Installing on a Rack

5 Installing on a Rack

This section describes what to do before installing on a rack (see section 5.1)
and how to install on a rack (see section 5.2).

5.1 Before Installing on a Rack

Before installing the machine in a 19" rack, be sure that the environment is
within the recommended range:

Table 4: Recommended Ambient Temperature and Humidity Range

Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65 % RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
Storage humidity range 5 to 95% RHL, non-condensing

5.1.1 CAUTION!!

When installing the VP-214DS in 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
supply connections other than direct connections to the branch circuit
(for example, the use of power strips), and that you use only the power
cord that is supplied with the machine.

5.2 Instructions for Rack-Mounting

To install the VP-214DS in a 19" rack, place the rack ears of the machine
against the rack rails of the rack, and insert the proper rack screws through
each of the four holes in the rack ears1.

1 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"), refer to the Rack Adapters user manual (download it at:
http://www.kramerelectronics.com) for installation instructions

Connecting a VP-214DS 4 Channel Automatic XGA Switcher

6.6 Connecting Several VP-214DS Machines

For certain applications, you may need more than just 4 channels for
switching. Cascading VP-214DS units enables you to expand the number of
2x1 switchers to be used.

You can cascade up to 8 individual VP-214DS units. For example, 3
VP-214DS units, connected via RS-232 and RS-485, will operate separately,
forming 12 separate 2x1 XGA switchers.

To cascade up to 8 individual VP-214DS units (see Figure 9), do the following:

1. Connect the XGA sources and acceptors as section 6.1 describes.

2. Turn ON the power.

3. Connect the RS-232 port on the first VP-214DS unit to the PC using the
Null-modem adapter provided with the machine (recommended), as
section 6.2 describes1.

4. Connect the RS-485 terminal block port on the first VP-214DS unit to
the RS-485 port on the second VP-214DS unit and so on, connecting all
the RS-485 ports.

5. Set the Machine dipswitches as follows:
 Set the first VP-214DS unit MACH. NO. dipswitches to Machine # 1

and the following units to Machine # 2, Machine # 3, and so on – up
to the last connected VP-214DS unit (according to Table 8)

 Set the RS-485 TERM dipswitch ON on the first (Master) and last

VP-214DS unit (terminating the RS-485 line) and set it OFF on the
remaining units

7.2 Connecting the REMOTE Connector

You may reverse the presently routed connection by using the remote control
contact closure1. To do so, connect the appropriate channel2 pin on the
REMOTE terminal block connector to the G (Ground) pin3, as Figure 10
illustrates. You can also connect several channels to G.

The input which was
not routed in channel C
is now routed to the
output

The non-routed inputs
in channels A, B and D
are now selected to
their outputs

Figure 10: Remote Terminal Block Connector

1 For example, if channel A inputs are set according to the second example in Table 10, input 1 will be routed to the output
even if it does not have an active signal
2 Channel A, B, C and/or D
3 Note that the connection should be permanent, since the VP-214DS will revert to an automatic switcher when the
connection is removed

Kramer Protocol 2000

11 Kramer Protocol 2000

The VP-214DS is compatible with Kramer’s Protocol 2000 (version 0.46)

(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.

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.

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.

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 - 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

Kramer Protocol 2000

NOTE 5 – For the OUTPUT byte set as 6, the VIS source is the input selected using the OUTPUT byte. Similarly, for the
OUTPUT byte set as 7, the VIS source is the output selected using the OUTPUT byte. Note also, that on some machines the
sync source is not software selectable, but is selected using switches, jumpers, etc!

NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with
OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction
code).

If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this function,
even for the case that the function is not defined. For example, for a video switcher which always switches during the VIS of
input #1, (and its VIS setting cannot be programmed otherwise), the reply to the HEX code
0A FE 80 81 (ie. request VIS setting, with INPUT set as 126
would be HEX codes
4A FE 81 81 (ie. VIS setting = 1, which is defined as VIS from input #1).

NOTE 7 – Setting OUTPUT to 0 will return the VIS source setting as defined in instruction #7. Setting to 1 will return the
input # or output # of the sync source (for the case where the VIS source is set as 6 or as 7 in instruction #7). Setting to 2
returns the vertical sync frequency (0 for no input sync, 50 for PAL, 60 for NTSC, 127 for error).

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 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 10 – This code is reserved for internal use.

NOTE 11 – For machines where the video and / or audio gain is programmable.

NOTE 12 - Under normal conditions, the machine's present status is saved each time a change is made. The "power-down"

save (auto-save) may be disabled using this code. Note that whenever the machine is turned on, the auto-save function is set.

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 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. 128

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. 128

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. 128

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) will cause all units (including audio, data, etc.) to switch. Similarly, if a machine is in “FOLLOW”
mode, it will perform 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 17 – For clean switching of RGBHV video, the “ seamless switching” option may be used. The blanking period for the
transition of the RGB sources may be set in this case, in steps of 25 milliseconds.
For example, to set for 350ms blanking time (14 steps), send HEX codes
07 8E A0 81

Kramer Protocol 2000

NOTE 18 – Delayed execution allows switching after a delay dictated by RS-232. To do this, the user sends instruction 7
with the “ Set for delayed switch” option (64
The switch is not executed (unless timed-out) until the “ Execute delayed switch” code is sent, or the “ Set for delayed switch”
code is sent again. (The mode is automatically cancelled after implementation of the switch if the “ execute” command is
used).
For example, to connect input 4 to output 3 after a delay, send HEX codes
07 80 C0 81 (set for delayed switch)
01 84 83 81 (switch code)
then, after the required delay, send HEX codes
07 80 C1 81 (execute delayed switch)
to implement the switch.

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.

NOTE 20 – When data (ie. the INPUT and/or OUTPUT bytes) of more than 7 bits is required, this instruction is sent before
sending the instruction needing the additional bits. The data in this intruction then becomes the Most Significant Bits of that
next instruction. For example, to set the audio gain (instruction 22) of output 3 to 681
codes
3F 80 85 81
and then send HEX codes
16 83 A9 81.
To set the audio gain of output 6 to 10013
3F 80 CE 81
followed by HEX codes
16 86 9D 81.

NOTE 21 – To store data in the non-volatile memory of the unit, eg. the EEPROM for saving SETUPS. The EEPROM
address is sent using the INPUT byte, and the data to be stored is sent using the OUTPUT byte. To use this instruction, it is
necessary to understand the memory map, and memory structure of the particular machine.

NOTE 22 – Instruction 59 and instruction 60 load data for sending to the crosspoint switcher (or for storing in a SETUP), ie.
the data is “ lined-up” to be executed later. Instruction 58 executes the loaded data.

NOTE 23 – If the INPUT byte is set as 127
byte.

NOTE 24 – 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.

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.
