impacting on the performance of the unit.
To ground the RC-5B2 and RC-5B4:
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.
To install the button caps and labels:
1. Unscrew the two faceplate screws and remove the faceplate.
2. Remove the button cap.
3. Remove the required labels from the supplied button label sheet.
4. Hold the button cap so that it is oriented as shown in Figure 4 with the “wings” on the left and
right sides.
5. Insert the label inside the cap
Overview
The RC-5B2 and RC-5B4 dual inserts are auxiliary remote control panels for Master Room
Controllers for control of A/V equipment in a room.

6. Repeat for all caps.

7. Retaining the orientation, place the button caps on the
buttons of the RC-5B2 / RC-5B4.
8. Place the faceplate on the RC-5B2 / RC-5B4 so that the two
screw mounting holes are aligned.
9. Insert the two mounting screws and tighten with a
screwdriver.

SAFETY WARNING
Disconnect the unit from the power
supply before opening and servicing
The installation process is not detailed in this user manual. This user manual is applicable once the
unit is installed and configured (by authorized Kramer technical personnel or by an external system
integrator), 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 required
The auxiliary panel can be programmed only via the Master Room controller (for example, the
Kramer SV-551 SummitView™ Processor/Switcher)
