Installing the VP-8x4 in a Rack
5 Installing the VP-8x4 in a Rack
This section describes how to install the VP-8x4 in a rack.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing
When installing on a 19" rack, avoid hazards by taking
CAUTION!!
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

6.5.1 Setting the Delay
You can achieve clean transitions when switching between non-genlocked
sources by setting the delay time—ranging from 0 sec to 3.5 sec1—via the
DELAY DIP-switches, as Table 5 defines. The VP-8x4 unit is shipped (its
factory default state) with no delay, that is, the DELAY DIP-switches are set up
for a 0 sec delay. The delay time is the period where the output will be forced
to black when switching between inputs.

2.0 ON OFF OFF
2.5 ON OFF ON
3.0 ON ON OFF
3.5 ON ON ON
6.5.2 Setting the Machine # DIP-switches
The Machine # determines the address of a VP-8x4 unit, specifying which
VP-8x4 unit is being controlled when several VP-8x4 units are connected to a
PC or serial controller. Set the Machine # on a VP-8x4 unit via MACH# DIPs
4, 5, 6 and 7, according to Table 6.
When using a standalone VP-8x4 unit, set the Machine # to 1. When
connecting more than one VP-8x4 unit, set the first machine (the Master) that
is closest to the PC, as Machine # 1 (DIP-switches are set to OFF).

7.4 Locking the Front Panel
To prevent changing the settings accidentally or tampering with the unit via
the front panel buttons, lock2 your VP-8x4. Unlocking releases the protection
mechanism.
To lock the VP-8x4:
Press the LOCK button for more than two seconds, until the LOCK button
is illuminated
The front panel is locked. Pressing a button will have no effect other than
causing the LOCK button to blink3
To unlock the VP-8x4:
Press the illuminated LOCK button for more than two seconds, until the
LOCK button is no longer illuminated
The front panel unlocks
1 Storing a new configuration over a previous configuration (without deleting it first) replaces the previous configuration
2 Nevertheless, even though the front panel is locked you can still operate via RS-232 or RS-485, as well as via the Kramer
RC-IR2 Infrared Remote Control Transmitter
3 Warning that you need to unlock to regain control via the front panel

Kramer Protocol 2000
11 Kramer Protocol 20001
The VP-8x4 is compatible with Kramer’s Protocol 20002, version 0.50. 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.

Kramer Protocol 2000
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.
Table 11: Instruction Codes for Protocol 2000
Note: All values in the table are decimal, unless otherwise stated.
0 RESET VIDEO 0 0 1
1 SWITCH VIDEO Set equal to video input
3 STORE VIDEO STATUS Set as SETUP # 0 - to store
4 RECALL VIDEO STATUS Set as SETUP # 0 2, 3, 15
5 REQUEST STATUS OF A
15 REQUEST WHETHER SETUP
16 ERROR / BUSY For invalid / valid input (i.e.
30 LOCK FRONT PANEL 0 - Panel unlocked
31 REQUEST WHETHER PANEL
57 SET AUTO-SAVE I3 - no save
61 IDENTIFY MACHINE 1 - video machine name
62 DEFINE MACHINE 1 - number of inputs
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).

Kramer Protocol 2000
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 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 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. 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 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 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) 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 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.
