Overview
3 Overview
The FC-21ETH, FC-22ETH and FC-24ETH are a family of high-performance,
easy-to-use, bidirectional hardware and software interface systems for controlling
RS-232 and/or RS-485 controllable machines via an Ethernet LAN, as well as via
the Internet.
These Ethernet to serial controllers bridge the gap between Ethernet
infrastructures and serial communication devices by offering bidirectional Ethernet
to serial conversion. All setup and maintenance of the devices is done from built-in
Web pages which are accessible using any common Web browser. All devices
offer one RS-232/RS-485 dual-use serial port.
In particular, the FC-21ETH, FC-22ETH and FC-24ETH:
Offer network connectivity that lets you connect a Kramer (or other) device
via its RS-232 or RS-485 port to an Ethernet LAN
Let you control up to three RS-232 devices and one RS-485 device (model
dependent) via Ethernet from a PC
Let you control a device from multiple Ethernet points (PCs or remote
controllers), via a LAN or the Internet
Include Windows® based Virtual Port software for setting up virtual ports on
a PC
Support Internet-based, remote firmware upgrades
Can be rack mounted in a 1U rack space with the optional rack adapters
More specifically, the FC-21ETH, FC-22ETH and FC-24ETH feature:
One RS-232/RS-485 port (FC-21ETH), one RS-232 and one RS-232/RS-
485 port (FC-22ETH), three RS-232 and one RS-232/RS-485 ports
(FC-24ETH)
An Ethernet LAN connection
Static or dynamic (DHCP) IP addressing
A USB port for upgrading the firmware
Overview

A 5V DC power supply
A compact Kramer TOOLS™ enclosure (FC-21ETH, FC-22ETH) or
MegaTOOLS™ enclosure (FC-24ETH) which can be mounted side by side
in a 19-inch rack using suitable rack adapters
The FC-21ETH, FC-22ETH and FC-24ETH include the Virtual Serial Port Manager
(Kramer VSPM) for compatibility with applications based on COM-port
communication. The virtual serial port:
Makes the FC-21ETH, FC-22ETH and FC-24ETH compatible with all
Windows®-based applications which require a physical COM port. This
includes all versions of K-Router and other Kramer control applications. It
lets you operate all RS-232 and RS-485 controllable devices via an Ethernet
LAN using their existing PC software
Operates like a physical COM port, that is, a logical COM port that behaves
like a standard hardware COM port. In reality, it transparently reroutes the
data using the TCP/IP network to the FC-21ETH, FC-22ETH or FC-24ETH
interface via a virtual connection which you can emulate over the Ethernet or
Internet
Can be created in any quantity on your PC and does not occupy a physical
serial port

9 Technical Specifications
9.1 Data Handling Performance
The FC-21ETH, FC-22ETH and FC-24ETH are designed to support mainly AVrelevant RS-232 communication.
These devices have overall data bandwidth limits which should be high enough in
most AV installations to support the required communication bandwidth.
36
Technical Specifications
In extremely demanding cases, we recommend that you take into account the
bandwidth limitations.
The total sustained data bandwidth that each device can handle for all ports
simultaneously is as follows:
FC-21ETH—150kbps
FC-22ETH—140kbps
FC-24ETH—180kbps
9.2 Example Bandwidth Calculation
The FC-22ETH has two serial ports. Each serial port can support up to:
140kbps / 2 = 70kbps
If each of your protocol commands is 100 bytes, (that is, 800bits), you can safely
send and/or receive a minimum of 85 of these commands per second on each
serial port ((140kbps * 1024) / 800bits / 2 = 89.2). The same calculation applies to
all devices. A similar calculation applies when fewer ports are used at the same
time; in this case higher bandwidth per port can be achieved.
In critical applications requiring a lossless data transfer, we recommend that
communication on all the other ports is stopped when making a long file transfer
(for example, when performing a firmware upgrade via one of the serial ports).

11 Kramer Protocol 3000
The FC-21ETH can be operated using serial commands from a PC, remote
controller or touch screen using the Kramer Protocol 3000.
This section describes:
Kramer Protocol 3000 syntax (see Section 11.1)
Kramer Protocol 3000 commands (see Section 11.2)
11.1 Kramer Protocol 3000 Syntax
11.1.1 Host Message Format
11.1.1.1 Simple Command
Command string with only one command without addressing:
11.1.1.2 Command String
Formal syntax with commands concatenation and addressing:
11.1.2 Device Message Format
11.1.2.1 Device Long Response
Echoing command:
Kramer Protocol 3000
39
CR = Carriage return (ASCII 13 = 0x0D)
LF = Line feed (ASCII 10 = 0x0A)
SP = Space (ASCII 32 = 0x20)
11.1.3 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 device 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 device 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.

11.1.4 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.
11.1.5 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.
11.1.6 Chaining Commands
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.
