“IP RX” menu
To configure the 8 IP inputs, start by clicking on the item “IP RX 1”, “IP RX2”, “IP RX3”, „IP RX4” etc. in
the menu at the left. The following table will then appear in the content area at the top:
Figure 25: Table 1 “IP RX1 channel settings”
“Receive IP” and “Port” (see lines 1, 3 and 5 in the table) form a socket on which the incoming data
stream is received. This also allows the Receive IP address to be a multicast address or a unicast address of its own.
The IGMP protocol is used to request an IP multicast. If version 3 of this protocol is used, then you can
select a specific source using the Source Select IP address (see lines 2, 4 and 6 in the table). If this
function is to remain unused, please enter four zeroes in the input field. (This is, for example, the case
when IGMP version 2 or IBMP version 3 from any source is being used as the protocol).
You can make a priority setting for the primary, secondary and tertiary IP address / port respectively
using a drop-down menu. There are 13 options (from “off” to “highest/hot”) available for selection.
The priorities are divided into three groups:
Hot standby (higher priorities) Levels 7 - 12: data streams are requested permanently
Cold standby (medium priorities): Levels 1 - 6
“Off”
As a rule – providing there are no network provider problems – the data stream with the highest priority
is received and used for processing. In the event of a fault – failure of the incoming signal – a
switch-over is made to the data stream with the next-highest priority.
If a priority level from the “Hot standby” group is allocated to a data stream, then this will continue to be
requested even during network provider problems. As soon as the problem has been rectified, it switches back to this data stream.

Select either the “Primary”, “Secondary” or “Tertiary” option from the second drop-down menu.
Select the “static” option from the third drop-down menu if you do not wish to use an automatic
replacement circuit for the data streams. Select the “automatic” option when the replacement
circuit should be used as described above.
Timeouts: Enter a time frame, in seconds, in the first input field after which a switch-over to the
data stream with the next-lowest priority should occur in the event of a fault.
Enter a time frame, in seconds, in the second input field after which it should switch back to the
data stream with the higher priority after the problem has been rectified. (This is only the case
when a priority level from the “Hot standby” group was allocated to the data stream - see explanation above).
Error condition: If the data rate should be the only factor in the event of a fault, activate the
radio button “data rate only”. Otherwise, select the radio button “data rate, continuity count,
service”.
Encapsulation: When the radio button “RTP / UDP / IP” has been activated, the corresponding
RTP / UDP / IP data streams are received. If you activate the radio button “on” in the line “FEC”,
then the additional receive IP ports +2 and +4 will be received (example: apart from 10000, also
10002 and 10004). Additional redundancy information for fault correction is included in this.
When the radio button “UDP / IP” has been activated, either UDP / IP data streams or RTP / UDP
/ IP data streams without an evaluation from RTP are received.
Select either “automatic” or “manual” for the data encapsulation by clicking the corresponding
radio button.
Bitrate: Select either “automatic” or “manual” by clicking the corresponding radio button. If
“manual” is selected and the radio button “Single PCR” has been selected at the same time, then
the receive data stream is regulated using a single PCR. This is not suitable for transport streams
with several PCRs.
If you activate the radio button “Multi PCR”, then the data rate is used for regulation. This is not
possible for data streams with a variable bit rate.
FEC: Activate or deactivate the FEC by clicking the radio button “on” or “off”. (See “Encapsulation”
above.)
TSID / ONID: The respective value is displayed but cannot be changed.
Alias manual / automatic: You can enter an alias name for the data stream in the input
field at the left. The automatically generated alias name is displayed at the bottom right. This is
the name of the first transmitter in the data stream. This is used if no name is entered manually.

The following parameters are displayed for the individual IP receivers:
Encap: The number of bytes in the IP payload for each frame is specified in the upper line; below
this, the number of TS packets per frame is displayed. The lower line specifies whether the transmission occurs by UDP / IP or TRP / UDP / IP. The transmission protocol is selected under the
menu item “IP RX” in the table line “Encapsulation”.
TS Rate: The net data rate is specified in the upper line; the lower line displays whether the trans-
port stream includes one, or a multiple, PCR. This setting can be made under the menu item “IP
RX” in the table “Channel settings”, line “Bit rate”.
Buffer depth: The absolute buffer depth is displayed in the upper line (number of frames);
below this, the relative buffer depth (in %) is displayed. The buffer depth is displayed in relation to
the transport stream rate in the third line.
FEC: If an RTP data stream is being used, the FEC configuration detected is displayed here.
Prerequisite for this is that FEC has been activated in the “IP RX” menu (radio button “ON”).
Valid: Total number of valid IP frames.
Missing: Total number of IP frames not received (is only measured when RTP is used).
Fixed: When Forward Error Correction (FEC) is activated, missing or defective frames can be
restored. The number of frames which were restored is displayed.
Duplicate: The number of IP frames received several times (is only displayed when RTP is
used).
Reordered: The number of IP frames arriving in the wrong order, but which were able to be
switched back due to a sufficient buffer depth (is only displayed when RTP is used).
Out of range: The number of IP frames arriving in the wrong order and which could not be
switched back due to an insufficient buffer depth.

Troubleshooting
Operating manual U 224 - Version 10-2018A
Troubleshooting
If the device is not functioning correctly, please perform the following checks:
Check whether the device is connected to the required mains voltage (230 V~, 50 Hz).
Check whether the signal cable is connected correctly, and that there are no breaks or short
circuits in the connectors.
If the problem cannot be resolved, please contact the ASTRO customer service.
Maintenance and repair
ACHTUNG: The following safety information must be observed when performing main-
tenance and repair work. Failure to observe this safety information may result in personal
injury due to electrical and thermal dangers!
The operating display only shows whether the DC current, which supplies the device components,
has been disconnected from the mains voltage. If the operating display (for the power supply unit
or the device) does not light up, this does not mean that the device has been fully disconnected
from the mains voltage. There may still be voltages in the device that are dangerous to touch. You
may therefore not open the device.
The cover for the power supply unit is designed to prevent accidental contact with voltages that
are dangerous to touch, and must not be removed.
Read carefully: EN 60728 - Part 1 Safety requirements: No service work during thunderstorms.
A defective device may only be repaired by the manufacturer to ensure that components with the
original specification are used (e.g. power cable, fuse). Improperly performed repairs may result
in considerable dangers for the user or installer. If malfunctions occur, the device must therefore
be disconnected from the mains and authorised experts must be consulted. The device may need
to be sent to the manufacturer.
Service tasks
The following tasks, which involve the removal of screw connections, can be performed by appropriately instructed service personnel: Removal and installation of power supply units.
Replacing power supply units
After removing the screws from the cover of the power supply unit chamber (ASTRO logo), the power
supply units can be pulled forwards by hand using the mounting tab. When installing power supply
units, do not touch the fan or fan grille and only use the mounting tab affixed to the power supply unit.
When the tasks are complete, the cover of the power supply unit chamber must be replaced. Continuous operation of the device is not permitted without this cover.
ACHTUNG: Do not put your hand or any objects into the power unit chamber of the device!
HINWEIS: The U 224 must only be operated with the original power unit(s)!
