Overview  
3 Overview  
The Kramer VP-411DS is a high performance 4x1 automatic switcher for  
UXGA signals and stereo audio signals. It switches any one of four UXGA  
sources to the UXGA output 15-pin HD computer graphics video connector,  
and any one of four stereo audio sources to the stereo audio output on a 3.5mm  
mini jack. Both the UXGA and audio IN 1 connectors are connected to output  
loop connectors.  
The VP-411DS can be configured to operate in the automatic standby  
switching mode or in the manual mode, via the dipswitches. When in the  
automatic mode, the VP-411DS will switch to the primary input when it is  
present. It will switch to the second input in priority upon loss of the primary  
input1 and it will switch from the secondary input back to the primary input  
when the primary signal is reconnected. When in the manual mode, the  
VP-411DS is controlled by the control panel.  
In addition, the VP-411DS:  
ñ
With its video bandwidth exceeding 300MHz, ensures transparent operation  
at the highest resolutions  
ñ
Includes the Kramer innovative integrated sync processing: KR - ISP™  
technology, which lets you achieve a sharp, stable image when the sync  
level is too low, by restoring the sync signal waveform  
ñ
ñ
Has PANEL LOCK and OFF buttons  
Automatically switches the stereo audio signal with the video signal (audio-  
follow-video) when switching the active input to the output  
ñ
Includes PRIORITY dipswitches for selecting the default UXGA master  
source signal  
ñ
ñ
Comes with contact closure remote control for forced operation  
Is housed in a desktop-sized enclosure, and is 12VDC fed

4.1 Using the IR Transmitter  
You can use the RC-IR2 IR transmitter to control the machine via the built-in  
IR receiver on the front panel or, instead, via an optional external IR receiver2.  
The external IR receiver can be located 15 meters away from the machine. This  
distance can be extended to up to 60 meters when used with three extension  
cables3.  
Before using the external IR receiver, be sure to arrange for your Kramer dealer  
to insert the internal IR connection cable4 with the 3.5mm connector that fits  
into the REMOTE IR opening on the rear panel.  
Connect the external IR receiver to the REMOTE IR 3.5mm connector.

When all the dipswitches are set to OFF, switching is manual and the inputs are  
switched to the output via the front panel INPUT SELECTOR buttons.  
The priority is always set from the lowest number to the highest. For example,  
if input 2 is set to be the primary input (DIP 2 is set to ON and DIPs 1, 3 and 4  
are set to OFF), the secondary input is IN 3. IN 4 is the third in the sequence,  
and IN 1 will be last in priority. In this case, if the signal on IN 2 is cut off, the  
switcher automatically switches IN 3 to the output, and if that is also  
disconnected, IN 4 is automatically switched to the output (followed by IN 1, if  
necessary). If, in the meantime, the IN 2 signal is restored, IN 2 will take  
priority once again.

Kramer Protocol 2000  
9 Kramer Protocol 20001  
The VP-411DS is compatible with Kramer’s Protocol 2000 (version 0.50)  
(below). This RS-232/RS-485 communication protocol uses four bytes of  
information as defined below. For RS-232, a null-modem connection between  
the machine and controller is used. The default data rate is 9600 baud, with no  
parity, 8 data bits and 1 stop bit.  
Note: compatible with Kramer’s Protocol 2000 does not imply that a machine  
includes all of the commands below. Each machine uses a sub-set of Protocol  
2000, according to its needs.

D – “DESTINATION” :  
Bit 7 – Defined as 0.  
0 - for sending information to the switchers (from the PC);  
1 - for sending to the PC (from the switcher).  
N5…N0 – “ INSTRUCTION”  
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is  
performed via the machine’s keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The  
instruction codes are defined according to the table below (INSTRUCTION NO. is the value to be set for N5…N0).  
2nd BYTE:  
Bit 7 – Defined as 1.  
I6…I0 – “ INPUT”.  
When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched.  
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was  
switched. For other operations, these bits are defined according to the table.  
3rd BYTE:  
Bit 7 – Defined as 1.  
O6…O0 – “OUTPUT”.  
When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched.  
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was  
switched. For other operations, these bits are defined according to the table.

Kramer Protocol 2000  
4th BYTE: Bit 7 – Defined as 1.  
Bit 5 – Don’t care.  
OVR – Machine number override.  
M4…M0 – MACHINE NUMBER.  
Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial  
port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then  
all machine numbers will accept (implement) the command, and the addressed machine will reply.  
For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is  
configured as MACHINE NUMBER = 1.

NOTES on the above table:  
NOTE 1 - When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to  
the switchers, it will reset according to the present power-down settings.  
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if  
the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the  
HEX code  
01  
85  
88  
83  
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output 7  
via the front panel keypad, then the switcher will send HEX codes:  
41  
81  
87  
83  
to the PC.  
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by  
sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high).  
NOTE 3 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are  
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per  
the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is breakaway  
setting, then the reply to the HEX code  
0B  
would be HEX codes  
4B 80  
80  
80  
85  
81  
85  
NOTE 4 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter  
associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an  
input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent  
while the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.  
17  
 
Kramer Protocol 2000  
NOTE 5 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1 the  
machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to  
the request to send the audio machine name would be (HEX codes):  
7D  
96  
90  
81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).  
If the request for identification is sent with the INPUT set as 3 the appropriate machine will send its software version number.  
Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in front of the  
decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the request to send  
the version number would be (HEX codes):  
7D  
83  
85  
81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).  
If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for the  
VS-7588YC, the reply to the request to send the first suffix would be (HEX codes):  
7D  
D9  
C3  
81 (i.e. 128dec+ ASCII for “Y” ; 128dec+ ASCII for “C”).  
NOTE 6 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system. For  
example, if six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code  
3E  
82  
81  
82 (ie. request the number of outputs)  
would be HEX codes  
7E  
82  
90  
82  
ie. 16 outputs  
NOTE 7 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 3 above, except that here the  
OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.
