CDD-562AL/564A/L Multi-Channel Demodulator
Telnet and CLI Operation
9.1
Overview
The CLI (Command Line Interface) is a user menu system that facilitates configuration, monitoring and
control of the CDD-56xAL Multi-Channel Demodulator. This interface is accessible with a user-provided
terminal emulator application such as PuTTY, or over the Ethernet interface using Telnet.
9.1.1 Interface Access
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 screens 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).
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.
Enter 'S' from any CLI/Telnet Menu screen to save the actively set parameters.
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.
9.1.1.1
For connection via a Terminal Emulator
The user PC should be physically attached to the Console port of the CDD-56xAL. The terminal emulator
should be configured to match the Console port setting. The default Console port settings are:
•
38,400 bps
•
8 data bits
•
No parity
•
1 stop bit
•
No flow control
9.1.1.2
For connection via Telnet
The user PC must have network connectivity to the 10/100 Ethernet port of the CDD-56xAL. 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.
The CLI Interface gives all users the same access: Full Access, No Login.
