Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Getting Started 2 KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview 3 Overview The VP-81KSi routes any input to both outputs, using 15-pin HD female connectors for the computer graphics video signals, a 3.5mm mini jack for the unbalanced stereo audio Output 1 signal, and a detachable terminal block connector for the balanced stereo audio Output 2 signal.
Overview 3.1 Defining EDID The Extended Display Identification Data (EDID 1) is a data-structure, provided by a display that describes its capabilities to a graphics card (that is connected to the display’s source). The EDID enables the PC or laptop to “know” what kind of monitor is connected to the output. The EDID includes the manufacturer’s name, product type, timing data supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.
Defining the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 4 Defining the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher Figure 1 and Table 1 define the front panel of the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher.
Defining the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher Figure 2 and Table 2 define the rear panel of the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher.

Defining the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 4.1 Using the IR Transmitter for the VP-81KSi You can use the RC-IR3 IR transmitter to operate the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver 1. The external IR receiver can be located 15m (49ft) away from the machine.
Installing in a Rack 5 Installing in a Rack This section describes the preparation and installation of the unit in a rack. .
Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 6 Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher Figure 3: Connecting the VP-81KSi To connect 1 the VP-81KSi, as illustrated in the example in Figure 3: 1. Connect up to eight 2 SI-1VGA Remote Step-in Panels to the VP-81KSi 15-pin HD VIDEO INPUT connectors 3 and to the 3.5mm mini jacks (from 1 to 8). 2. Connect up to eight WUXGA computer graphics sources to the SI-1VGA 15-pin HD video connectors. 3.
Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 5. Connect the RJ-45 AV ON CAT 5 output connector to a compatible TP receiver (for example, TP-120). 6. Connect the unbalanced audio 3.5mm AUDIO OUTPUT jack to an unbalanced audio acceptor (for example, power amplifier). 7. Connect the balanced audio 5-pin terminal block (see Section 6.1) to an audio acceptor 1. 8. Connect up to eight remote, contact closure input selection switches to the REMOTE terminal block (see Section 6.2). 9.
Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 6.2 Connecting Remote Contact Closure Input Selection Switches You can connect remote input selection switches to the Remote terminal block on the rear panel of the VP-81KSi which enables you to remotely activate the relevant input. The following example (see Figure 6) illustrates three switches (A, B and C) connected to remotely controlled inputs 1, 2 and 3 respectively (up to eight switches can be connected).
Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 2. Using a 15-pin HD (male to male) cable 1, connect the 15-pin HD connector on the rear of the SI-1VGA to the corresponding input on the rear of the VP-81KSi. 3. Using an audio cable with 3.5mm mini jacks at both ends 2, connect the 3.5mm mini connector on the rear of the SI-1VGA to the corresponding audio input on the rear of the VP-81KSi. 4. Repeat steps 2 and 3 for each SI-1VGA remote step-in module. Figure 7: Connecting the SI-1VGA 6.
Connecting the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher 6.6 Connecting to the VP-81KSi via the RS-485 Port You can operate the VP-81KSi via the RS-485 port from a distance of up to 1200m (3900ft) using any device equipped with an RS-485 port (for example, a PC). For successful communication, you must set the RS-485 machine number and bus termination.

Kramer Protocol Note: Before sending any of the codes in Table 13, the command 2A 86 80 81 must be sent.
Kramer Protocol 17.1 Switching Protocols You can switch protocols either via the front panel buttons (see Section 17.1.1) or the protocol commands (see Section 17.1.2). 17.1.
Kramer Protocol # Address@ Command_1 Parameter1_1,Parameter1_2,… |Command_2 Parameter2_1,Parameter2_2,… |Command_3 Parameter3_1,Parameter3_2,… |…CR Device message format: Start ~ Address (optional) Body message Sender_id@ Delimiter CR LF Device long response (Echoing command): Start ~ Address (optional) Sender_id@ Body command SP [param1 ,param2 result Delimiter …] CR L F CR = Carriage return (ASCII 13 = 0x0D) LF = Line feed (ASCII 10 = 0x0A) SP = Space (ASCII 32 = 0x20) 17.2.
Kramer Protocol Commands entering: If terminal software used to connect over serial \ ethernet \ USB port, that possible to directly enter all commands characters (CR will be entered by Enter key, that key send also LF, but this char will be ignored by commands parser). Sending commands from some controllers (like Crestron) require coding some characters in special form (like \X##). Anyway, there is a way to enter all ASCII characters, so it is possible to send all commands also from controller.
Kramer Protocol Command Switch audio & video Switch video only Basic routing commands Syntax Response AV IN>OUT, IN>OUT, … AV IN>OUT, IN>OUT,…RESULT VID IN>OUT, IN>OUT, … Short form: V IN>OUT, IN>OUT, … VID IN>OUT, IN>OUT, …RESULT Note: When AFV mode is active, this command will switch also audio. If audio is breakaway – device display mode will change to show audio connections status.
Kramer Protocol Command Change signal status Get signal status ------------------- Signal Status commands Syntax Response SIGNAL INPUT, STATUS SIGNAL? INPUT Parameters Description: INPUT = Input number, ‘*’ for all. STATUS = Signal state: "0" or "off" for not existent signal. "1" or "on" for existent signal.

Kramer Protocol 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.
Kramer Protocol 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 VS7588YC, 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 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system.
