STEPS

Overview

The Kramer VP-411DS is a high-performance 4×1 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 connector. Both the UXGA and audio IN 1 connector 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 DIP switches. When in 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 manual mode, the VP-411DS is controlled by the control panel.

In addition, the VP-411DS:

With its video bandwidth exceeding 300MHz, ensures transparent operation at the highest resolutions
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
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
Includes PRIORITY DIP-switches for selecting the default UXGA master source signal
Comes with a contact closure remote control for forced operation
Is housed in a desktop-sized enclosure, and is +12V DC fed

The VP-411DS can be controlled via the:

Front panel buttons
Infrared remote control transmitter or external remote IR receiver extension cable
RS-232 serial commands transmitted by a touch screen system, PC, or another serial controller
Remote control contact closure

To achieve the best performance:

Connect only good-quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low-quality cables)
Avoid interference from neighboring electrical appliances that may adversely influence the signal quality and position your Kramer VP-411DS away from moisture, excessive sunlight, and dust

Caution – No operator-serviceable parts inside the unit.
Warning – Use only the Kramer Electronics input power wall adapter that is provided with this unit1.
Warning – Disconnect power and unplug the unit from the wall before installing or removing the device or servicing unit.

Using the IR Transmitter

You can use the RC-IR3 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 9F REMOTE IR opening on the rear panel. Connect the external IR receiver to the REMOTE IR 3.5mm connector.

By default, both switches are set to NORMAL

Setting the PRIORITY DIP-switches

Figure 4 and Table 3 describe the VP-411DS unit DIP-switches and the priority setup respectively.

Figure 4: VP-411DS DIP-switches
Table 3: DIP-switch Priority Setup

	DIP-switch Position
Priority sequence	1
Manual operation	OFF
1, 2, 3, 4	ON
2, 3, 4, 1	OFF
3, 4, 1, 2	OFF
4, 1, 2, 3	OFF

When all the DIP-switches 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-switch 2 is set to ON and DIP- switches 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.

When sending a serial switching command while the VP-411DS is in Priority Mode, the VP-411DS checks for an active signal on the selected input for a user-defined period of time (the default is 30 seconds). Once an active signal is detected, the selected input will be switched to the output. If no active signal is detected during the set time period, the previously selected input will remain switched to the output according to the priority setup, and the VP-411DS will send an appropriate RS-232 command to indicate its current switching status or an “all inputs invalid” command if there is no valid input.

Connecting the REMOTE Terminal Block

The contact closure remote control pins operate in a similar way to the INPUT selector button. Using the contact closure remote control you can select the UXGA input or cut off the inputs. To do so, temporarily connect the required input1 pin on the REMOTE terminal block to the GND (Ground) pin, as Figure 5 illustrates.

DO NOT connect more than one pin to the GND pin at the same time

Kramer Protocol 2000

The VP-411DS is compatible with Kramer’s Protocol1 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.

Table 6: Protocol Definitions

MSB LSB

	DESTI- NATION	INSTRUCTION
0	D	N5
7	6	5

1st byte

	INPUT
1	I6
7	6

2nd byte

	OUTPUT
1	O6
7	6

3rd byte

	MACHINE NUMBER
1	OVR
7	6

4th byte

1st BYTE: Bit 7 – Defined as 0.
D – “DESTINATION”: 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.

1 You can download our user-friendly “Software for Calculating Hex Codes for Protocol 2000” from the technical support section on our Web site at http://www.kramerelectronics.com

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.

Table 7: Instruction Codes for Protocol 2000

Note: All values in the table are decimal, unless otherwise stated.

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 80 80 85 would be HEX codes: 4B 80 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.
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.
NOTE 8 – The reply to the request is as follows: the same INSTRUCTION and INPUT codes as were sent are returned and the OUTPUT is assigned with the value 0 if no valid input is detected; or 1 if valid input is detected.
NOTE 9 – 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.
NOTE 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever the unit detects a change in the state of an input (in real-time). For example, if input 3 is detected as invalid, the unit will send the HEX codes: 10 83 84 81 If input 7 is detected as valid, then the unit will send HEX codes: 10 87 85 81.
NOTE 28 – In the automatic priority switch mode, in the case where the user tries to switch manually, and there is no valid input the unit will wait the number of seconds configured by this command until the input becomes valid and then execute the switching. If during this delay the input remains invalid the switching will not execute.
