QMultiFlex-400™ Installation and Operating Handbook
The modem supports the following remote-control interfaces:
•
A built-in remote web user interface that provides HTTP or HTTPS web pages from
the modem (using a web server) to a web browser. This is accessed by entering the
IP address of the modem into a web browser address bar (the web server being on
ports 80 or 443).
•
A serial interface (selectable between RS232 and RS485) that can be used to send
and receive Paradise Universal Protocol (PUP) messages. This interface can be driven
either through a generic user-entry application such as HyperTerminal (in the case of
RS232) or through an application that uses a driver developed specifically to
implement the PUP protocol. In the case of RS485, a message wrapper (defined in the
document 'Remote M&C Specification for Q-Flex™ Satellite Modem', which also
covers the QMultiFlex-400™) is used to encapsulate PUP commands and responses,
which are incorporated into the message payload.
•
An Ethernet interface that can be used to send and receive PUP messages or Simple
Network Management Protocol (SNMP) messages. This interface can be used in
several ways.
Firstly, a generic user-entry application such as Telnet can be used to automatically
send or manually enter PUP commands.
Secondly, PUP messages can be encapsulated directly into TCP packets using the
message format defined in the document 'Remote M&C Specification for Q-Flex™
Satellite Modem'. These must be sent to a specific TCP port that the modem listens
on for PUP commands. Typically, this will result in much faster communications than
when using Telnet. This method is referred to as 'direct encapsulation' elsewhere in
this document to differentiate it from the Telnet type of communications.
Thirdly, SNMP V1 or V2c can be used to communicate between an SNMP network
manager and the SNMP agent on the modem.
The remote-control protocol for the modem is specified in the document 'Remote
M&C Specification for Q-Flex™ Satellite Modem', which also covers the QMultiFlex-
400™.
M&C message example
The following example shows how to:
1)
get the transmit power from a modem. (The response has a value of -25. Note that
numeric text denotes the message contents as hexadecimal characters.)
