To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
SP-12HD away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).

5 Installing the SP-12HD HD-SDI Processor in a Rack
This section describes how to install the SP-12HD in a rack.
Before Installing in a rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range: To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace hose screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
•In some models, the front panel
may feature built-in rack ears
•Detachable rack ears can be
removed for desktop use
•Always mount the machine in the
rack before you attach any cables
or connect he machine to the
power
•If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5°to +45°C (41°to 113°F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20°to +70°C (-4°to 158°F)
Storage humidity range 5 to 95% RHL, non-condensing
!
CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with he machine.

6 Connecting the SP-12HD HD-SDI Processor
You can use your SP-12HD to convert1composite video, s-Video,
component video (YUV), or SDI signals to composite video (PAL or
NTSC), s-Video, component video (YUV) and2
Figure 2
SDI, as well as to a
“Before/after” split-screen, as the example illustrates in .
To connect3the SP-12HD Digital Video Processor, do the following4
1. Connect the following sources to the SP-12HD:
:
•The composite video source (for example, a DVD player)
to the CV INPUT BNC connector
•The s-Video source (for example, an S-VHS player) to the
Y/C INPUT 4-pin connector
•The SDI source (for example, a digital video player) to the
SDI INPUT BNC connector
2. Connect the component video INPUTS BNC connectors, Y, B-Y, and
R-Y to YUV video source.
3. Connect the following acceptors to the SP-12HD:
•The SPLITTER OUTPUT BNC connector to the split
image acceptor (for example, a display)
•The Y/C OUTPUT 4-pin connector to an s-Video acceptor
(for example, a display)
•The CV OUTPUT BNC connector to a composite video
acceptor (for example, a display)
•The BNC OUTPUTS connectors: Y, B-Y and R-Y to a
video acceptor (for example, a plasma display)
•The two SDI OUTPUTS BNC connectors to two serial
digital video acceptors (for example, two monitors: SDI 1
and SDI 2)
4. Connect a PC or other controller, if required (see section 6.1).
5. Set the DIP-switches (see section 6.2).
6. Connect the AC power cord.
1 The SP-12HD does not perform standard conversion or scaling The output resolution is always identical to the input
resolution
2 All output formats are always available when the format is valid for the input resolution being used
3 When only one output is required, connect that output of the SP-12HD, and leave the other outputs unconnected
4 Switch OFF the power on each device before connecting it to your SP-12HD After connecting your SP-12HD, switch on
its power and then switch on the power on each device

7 Operating the SP-12HD HD-SDI Processor
Operate your SP-12HD via:
•The front panel buttons
•RS-232 serial commands transmitted by a touch screen system,
PC, or other serial controller
To operate the SP-12HD using the front panel buttons, do the following:
1. Turn on the power and press the INPUT button to select the source to
convert: CV, YC, YUV or SDI.
The appropriate INPUT LED lights (indicating selection of that source).
2. Press the AUTO button to select input standard that cycles as follows:
AUTO, 480i/60, 480p/60, 576i/50, 576p/50, 720p/50, 720p/59.94, 720p/60,
1080i/50, 1080i/59.94, 1080i/60, 1080p/23.98, 1080p/24, 1080p/25,
1080p/29.97, 1080p/30, 1080psf/23.98, 1080psf/24, 1080psf/25,
1080psf/29.97 and 1080psf/30.
With a CVBS or Y/C input source, the cycling sequence is reduced to three
modes: AUTO, 480i/60 and 576i/50. The appropriate 1/1.001 LED, one
SCANNING FORMAT LED, one FIELD/FRAME RATE LED and one
ACTIVE LINES PER FRAME LED lights. If the AUTO button does not
illuminate, it means a forced input standard. Otherwise, the AUTO button
illuminates, lighting LEDs to indicate the detected input standard.
3. Adjust the color, brightness, contrast, hue, sharpness1, H-shift, V-shift2

9 Communication Protocol
RS-232 communication between the SP-12HD and the PC is performed
using this protocol (VER 0.1). The protocol1
The controller and the machine should be connected via a null-modem
connection, that is, if using a 9-pin D-sub port, connect pin 5 of the PC to
pin 5 of the machine, cross pins 2 and 3, that is, connect pin 2 of the PC to
pin 3 of the machine, and connect pin 3 of the PC to pin 2 of the machine.
On the PC side, short pins 4 and 6, and short pins 1, 7 and 8.

1 This protocol complements Kramer’s “Protocol 2000” (Kramer’s switcher protocol), that is, the two protocols can co-exist
without disturbing one another (according to Protocol 2000’s definitions, the SP-12HD would be machine number 24)

DESCRIPTION OF INSTRUCTIONS
Inst
No Instruction name Data Number Data Name Extended Notes
0 RESET 0 Initialize machine 0 When the machine is initialized, it sends the
RESET code (DATA = 0) If the machine receives
this code, it resets to its “power-up” state
1 Configure the
machine to its
factory default
state
0 When the machine receives this code, all
programmable parameters are reset to their factory-
default values
16 ERROR If the machine receives an invalid instruction, it
replies by sending this error code

33 WRITE FRONT-
PANEL SWITCH
DATA
Front panel
switch number*Front panel switch value* The PC sends a value directly to the machine If valid, the machine implements this new value, and
replies by sending the same data back to the PC
Note that the addressed front-panel switch does not
need to be pressed in order to change its value via
RS-232
If the “+” or “-” button is pressed on the machine,
resulting in a change in a switch value, then this
switch number and value is sent to the PC

35 STORE 0 0–15 Program
number Program 0 = Setup 1 Program 15 = Setup 16
61 IDENTIFY
MACHINE 3 Request software version number 0 If the software version is requested, the machine replies with DATA as the version number before
the decimal point, and EXTENDED DATA is the
value following the decimal point For example, for
version 3 4, the machine replies with DATA = 03
(hex), and EXTENDED DATA = 04 (hex)
