HDM-9500C or T
INSTALLATION NOTES
Almost all types of the IRENIS-BLANKOM family are 19“devices with 1 RU height designed for installation in 19” racks. In addition
to the front panel screws an internal module support is required at the rack.
Depending on the Frontend used and the operating adjustments, the SAT-RF-input ports carrying DC Voltage (13V /18V, max. 400
mA).
By connecting a mains cable, the device can become functional without any auxiliary appliances. The power supply units are
designed for the wide range of 100-230V AC; a manual adjustment of the voltage is not necessary.
For some models the second power connector is feeding another independent power supply for internal redundancy. For a
maximum of redundancy both power supplies should use different circuits.
All the outputs are decoupled from one another. Thus, the circuit does not have any effect on the functioning of the device.
Connections that are not required need not to be terminated except the unused cascaded trunk ports of the SAT multiswitches.
Suggestion:
For Ethernet cabling please use at least CAT 6E Ethernet cable for GigabitEthernet, DSTP (double shielded twisted
pair) for the streaming ports.
Note:
IPv4 global scope sessions use multicast addresses in the range 224.2.128.0 - 224.2.255.255 with SAP Announcements being sent
to 224.2.127.254 Port 9875 (note that 224.2.127.255 is used by the obsolete SAPv0 and MUST NOT be used).
IPv4 administrative scope sessions using administratively scoped IP multicast. The multicast address to be used for
announcements is the highest multicast address in the relevant administrative scope zone.
For example, if the scope range is 239.16.32.0 - 239.16.33.255, then 239.16.33.255 is used for SAP Announcements.
