VP-553xl - Overview

3 Overview

The VP-553xl is a high-performance 6x2 presentation switcher/scaler for HDMI™,
HDBaseT and analog signals, and a 4x1 USB switcher. The unit has dual,
independent, scaled outputs, the first on both HDMI and HDBaseT connectors,
and the second on an HDMI connector. Both can take from the six digital inputs:
three HDBaseT and three HDMI signals; while the first also includes analog inputs
– for two computer graphics signals, two composite video and two analog TP
inputs. Analog, digital and embedded audio are supported, and the unit also
includes a microphone input and rich DSP features.

The VP-553xl features:

• Pix-Perfect™ scaling technology - Kramer’s precision pixel mapping and

high quality scaling technology. High-quality 3:2 and 2:2 pull down
de-interlacing and full up- and down-scaling of video input signals

• System Range for the HDBT inputs and outputs - Up to 70m (230ft)

For optimum range and performance using HDBaseT™, use Kramer's
BC-UNIKat cable. Note that the transmission range depends on the
signal resolution, source and display used. The distance using
non−Kramer CAT 6 cable may not reach these ranges.

• System Range for the TP inputs and outputs - over 250m (more than 820ft)

For optimum range and performance using TP, use Kramer's BC-STP
cable where skewing is not an issue or the Kramer BC-XTP Unshielded
Twisted Pair (UTP) skew-free cable. Note that the transmission range
depends on the signal resolution, source and display used. The
distance using non−Kramer CAT 6 cable may not reach these ranges.

• HDTV compatibility

• HDCP compliance - the HDCP (High Definition Content Protection) license

agreement allows copy-protected data on the HDMI input to pass only to the
HDMI outputs

• Video inputs - three HDMI connectors, two VGA on 15-pin HD connectors

each with unbalanced stereo audio on 3.5mm connectors, two composite
video on RCA connectors with unbalanced stereo audio on RCA connectors,
three HDBaseT on RJ-45 connectors and two analog TP on RJ-45
connectors

VP-553xl - Overview

Control your VP-553xl:

• Directly, via the front panel push buttons

• By RS-232 serial commands transmitted by a touch screen system, PC, or

other serial controller

• Remotely, from the infrared remote control transmitter with OSD (on−screen

display)

• Via the Ethernet with built-in Web pages

The VP-553xl is housed in a 19” 2U rack mountable enclosure, with rack “ears”

included, and is fed from a 100-240 VAC universal switching power supply.

3.1 Using the USB Switcher

The VP-553xl incorporates a simple, yet effective, 4:1 USB 1.1 switcher. The
switcher can be used, for example, to connect one out of several PCs to a smart
board or other USB client.

The USB switcher can be routed as a separate layer, or can be tied to the video
switching layer of the unit. This creates a powerful “USB follows video” system – the
PC routed to the display also connects to the smart board. In many meeting room
setups these USB switching schemes are highly effective.

3.2 Using Twisted Pair Cable for HDBT

Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; BC−UNIKat (CAT 6 23 AWG cable) significantly
outperforms regular CAT 5 / CAT 6 cables.

We strongly recommend that you use shielded twisted pair cable.

i

VP-553xl – Overview

7

3.3 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)

We recommend that you use Shielded Twisted Pair (STP) cable, and stress that the
compliance to electromagnetic interference was tested using STP cable. There are
different levels of STP cable available, and we advise you to use the best quality
STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is
intended for analog signals where skewing is not an issue.

In cases where there is skewing in analog TP systems, our Unshielded Twisted Pair
(UTP) skew-free cable, Kramer BC-XTP, may be advantageous, and UTP cable
might also be preferable for long range applications. In any event when using UTP
cable, it is advisable to ensure that the cable is installed far away from electric
cables, motors and so on, which are prone to create electrical interference.

VP-553xl - The VP-553xl RS-232 Communication Protocol

9 The VP-553xl RS-232 Communication

Protocol

The VP-553xl can be operated using serial commands from a PC, remote
controller, or touch screen. The unit communicates using the default Kramer
Protocol 3000.

• Kramer Protocol 3000 syntax (see Section 9.1)

• Kramer Protocol 3000 command list (see Section 9.2)

• Kramer Protocol 3000 detailed commands (See Section 9.3)

9.1 Kramer Protocol 3000 Syntax

Protocol 3000 communicates at a data rate of 115200 baud, no parity, 8 data bits
and 1 stop bit.

9.1.1 Host Message Format

Start

Address (optional)

Body

Delimiter

#

Destination_id@

Body

Delimiter

~

Sender_id@

Command SP [Param1 ,Param2 …] result

CR LF

VP-553xl – The VP-553xl RS-232 Communication Protocol

51

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

9.1.3 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 alphameric 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 machine 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 machine 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.

52

VP-553xl - The VP-553xl RS-232 Communication Protocol

9.1.4 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.

9.1.5 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.

9.1.6 Command Chaining

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.

9.1.7 Maximum String Length

64 characters

When the unit receives the LDEDID command it replies with READY and enters the special EDID packet
wait mode. In this mode the unit can receive only packets and not regular protocol commands.
If the unit does not receive correct packets for 30 seconds or is interrupted for more than 30 seconds

before receiving all packets, it sends timeout error ~nn @LDEDID␠ ERR01␍␊ and returns to the regular
protocol mode. If the unit received data that is not a correct packet, it sends the corresponding error and

returns to the regular protocol mode.

9.3.5 Packet Protocol Structure

The packet protocol is designed to transfer large amounts of data, such as files, IR
commands, EDID data, etc.

9.3.5.1 Using the Packet Protocol

To use the packet protocol:

1. Send a command: LDRV, LOAD, IROUT, LDEDID

2. Receive Ready or ERR###

78

VP-553xl - The VP-553xl RS-232 Communication Protocol

3. If Ready:

▪ Send a packet
▪ Receive OK on the last packet
▪ Receive OK for the command

4. Packet structure:

▪ Packet ID (1, 2, 3…) (2 bytes in length)
▪ Length (data length + 2 for CRC) - (2 bytes in length)
▪ Data (data length -2 bytes)
▪ CRC - 2 bytes

CRC

5. Response:

~NNNNSPOKCR LF

Where NNNN is the received packet ID in ASCII hex digits.

9.3.5.2 Calculating the CRC

The polynomial for the 16-bit CRC is:
CRC-CCITT: 0x1021 = x16 + x12 + x5 + 1
Initial value: 0000
Final XOR Value: 0

For a code example, see:

http://sanity-free.org/133/crc_16_ccitt_in_csharp.html

CRC example:
Data = “123456789”
Result => 0x31C3
