FC-404NET - Connecting the FC-404NET

Always switch off the power to each device before connecting it to your FC-404NET. After connecting your FC-404NET, connect its power and then switch on the power to each device.

You do not have to connect all the inputs and outputs, connect only those that are required.

4 Connecting the FC-404NET

To connect the FC-404NET, as illustrated in the example in Figure 2, do the following:

1. Connect up to four balanced audio sources, (for example, multimedia player, microphone) to the 3-pin Input terminal blocks 1-4.

2. Set the MIC Phantom DIP-switches according to the input type: up (OFF) for line level inputs or down (ON) for microphone inputs.

3. Connect the Output 3-pin terminal block to up to four balanced audio acceptors, (for example, an amplifier with speaker, a recording device).

4. Connect the Dante RJ-45 connector to the any available IP network.

5. If needed, connect a PC or controller to the FC-404NET via the RS-232 connection (PC only).

6. Connect the power adapter to the FC-404NET and plug the power adapter into the mains power supply.

Figure 2: Connecting the FC-404NET 4X4 Dante Interface

4.1 Connecting the Inputs

Each input channel has a 3-pin terminal block connector that can accept either a balanced or an unbalanced connection; however, an unbalanced connection requires some modifications. The next two sections explain how to connect the

FC-404NET to its input source.

4.1.1 Connecting Balanced Inputs

When using a balanced input source and connector, you must ensure that the hot, cold, and ground pins of the connector are matched up to the +, –, and ground pins of the FC-404NET terminal block connector respectively. The following diagrams illustrate how to connect standard XLR and 6.5mm phone jack.

FC-404NET - Connecting the FC-404NET

Figure 3: Connecting a Balanced XLR Input

Figure 4: Connecting a Balanced 6.5mm Phone Jack

4.1.2 Connecting Unbalanced Inputs

When using an unbalanced input source, a jumper must be added between the negative (–) and ground terminals. The unbalanced source is connected to the positive (+) and ground terminals.

Note: A jumper is required for connecting an unbalanced input.

Figure 5: Connecting an Unbalanced RCA Input

Figure 6: Connecting an Unbalanced 6.5mm Phone Jack

FC-404NET – Connecting the FC-404NET

4.2 Connecting the Outputs

Your FC-404NET is provided with a 3-pin terminal block for each output channel. This connector offers a balanced output to interface with the input of another device.

Connection methods for balanced and unbalanced outputs are identical as the methods for inputs as referenced in Section 4.1.

For any microphone that needs +48 volts of power, set the DIP-switch for that channel ON (down).

5.1 Setting the DIP-Switch

The 4-way DIP-switch on the rear panel sets the gain and enables/disables the phantom power to each channel according to the DIP-switch settings shown in the following table.

5.2 Using the Web-based Dante Controller

The FC-404NET is operated using Dante Controller, a Web-based software controller application from Audinate. Use the controller to route audio and configure devices on a Dante network. It features automatic device discovery, one-click signal routing and user-editable device and channel labels as well as providing essential device status information and powerful real-time network monitoring.

Download the Dante Web-based Controller from:

https://www.audinate.com/products/software/dante-controller

Download the Dante Web-based controller User Guide from:

http://dev.audinate.com/GA/dante-controller/userguide/pdf/latest/AUD-MANDanteController-3.6.x-v1.1.pdf

Initial or factory default input gain set according to position of DIP-switch/per channel: UP / OFF - 0 dB, DOWN / ON – +20dB.

Initial or factory default output volume always set to 0 dB

FC-404NET – Operating the FC-404NET

These values can be changed in any time through RS-232 interface by Kramer 3000 protocol commands. Input gain can be set in range -12 dB to +60 dB and output volume can be set in range +9 dB to -80 dB or Mute.

Recycling the power doesn’t change the last current values of input gain and output volume.

To execute factory default setup press and hold pushbutton DEF for about 30 sec.

The working status of the LEDs are as follows:

 SYS: System ON – green, system OFF - red  SYNC: unit is Master Green is flashing –, lights on – unit is Slave, Red lights

OFF

 Clipping – all 8 LEDs must be light OFF

7 Protocol 3000 Syntax

With Kramer Protocol 3000 you can control a device from any standard terminal software (for example, the Windows® HyperTerminal Application) or from TCP/UDP clients connected to default TCP port 5000 or UDP port 50000 (port numbers can been changed by the user). RS-232/RS-485 communications protocol uses a data rate of 115200 bps, no parity, 8 data bits, and 1 stop bit.

7.1 Host Message Format

7.1.1 Simple Command

Command string with only one command without addressing:

7.1.2 Command String

Formal syntax with commands concatenation and addressing:

7.2 Device Message Format

7.2.1 Device Long Response

Echoing command:

FC-404NET - Protocol 3000 Syntax

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

7.3 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. Multiple commands are

separated by a pipe ('|') character.

Message starting character '#' - For host command/query '~' - For machine response or machine command performed by keystroke operation on the front panel or IR remote controller.

Device address (Optional when directly connected to the device) K-Net Device ID or MACHINE NUMBER followed by '@' (ex. #02@CR LF )

Query sign '?' follows some commands to define a query request.

All outputs sign '*' defines all outputs.

Message closing character CR - For host messages; carriage return (ASCII 13)

FC-404NET – Protocol 3000 Syntax

CR LF - 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.

7.4 Entering Commands

You can directly enter all commands using a terminal with ASCII communication 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 the command parser).

For commands sent from some non-Kramer controllers such as Crestron, some characters require special coding (such as, /X##). Refer to the controller manual.

7.5 Bidirectional Definition

All commands are bidirectional. That is, if the device receives the code, it performs the instruction. If the instruction is performed (due to a keystroke operation on the front panel or IR controller) these codes are sent to the PC or other RS-232 / Ethernet controller.

7.6 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 once only, 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.

7.7 Maximum String Length

64 characters (except for special commands that are defined in the command syntax description).
