PC configuring the unit with first. Otherwise, you will be locked out. The Stealth IP address
feature only supports IPv4 addresses at this time.
IP2 / GigE Management
By default, the IP1 (eth0) ports of Adtec products are reserved for management and the IP2
(eth1) ports are reserved for Transport Stream I/O. The ports can be used for either
management and/or transport with the 'Multicast Connector' configurations on TSoIP Rx and Tx
pages. To prevent unwanted users from managing the device through the IP2 port, an IP2
Management configuration has been made available on the System tab. This defaults to ON
(allow management from both IP1 and IP2 ports), but may be turned to OFF (only allow
management from IP1 interface) to further secure the device. Turning this feature OFF disables
Web UI, FTP and Telnet connectivity on the IP2 port.

DVB-S / DVB-S2 AUTO Modes
The RD-71 with L-Band demodulator (LB) option supports automatic detection of modulation
type and symbol rate on two RF inputs. In fully automatic mode, the minimum configuration
requirement is L-Band frequency. The demodulator is running in fully automatic mode when
the type is set to 'AUTO' and the symbol rate is set to '0' or 'AUTO'.
Notes about demodulator:
Please note that some carriers may not fully acquire if they fall outside of the
