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 (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 circuits). 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

Connecting the VM-24H

Always switch off the power to each device before connecting it to your VM- 24H. After connecting your VM-24H, connect its power and then switch on the power to each device
To connect the VM-24H, as illustrated in the example in Figure 3, do the following:

1. Connect the two HDMI sources, for example, a DVD player and a set top box, to the INPUT 1 and INPUT 2 connectors, respectively.
2. Connect the HDMI OUTPUT connectors to up to 4 HDMI acceptors, using Kramer HDMI copper cables. In this example, connect the:
   • OUTPUT 1 connector to acceptor 1 (for example, a plasma display)
   • OUTPUT 2 connector to acceptor 2 (for example, an LCD TV)
   • OUTPUT 3 connector to acceptor 3 (for example, an LCD TV)
   • OUTPUT 4 connector to acceptor 4 (for example, a plasma display) Up to four outputs can be connected. Not all outputs need to be connected.
3. If required, connect a PC and/or controller to the RS-232 port (see Section 6.1).
4. Connect the power cord to the mains electricity (not shown in Figure 3).
5. If required, acquire the EDID (see Section 6.3).

Operating the VM-24H

This section describes how to:

• Control the VM-24H via RS-232, see Section 6.1
• Operate the VM-24H, see Section 6.2
• Use the EDID button, see Section 6.3

Controlling via RS-232

• You can connect to the unit via a crossed RS-232 connection, using for example, a PC. A crossed cable or null-modem is required as shown in method A and B respectively. If a shielded cable is used, connect the shield to pin 5
• Method A (Figure 4) Connect the RS-232 9-pin D-sub port on the unit via a crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be connected) to the RS-232 9-pin D-sub port on the PC.
  • Note: There is no need to connect any other pins
  • Figure 4: Crossed Cable RS-232 Connection
• Hardware flow control is not required for this unit. In the rare case where a controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on the controller side.
• Method B (Figure 5) Connect the RS-232 9-pin D-sub port on the unit via a straight (flat) cable to the null-modem adapter, and connect the null-modem adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually contains all nine wires for a full connection of the D-sub connector. Because the null-modem adapter (which already includes the flow control jumpering described in Method A above) only requires pins 2, 3 and 5 to be connected, you are free to decide whether to connect only these 3 pins or all 9 pins.
  • Figure 5: Straight Cable RS-232 Connection with a Null Modem Adapter

Operating the VM-24H
To operate the VM-24H:

1. Turn ON the POWER.
2. Select the desired input.
3. If required, press the EDID button to acquire or change the EDID data (see Section 6.3).

Using the EDID Buttons
You can acquire the EDID from:

• One Output (the selected output LED flashes)
• The Default EDID (all the output LEDs flash)
• Several Connected Outputs, the Auto-mix Mode (the output LEDs flash in sequence)

The EDID acquired is a weighted average of all the connected outputs. For example, if several displays with different resolutions are connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included in the EDID. To cycle between the different modes (One Output, Default and Auto-mix), as defined in the following table, press the EDID SELECT button.

Current EDID Mode| Appearance| To cycle to the Default EDID| To cycle to the Auto- mix EDID| To cycle to the One output EDID

Communication Protocol

• The VM-24H is compatible with Kramer’s Protocol 2000. 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: Compatibility with Kramer’s Protocol 2000 does not mean that a machine uses all of the commands below. Each machine uses a sub-set of Protocol 2000, according to its needs.

Syntax

• 1st Byte:
  • Bit 7 – Defined as 0 D – DESTINATION:
  • 0 – Sends information to the switchers (from the PC)
  • 1 – Sends information to the PC (from the switcher)
  • N5…N0 – INSTRUCTION

The 6-bit INSTRUCTION defines the function performed by the switcher(s). If a function is performed using the machine’s keyboard, these bits are set with the INSTRUCTION NO. performed. The instruction codes are defined according to the table below (INSTRUCTION NO. is the value set in N5…N0).

• 2nd Byte:
  • Bit 7 – Defined as 1 I6…I0 – INPUT

When switching (i.e. instruction codes 1 and 2), the 7-bit INPUT is set as the input number to be switched. If switching is done using the machine’s front panel, these bits are set with the INPUT NUMBER switched. For other operations, these bits are defined according to the table.

• 3rd Byte:
  • Bit 7 – Defined as 1 O6…O0 – OUTPUT

When switching (i.e. instruction codes 1 and 2), the 7-bit OUTPUT is set as the output number to be switched. If switching is done using the machine’s front panel, these bits are set with the OUTPUT NUMBER 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

This byte is used to address machines in a system by their machine numbers. When several machines are controlled from a single serial port, they are usually configured together and each machine has an individual machine number. If the OVR bit is set, then all machine numbers accept (implement) the command and the addressed machine replies. When a single machine is controlled over the serial port, always set M4…M0 to 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1.

Instruction Codes

All the values in the table are decimal, unless otherwise stated

Instruction Codes for Protocol 2000

Instruction| Definition for Specific Instruction| Notes
#| Description| Input| Output|
1| SWITCH VIDEO| Set equal to video input that is switched
(0 = disconnect)| Set equal to video output that is switched
(0 = to all the outputs)| 2, 15
30| LOCK FRONT PANEL| Unlock panel
Lock panel| 0| 2
31| REQUEST WHETHER PANEL IS LOCKED| 0| 0| 16
61| IDENTIFY MACHINE| 1 – Video machine name 2 – Audio machine name 3 – Video software version 4 – Audio software version
5 – RS-422 controller name 6 – RS-422 controller version 7 – Remote control name
8 – Remote software version 9 – Protocol 2000 revision 10 – Control data machine name
11 – Control data software version| For names:
0 – Request first 4 digits 1 – Request first suffix
2 – Request second suffix 3 – Request third suffix 10 – Request first prefix
11 – Request second prefix 12 – Request third prefix

For versions:
0 – main board or the number of external board

| 13
62| DEFINE MACHINE| 1 – Number of inputs 2 – Number of outputs 3 – Number of setups| 1 – For video 2 – For audio 3 – For SDI
4 – For remote panel
5 – For RS-422 controller 6 – For control data| 14
63| EXTENDED DATA| 7 MSBs for INPUT data| 7 MSBs for OUTPUT data| 20

NOTES on the above table:

NOTE 2 – These are bi-directional definitions. If the switcher receives the code, it performs the instruction. If the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the PC sends HEX code:

• 01 85 88 83

then the switcher (machine 3) switches input 5 to output 8. If the user switches input 1 to output 7 using the front panel buttons, the switcher sends HEX code:

• 41 81 87 83

to the PC. When the PC sends one of the commands in this group to the switcher, if the instruction is valid, the switcher replies by sending the same four bytes to the PC that it received (except for the first byte, where the DESTINATION bit is set high).

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 is HEX code:

• 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 code:

• 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 code:

• 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 being addressed, not to the system. For example, if six 16×16 matrices are configured to make a 48×32 system (48 inputs, 32 outputs), the reply to the HEX code:

• 3E 82 81 82 (i.e. request the number of outputs)

would be HEX code:

• 7E 82 90 82 (i.e. 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 the same as in NOTE 4 above, except that OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 20 – When data (i.e. the INPUT and/or OUTPUT bytes) of more than 7 bits is required, instruction 63 is sent before sending the instruction needing the additional bits. The data in this instruction then becomes the most significant bits of that next instruction.

For example, to set the audio gain (instruction 22) of output 3 to 681dec (2A9hex), send HEX code:

• 3F 80 85 81

followed by HEX code:

• 16 83 A9 81.

To set the audio gain of output 6 to 10013dec (271Dhex), send HEX code:

• 3F 80 CE 81

followed by HEX code:

• 16 86 9D 81.
