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

• 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

9.1 Data Handling Performance

The FC-21ETH, FC-22ETH and FC-24ETH are designed to support mainly AV-relevant 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.

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).

10 Default Communication Parameters

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

Start	Address(optional)	Body	Delimiter
#	Destination_id@	Message	CR

11.1.1.1 Simple Command

Command string with only one command without addressing:

Start	Body	Delimiter
#	Command SP Parameter_1,Parameter_2,...	CR

11.1.1.2 Command String

Formal syntax with commands concatenation and addressing:

Start	Address	Body	Delimiter
#	Destination_id@	Command_1Parameter1_1,Parameter1_2,...|Command_2Parameter2_1,Parameter2_2,...|Command_3Parameter3_1,Parameter3_2,...|...	CR

11.1.2 Device Message Format

Start	Address(optional)	Body	delimiter
~	Sender_id@	Message	CR LF

11.1.2.1 Device Long Response

Echoing command:

Start	Address (optional)	Body	Delimiter
~	Sender_id@	Command SP [Param1,Param2 ...] result	CR LF

CR= Carriage return (ASCII 13 = 0x0D)

LF = Line feed (ASCII 10 = 0x0A

= 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.

Spaces between parameters or command terms are ignored.

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.

11.1.7 Maximum String Length

64 characters
