The table below details the function of each component.

Figure 2: VS-42HN 4x2 HDMI Matrix Switcher Rear Panel

This diagram illustrates the rear panel of the VS-42HN. It includes IN HDMI Connectors (10, 1 to 4), OUT HDMI Connectors (11, 1 to 2), an RS-232 9-pin D-sub Serial Port Connector (12), an ETHERNET RJ-45 Connector (13), a RESET Button (14), a REMOTE IR Opening (15), and a Mains Power Connector, Fuse and Power Switch (16). The table below details the function of each component.

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 receiver (Model: C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables (Model: C-A35M/A35F-50).

Before using the external IR receiver, be sure to arrange for your Kramer dealer to insert the internal IR connection cable (for example, P/N: 505-70434010-S) 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.

Installing in a Rack

This section provides instructions for rack mounting the unit.

Before installing in a rack, be sure that the environment is within the recommended range:

[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 the machine.

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 those 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:

• 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 the 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 available from our Web site.

Connecting the VS-42HN 4x2 HDMI Matrix Switcher

Two HDMI displays (labeled LCD TV with Built-in Speakers 1 and LCD TV with Built-in Speakers 2) are connected to the output ports of the VS-42HN via HDMI cables. An RS-232 cable connects a PC to the RS-232 port on the VS-42HN for control.

Operating the VS-42HN 4x2 HDMI Matrix Switcher

This section describes:

• Acquiring the EDID (see Section 6.1)
• Resetting to the default EDID (see Section 6.2)
• Storing and recalling switch settings (see Section 6.3)
• Switching Between Protocol 2000 and Protocol 3000 (see Section 6.4)
• Connecting to the VS-42HN via RS-232 (see Section 6.5)
• Connecting to the VS-42HN via Ethernet (see Section 6.6)
• Upgrading the firmware (see Section 6.6.1)

6.1 Acquiring the EDID

You can acquire the EDID from OUT 1 and/or OUT 2 and copy it to any of the four inputs, or reset to the default EDID. The EDID is acquired at once for all the inputs, according to the status of the selector buttons.

To acquire or change the EDID of one or both new output displays:

1. Connect the required acceptor to the output from which you want to acquire the EDID.
2. Connect the power supply.
3. Press the EDID button and hold it for 3 seconds. The four buttons that switch to the output from which you are acquiring the EDID show their current state:

• Input buttons that do not illuminate, store the default EDID.
• Input buttons that flash store the previously acquired EDID from the OUT 1 or OUT 2 acceptor.

4. For each input, select the output from which it will acquire the EDID, or deselect it so it will reset to the default EDID value. For example, to copy the EDID of output 2 to input 3, press the INPUT SELECTOR button 3 on the TO OUTPUT 2 line.

5. Press the LOCK button. The LOCK button and the INPUT buttons flash until the EDID is acquired.

6.2 Resetting to the Default EDID

To reset to the default EDID do either of the following:

• Disconnect the outputs and repeat the steps listed in Section 6.1.
• Press the input where the default EDID is to be stored to disconnect it from the output.

6.3 Storing and Recalling a Switching Setting

You can use the STO and RCL buttons to store the current setup and then recall it.

[info] The VS-42HN stores only one setting in memory. Storing a new setting overwrites the previous one.

To store a setting:

1. Press the STO button. The STO button illuminates and the:

• Currently selected input buttons illuminate.
• The selected Input buttons in the current configuration flash.

For example, if both outputs are currently disconnected, both OFF buttons will be illuminated and the current setting input buttons (for example, INPUT 1 to OUTPUT 1 and INPUT 3 to OUTPUT 2) flash.

2. Set the machine to the desired setting. For example, press INPUT SELECTOR button 3 on the TO OUTPUT 1 line and INPUT SELECTOR button 1 on the TO OUTPUT 2 line. These buttons flash.

3. Press the STO button again to store the current setup (you have to press the STO button within 10 seconds, before the store operation times-out). The STO button no longer illuminates and the current setting is stored in the non-volatile memory.

To recall a setup:

1. Press the RCL button. The RCL button illuminates as well as the current setting input buttons, and the input buttons of the stored setup flash.
2. Press the RCL button once again to recall the stored setting.

6.4 Switching Between Protocol 2000 and Protocol 3000

To switch from Protocol 2000 to Protocol 3000 and back again using the front panel buttons:

1. On the TO OUTPUT 1 row, press input buttons 1 and 3 at the same time. Protocol 3000 is active.
2. On the TO OUTPUT 1 row, press input buttons 1 and 2 at the same time. Protocol 2000 is active.

Kramer Protocol 2000

The Kramer Protocol 2-000 RS-232/RS-485 communication uses four bytes of information as defined below. All the values in the table are decimal, unless otherwise stated.

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.

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 accept (implement) the command, and the addressed machine replies. 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.

Instruction Codes for Protocol 2000

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 resets according to the present power-down settings.

NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it performs 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) switches input 5 to output 8. If the user switched input 1 to output 7 via the front panel keypad, then the switcher sends 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 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e. those used for Store and Recall).

NOTE 4 - 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 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not defined / no valid input is detected; or 1 if it is defined / valid input is detected.

NOTE 13 - 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, 2, 5 or 7, the machine sends 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 or 4, the appropriate machine sends 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 14 - 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 15 - When the OVR bit (4th byte) is set, then the "video" commands have universal meaning. For example, instruction 1 (SWITCH VIDEO) causes all units (including audio, data, etc.) to switch. Similarly, if a machine is in "FOLLOW" mode, it performs any "video" instruction.

NOTE 16 - The reply to the "REQUEST WHETHER PANEL IS LOCKED" is as in NOTE 4 above, except that here the OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 19 - After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte. The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.

Protocol 3000

By default, the VS-42HN is set to Protocol 2000 (see Section 10) but is also compatible with Kramer's protocol 3000.

[info] Note that the VS-42HN needs to be set to protocol 2000 in order to use the IR remote control.

The VS-42HN can be operated using serial commands from a PC, remote controller or touch screen using the Kramer Protocol 3000.

This section describes:

• Kramer Protocol 3000 syntax (see Section 11.1).
• Kramer Protocol 3000 commands (see Section 11.2).

11.1 Kramer Protocol 3000 Syntax

11.1.1 Host Message Format

11.1.1.1 Simple Command

Command string with only one command without addressing:

11.1.1.2 Command String

Formal syntax with commands concatenation and addressing:

11.1.2 Device Message Format

11.1.2.1 Device Long Response

Echoing command:

CR = Carriage return (ASCII 13 = 0x0D)
LF = Line feed (ASCII 10 = 0x0A)
SP = Space (ASCII 32 = 0x20)

11.1.3 Command Terms

Command
A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-'). Command and parameters must be separated by at least one space.

Parameters
A sequence of alphanumeric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special characters for specific commands). Parameters are separated by commas.

Message string
Every command entered as part of a message string begins with a message starting character and ends with a message closing character.
Note: A string can contain more than one command. Commands are separated by a pipe ('|') character.

Message starting character
'#' - For host command/query
'~' - For device response

Device address (Optional, for K-NET)
K-NET Device ID followed by '@'

Query sign
'?' follows some commands to define a query request.

Message closing character
CR - For host messages; carriage return (ASCII 13)
CRLF – For device messages; carriage return (ASCII 13) + line-feed (ASCII 10)

Command chain separator character

When a message string contains more than one command, a pipe ('|') character separates each command.
Spaces between parameters or command terms are ignored.

11.1.4 Entering Commands

You can directly enter all commands using a terminal with ASCII communications software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial or Ethernet port on the Kramer device. To enter CR press the Enter key. (LF is also sent but is ignored by command parser).

For commands sent from some non-Kramer controllers like Crestron, some characters require special coding (such as, /X##). Refer to the controller manual.

11.1.5 Command Forms

Some commands have short name syntax in addition to long name syntax to allow faster typing. The response is always in long syntax.

11.1.6 Chaining Commands

Multiple commands can be chained in the same string. Each command is delimited by a pipe character ("|"). When chaining commands, enter the message starting character and the message closing character only once, at the beginning of the string and at the end.
Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.

11.1.7 Maximum String Length

64 characters

11.2 Kramer Protocol 3000 Commands
