Overview
The high performance Kramer RC-IR2 is an upgrade of the popular RC-IR1,
with additional functionality that lets you control Kramer scalers as well as
switchers.
The RC-IR2:
Is a hand held infrared remote control transmitter1 that includes the
protocols of all Kramer devices and is programmable to control any
Kramer machine (see Figure 1)
Transmits to a compatible remote receiver, either built-in (see Figure 2) orexternal (see Figure 3). The transmitter includes non-volatile memory thatretains the last setting, even after the power supply is interrupted
To achieve the best performance:
Point the remote control transmitter directly at the remote receiver(whether built-in or external)
Make sure that nothing blocks the path of the infrared beam2
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer RC-IR2
away from moisture, excessive sunlight and dust

1 Delivers instantaneous results and has a range of up to 15 meters
2 For example, do not place a group of switchers in front of the remote receiver. This may prevent it from receiving signals
from the remote control transmitter

5Your Remote ReceiverThis section includes details of:
The built-in front panel remote receiver (see section 5.1)
How to connect the external remote receiver (see section 5.2)

5.1 Identifying the Built-in Infrared Receiver
Most Kramer switchers1 include a built-in front panel remote receiver that is
located to the left of the power switch, as Figure 2 illustrates:

IR Receiver
LED
Figure 2: Built-in Remote Receiver

5.2 Connecting the External Infrared Receiver
When your RS-232 controlled Kramer switcher has no built-in front panel
remote receiver, you can use the external remote receiver1 (see Figure 3). The
external remote receiver includes an attached RS-232 cable with a 9-pin D-sub
connector, and a 12V DC power socket.
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

1 Some switchers do not have a built-in remote receiver. For these units, an external remote receiver may be connected to theswitcher. When ordering an RC-IR2 remote control transmitter, a separate order must be made for an external remote receiver
2 For example: model number AD2512C, part number 2535-000251

5

Your Remote Receiver

To connect the external remote receiver, as the example in Figure 3 illustrates,
do the following:
1. Connect the external remote receiver to the RS-232 port on the Kramer
switcher, via one of the following methods:
A direct one-to-one connection, by simply connecting the attached
RS-232 cable’s 9-pin D-sub connector to the RS-232 9-pin D-sub
port on the switcher
An extended (up to about 25 meters) one-to-one connection, byconnecting a flat cable, or by just connecting PIN # 2 to PIN # 2, PIN# 3 to PIN # 3, and PIN # 5 to PIN # 5 (ground) between the attached
RS-232 cable’s 9-pin D-sub connector and the RS-232 9-pin D-sub
port on the switcher
A cross connection (or Null-modem adapter) when required. For the
cross connection, connect PIN # 2 to PIN # 3, PIN # 3 to PIN # 2,
and PIN # 5 to PIN # 5
2. Connect the 12V DC power adapter to the power socket and connect the adapter
to the mains electricity.

Connect to the
RS-232 Port on
the Kramer Switcher

5.3 Using the RC-IR2 Remote Control Transmitter
The RC-IR2 Remote Control Transmitter includes three types of keys: theGeneral keys1, the ROUTER2 keys and the SCALER keys.
The following sections describe how to use the:General keys (see section 6)
ROUTER keys (see section 7)
SCALER keys (see section 8)
By design, every keypad operation is subject to a 10 second timeout. Failure
to fully execute an action within 10 seconds will necessitate restarting that
action.

6

The General (Gray) Keys
The RC-IR2 includes a power ON button, a red transmission LED, which
illuminates when pressing any key, as well as:
Selector buttons, which operate differently for the ROUTER mode and the
SCALER mode (see section 7 and section 8 respectively)
A LOCK button, for locking the front panel, andVOL- and VOL+ buttons for decreasing or increasing the volume level
respectively3

1 Which are applied in the ROUTER mode as well as in the SCALER Mode
2 For controlling switchers
3 For the volume adjustment in scalers, see section 8.1. For the volume adjustment in the VP-23N and VP-23RC, see section
7.4.1.2

The Router Mode Keys
This section describes how to:
Configure the RC-IR2 (see section 7.1)
Initialize the RC-IR2 (see section 7.2)
Use the ROUTER Mode keys (see section 7.3)

7.1 Configuration
For the RC-IR2 to identify the switcher that it has to control, a ROUTER
number (see section 7.2.1) and a GROUP number1 (see section 7.2.2) need to be
assigned for specific identification of each switcher.
Older Kramer products were arranged in several groups according to several
criteria, such as the protocol type and version, the baud rate, the number ofunits that can be controlled per group and so on, as defined in Table 3, whichapplies to older Kramer machines.
Table 3 defines 16 different groups, numbered 1, 2, 3, 4, 5, 6, 7, 9, 10, 12, 14, 15,
16, 17, 18, and 20 (there are no groups numbered 8, 13, or 19). Groups numbered
1, 2, 3, 4, 14, 15 and 16 include units with only a single output. In some cases, youwill need to allocate different versions of the same unit to different groups. For
example, the VS-4x4YC vertical interval matrix switcher appears in Groups 5 and12. Group 5 works with the old protocol (at the time that the VS-4x4YC was
initially manufactured) and Group 12 works with the new protocol2.
Newer Kramer products are allocated to either group 12 (communication
3
protocol 2000) or group 11 (if they have one output only ).

1 In cases where the machine does not have a built-in IR receiver it still has to be allocated to a group and can be controlled
via the external IR receiver (see section 5.2)
2 Kramer Protocol-2000 (version 3.1 or higher)
3 The group 11 machines are protocol 2000 switchers that have only one output, so that the output is preset to 1 and you only
have to press the input number digit on the selector buttons
