3Product overview
3.1 About the IP-4c
The IP-4c is a point-to-point or point-to-multipoint audio codec that uses IP-based audio network
technologies for real-time streaming. The IP-4c offers you a variety of features and opportunities to ease
your daily work.
Flexible in application: The codec is designed for studio-to-studio links, studio-to-transmitter links and
cross-media tasks. An implemented latency control even makes synchronization with microsecond accuracy
possible. This is useful for simultaneous signal output of all decoders of a network or for audio description.
Optionally enhance the IP-4c with a SAT tuner or an FM tuner that offers further functions for fallback or
backup and rebroadcasting. The Easy2connect feature provides operators as well as reporters with an easy-
to-use connection establishment (SIP phonebook) while being in the field.
High compatibility: The IP-4c supports a wide range of protocols for streaming, control, and monitoring
such as EBU TECH 3326, AES67, Ravenna, Livewire+, Dante, SMPTE ST 2110, PTPv2, RTSP, SAP, SIP,
Discovery, Bonjour, SNMP, HTTP, HTTPS, FTP, FTPS or Ember+ and more. Furthermore, the exchange of
additional information like GPIO and ancillary data between the audio networks is possible.
Pay as you grow: All software and hardware components are individually combinable. The scalability from
up to four audio channels using software licenses gives you flexibility in planning your network and
reducing your costs.
Multi-format audio coding: Another advantage is the variety of possible algorithms like MPEG1 Layer 2,
MPEG2 Layer 3, most AAC profiles including the new xHE-AAC and AAC-ELDv2, OPUS, Ogg Vorbis, PCM,
Enhanced aptX, Dolby Digital plus (on request) and more.
Transmission robustness: Dual Streaming and Pro-MPEG FEC ensure rock-solid IP transmission, or you go
beyond with Stream4Sure. RIST and SRT allow for efficient packet recovery with low bandwidth. Two hot-
pluggable power supplies that guarantee fail-safe operation perfect the whole concept.
Smart management: Configuration set-up via an easy-to-use web interface for general settings as well as
for backup or fall back. For remote control, the codec offers various possibilities HTTP, HTTPS, SFTP,
Ember+, NMOS, NMS, and SNMP. Perfect synchronization can be achieved by PTPv2 and latency control.

5.1 Configuring the interface services
For each ethernet interface, you can select the services by which the interface can receive and send data.
To select the supported services.
1. Navigate to the page Services.
2. For each individual interface, define which data can be received and sent.
3. Click Save.
✓The interfaces now only support the selected services.
5.2 TCP/IP: Configuring the ethernet interfaces
The IP-4c has several Ethernet interfaces: 1 for configuration and the others for data exchange. Configure
the interfaces for data transmission.
NOTICE
False connection of the Ethernet interfaces will lead to incorrect operation!
➢Use the [Data] interfaces only for data transfer.
➢Use the [Ctrl] interface only for the access to the device via the web interface and
for SNMP.

To configure the ethernet interfaces:
1. Navigate to the page TCP/IP.
2. Configure the parameters for the DNS Server, Ctrl and Data interfaces.
The necessary address settings depend on the individual network and should be
assigned by the responsible network administrator, if applicable.
3. Click Save.
✓The ethernet interfaces are now configured.
Parameters
Primary
Enter the IP address of the primary domain name server (DNS).
Secondary
Enter the IP address of the secondary domain name server (DNS).
Routing
Enable the Routing, which enables the DNS server to send and answer the requests over
different [Data] interfaces.
VLAN
Enable VLAN and enter the VLAN ID (1-4095).
Priority
Assign a priority (1-7) to this stream to add a priority code point (PCP) according to the
IEEE 802.1Q specification. Select 0 to disable the priority and use best-effort delivery.
DHCP
Enable dynamic host configuration protocol (DHCP) which enables the device to get an IP
address automatically.
IP Address
If DHCP is disabled, then assign an IP address to the interface.
Subnetmask
Enter the subnetmask for the IP address.
Gateway
Enter the address of the local system that is used for the internet access (e.g. the router).
Speed
The speed is set to auto.
Mode
The mode is set to full duplex.
5.3 Monitoring the device via syslog
In addition to saving information about events in the log, you can also send them to a syslog server. Syslog
eases monitoring the IP-4c.
To send event information to a syslog server:
1. Navigate to the page Syslog.
2. Enable at least one of the servers.
3. Configure the parameters.
4. Click Save.
✓The IP-4c now sends event information to the syslog server(s).
Parameters
IP address
Enter the IP address of the syslog server.
Port
Enter the port number.
Protocol
Select the protocol to be used.
Lowest level
Select the lowest level of a message that will be sent to the syslog server. For more
information, see 11.8 Priority of alarm messages.
Interface
Select the [Data] interface to be used.

VLAN
If the selected [Data] interface is an interface with VLAN, then select the VLAN to be used.
5.4 SNMP: Configuring access data for external requests
You can configure access data (read community/write community) that is necessary for external SNMP
requests to the IP-4c.
For the SNMP manager tool to operate correctly, it requires the specific MIB files. These
MIB files must be compiled by your SNMP manager tool. You can save the MIB files in
the block MIB File.
1. Navigate to the page External APIs.
2. Click on the tab SNMP.
3. Select the protocol version in the block SNMP Protocol.
4. Configure the parameters in the block Read/Write Community or SNMP3 / Security. The parameters
differ depending on the selected protocol version.
5. Click Save.
✓You have configured the access data for external SNMP requests.
Parameters
Read Community
Enter SNMP access data for the external read-only SNMP access to the device.
Write Community
Enter SNMP access data for the external write SNMP access to the device.
Read/Write user
Enter user name and password for the external write SNMP access to the device.
Read/Write user
Enter user name and password for the external read-only SNMP access to the device.
Security protocols
Select an authentication protocol and a privacy protocol.
5.5 SNMP: Configuring trap managers
As part of the monitoring function, the device is capable to send SNMP traps to the defined IP addresses of
the SNMP managers. It is also possible to readout device settings via SNMP Get.
For the SNMP manager tool to operate correctly, it requires the specific MIB files. These
MIB files must be compiled by your SNMP manager tool. You can save the MIB files in
the block MIB File.
1. Navigate to the page External APIs.
2. Click on the tab SNMP.
3. Select the protocol version in the block SNMP Protocol.
4. Select the location of the table indices in the block Trap Configuration: OID or OID plus additional
index.
5. Configure the parameters in the block Trap Manager.
6. Click Save.
✓You have configured the trap managers. If you changed the location of table indices, the IP-4c must
reboot. Each enabled trap is sent once at startup for initialization.
Parameters
Version
Select the format version of the SNMP traps.
