6 Operating the VS-41H

This section describes:

• The PC mode and the DVD mode (see Section 6.1

• How to acquire the EDID (see Section 6.2)

• How to control the machine via RS-232 (see Section 6.3)

• How to control the machine via the Ethernet port (see Section 6.4)

6.1 The PC and DVD Modes

The VS-41H has two operation modes that can be set individually for each input: the PC mode (default) and the DVD mode:

• Use the PC mode when connecting one or more computers to the inputs

using a DVI-to-HDMI converter cable

For example, the Kramer HDMI-DVI gol d-plated cable in various lengths (3”, 6”, 10” and 15”).

• Use the DVD mode when connecting one or more DVDs to the inputs

In the PC mode, an input always has access to the EDID (default or acquired) to prevent the computer from resetting if the output is not connected.

In the DVD mode, an input only has access to the EDID when it is switched to the connected output.

The PC mode and the DVD mode can be applied to a single unit or to several inputs. For example, if you want to connect computers to INPUTS 1 and 2, and DVD machines to INPUTS 3 and 4, set INPUTS 1 and 2 to the PC mode and INPUTS 3 and 4 to the DVD mode.

)

To set the inputs to either the PC or DVD mode, do the following:

1. Turn off the VS-41H POWER.

2. Press the PANEL LOCK button while turning the POWER on again.

9 Protocol 2000

Kramer Protocol 2000 for RS-232/RS-485 communication uses four bytes of information as defined below.

2nd byte OUTPUT

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 o per a ti ons, these bits are de fi ne d acc or ding 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 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.

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

NOTES on the above tabl e: 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 – 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

2 - for audio 3 - for SDI 4 - for remote panel

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 1 3 – 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 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 by t e, an d 12 8dec+ 16dec for 3rd by te) .

If the request for identification is sent with the INPUT set as 3 or 4, 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 2n d byt e , 128 dec+ 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 exampl e, 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 1 4 – 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 (i.e. request the number of outputs) would be HEX codes 7E 82 90 82 i.e. 16 outputs

NOTE 1 5 – When the OVR bit (4th byte) is set, then the “video” commands have universal meaning. For example, instruction 1 (SWITCH VIDEO) will cause all units (inclu ding audio, data, etc.) to switch. Similarly, if a machine is in “FOLLOW” mode, it will perform any “video” instruction.

NOTE 2 4 – Further information needed in instructions 21, 22, 25 and 26, is sent using instruction 42 – which is sent prior to the instruction. For example, to request the audio gain value of right input # 9, send hex codes 2A 84 80 81 and then send HEX codes 19 89 81 81. To set MIX mode, send hex codes 2A 81 84 81 and then send HEX codes 16

NOTE 2 5 – 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.
