CDD-562L/564 Demodulator with IP Module
Revision 2
CDD-56X CLI and Telnet Operation
MN/CDD564L.IOM
8–2
8.1.1 Interface Access
1. The demodulator does not allow concurrent access to the menu via Telnet
and the Console port. If the user connects via Telnet, the demodulator
automatically disables the Console port for the duration of the Telnet
session.
All Telnet-based menu pages allow a Telnet Logout to end a Telnet session.
Additionally, the demodulator automatically ends a Telnet session after a
preconfigured period of inactivity (definable from 1 to 60 minutes).
2. Any changes made to the demodulator IP parameters will be lost if the
demodulator is reset or loses power, unless the changes are first saved to
permanent storage. This applies to all of the IP parameters. Type ‘S’ from
any CLI/Telnet Menu page to save the actively set parameters.
3. All demodulator parameters configured via the CLI or Ethernet interface will
be automatically stored in the demodulator unit non-volatile RAM and will be
retained if there is a power loss.
For connection via a Terminal Emulator: The user PC should be physically attached to the
Console port of the CDD-56X. The terminal emulator should be configured to match the Console
port setting. The default Console port setting is 38,400 bps, 8 data bits, no parity, 1 stop bit and
no flow control.
For connection via Telnet: The user PC must have network connectivity to the 10/100 Ethernet
port of the CDD-56X. This connectivity can be over a local LAN, a remote LAN, or by satellite
link from another IP modem. The Ethernet Speed Mode is a configurable parameter of the
demodulator and, accordingly, its exact setting can vary between specific installations.
