4. RS-232 3-pin Terminal Block: Connect to a PC, laptop, or other serial control device with a 3-pin adapter cable for the extension of RS-232 signals to a compatible receiver.

5. LAN (POE) Port: Connect via a Gigabit Ethernet switch to compatible receiver(s) to transmit data, and to a PC/laptop to control the unit via WebGUI. Note: This unit can be powered directly by the connected Gigabit Ethernet switch if it provides PoE (802.3af).

6. DC 5V Port: Plug the 5V DC power adapter into the unit and connect it to an AC wall outlet for power. This is optional if the unit is powered by PoE.

The RS-232 3-pin Terminal Block on the CYP IP-A750TX has the following pinout:

• Pin 1: GND

• Pin 2: RxD

• Pin 3: TxD

To discover and configure the IP address of your CYP IP-A750TX, follow these steps:

1. Obtain the “Device Discovery” software from your authorized dealer.

2. Connect the CYP IP-A750TX and your PC/Laptop to the same active network.

3. Execute the “Device Discovery” software and click on “Find Devices on Internet”. A list of connected devices and their current IP addresses will be displayed. The unit defaults to Auto IP mode.

4. By clicking on one of the listed devices, you will be presented with its network details.

5. In the details window, you can change the IP Mode. You can alter the static IP network settings, or switch the unit into DHCP mode to automatically obtain network settings from a DHCP server. To switch to DHCP mode, select DHCP from the IP mode drop-down, then click “Save” followed by “Reboot”.

6. Once satisfied with the network settings, you can use the “WebGUI” hotkey in the discovery tool to launch the WebGUI directly in your browser.

Each CYP IP-A750TX is controlled by its own WebGUI interface. To access it, open a standard web browser on a PC connected to the same network and type in the IP address of the unit. If you do not know the IP address, you can find it using the Device Discovery software.

The WebGUI is organized into multiple tabs for each functional area of the unit. To view the contents of a tab, click the appropriate button at the top of the window. The main tabs are System, Network, and Functions.

The System tab contains four main sections:

1. Version Information: This window displays detailed information about the current firmware version.

2. Update Firmware: This provides a way to update the transmitter’s firmware. Click “Choose File” to select the firmware update file (*.bin format) from your local PC. After selecting a file, click the “Upload” button to begin the update process.

3. Utilities: This window allows you to reset the unit to factory defaults by clicking “Factory Default” or reboot the unit without changing settings by pressing the “Reboot” button. You can also send individual Telnet commands using the “Console API Command” text field and view the response in the “Output” field.

4. Statistics: This window shows all available information about the operational status of the unit, including current Host ID Name, Ethernet information, MAC address, unicast/multicast mode, link status, and mode.

The Network tab in the WebGUI provides controls for the transmitter’s broadcast channel, IP configuration, and network broadcast mode. Changes to these settings require a reboot.

1. Channel Setup: Use the dropdown menu to select the broadcast channel for the transmitter (0 to 255). All receivers on the local network set to the same channel will receive audio from this transmitter. Every transmitter on the same local network must have a different broadcast channel to avoid conflicts.

2. IP Setup:

• IP Mode & Settings: Switch between “Auto IP” (assigns an APIPA address), “DHCP” (obtains an address from a DHCP server), or “Static IP” (manually set IP address, netmask, and gateway). Click “Apply” to save changes.

• Find Your Device: Selecting “Show Me” will cause the PWR and LINK LEDs on the front of the unit to flash, making it easy to identify. Selecting “Hide Me” returns the LEDs to normal behavior.

3. Casting Mode: Select the broadcasting mode for the transmitter. Click “Apply” to save. Receivers must be set to the same mode as the linked transmitter.

• Multicast: Sends a single audio stream that can be played by multiple receivers simultaneously without increasing bandwidth usage. This mode is ideal for matrixing and requires a network switch with IGMP snooping enabled.

• Unicast: Uses a discrete audio stream for every connected receiver. This is ideal for simple, point-to-point setups and does not require IGMP snooping, but uses more bandwidth when multiple receivers are connected.

The Functions tab in the WebGUI provides control over audio sources, mute, gain, panel locks, and serial configuration. Changes may require a reboot.

1. Audio over IP:

• Audio Select: Select between the Optical In, Line In, or MIC In inputs on the transmitter.

• Audio Mute: Enable or disable muting of the audio output.

• Mic Input Gain: Increase or decrease the audio gain of the microphone input by dragging the slider. This is only controllable when Mic In is the selected source.

• Front Panel Lock for Device Button and Knob: Enable or disable locks for the front panel button and knob. When locked, settings can only be changed via the WebGUI or Telnet.

2. Serial over IP:

• Set the desired baud rate, data bits, parity, and stop bit for the RS-232 signal extension. The transmitter and receiver must have the same serial settings.

To control the CYP IP-A750TX via Telnet, ensure the unit and your PC are on the same active network. Use a Telnet/Console client and connect to the unit’s current IP address on port 23 (the default port). Once connected, you can enter commands directly.

Note 1: If the IP address of the unit is changed, the address required for Telnet access will also change.

Note 2: The unit defaults to Auto IP mode. The current IP address can be verified using the Device Discovery software.

The following Telnet commands can be used to control the CYP IP-A750TX. Commands are not case-sensitive and must be followed by a carriage return to be executed.
