VP-558 - Overview

The VP-558 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-558 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.

7.2.1 Setting the IR Transmission Route

IR can be routed from any of the HDBT ports to one or more of the other HDBT
ports.

For example, the HDBT 1 output connector (not the HDMI) can be used as an IR
output as well, defining the IR input via the drop down menu.

Figure 29 shows the IR signal route when setting HDBT IN 1 (IR OUT) to

HDBT IN 2. In this example, an External IR Sensor is connected to the IR
connector of the TP-580T (connected to HDBT IN 2) and an IR Emitter is
connected between the TP-580T (connected to HDBT IN 1) and a DVD player. The
DVD remote control sends a command while pointing towards the External IR
Sensor. The IR signal passes through the TP cables, the VP-558 and the IR Emitter
to the DVD player, which responds to the command sent. At the same time you can
also set HDBT IN 3 to HDBT IN 1, thus sending IR commands from HDBT IN 1 also
to HDBT IN 3 (see blue line in Figure 29). This will work only if the devices are set
appropriately.

Figure 29: HDBT IR transmission Example

7.2.2 Switching an Input to an Output

You can switch the input audio and video signals together to a selected output

9 The VP-558 RS-232 Communication

Protocol

The VP-558 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

62

VP-558 - The VP-558 RS-232 Communication Protocol

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 alphanumeric 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.

VP-558 - The VP-558 RS-232 Communication Protocol

63

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

Notes

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.

~ nn@SHOW-OSD␠ id,switch␍␊

Parameters

id – channel number 1=output 1, 2=output 2, 3=output 3, 4=output 4
switch - On/Off – 0=off, 1=on, 2=info

Response Triggers

Response is sent to the com port from which the Set (before execution) / Get command was received
After execution, response is sent to all com ports if SHOW-OSD was set any other external control device
(button press, device menu and similar) or genlock status was changed

9.3.6 Packet Protocol Structure

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

9.3.6.1 Using the Packet Protocol

To use the packet protocol:

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

2. Receive Ready or ERR###

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

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

9.3.6.2 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
