Chapter 6. SERIAL-BASED REMOTE PRODUCT MANAGEMENT Introduction Serial‐based Remote Product Management of the CDM‐800 Gateway Router is available using the rear panel ‘CONSOLE’ port. 1. To proceed with Serial‐based Remote Product Management, assumptions are made that: • The CDM‐800 Gateway Router is operating with the latest version firmware files. • The CDM‐800 is connected to a user‐supplied Windows‐based PC as follows: o The PC serial port is connected to the CDM‐800 rear panel ‘CONSOLE’ port using a user‐supplied serial cable. o The PC Ethernet port is connected to the CDM‐800 rear panel ‘MANAGEMENT | FE’ 10/100 BaseT Ethernet port with a user‐supplied hub, switch, or direct Ethernet cable connection. o The PC is running a terminal emulation program (for operation of the CDM‐800 Serial Command Line Interface) and a compatible Web browser (for operation of the CDM‐800 Web Server Interface). • The CDM‐800 Management IP Address has been noted using the CDM‐800 Serial Command Line Interface (CLI). 6–1...

Figure 5-1. CDM-800 Serial Interface Example CDM‐800 Serial Remote Product Management is available through the EIA‐232 operational interface, where the ‘Controller’ device (the user PC or an ASCII dumb terminal) is connected directly to the ‘Target’ device (the CDM‐800 Gateway Router, via its DB‐9M ‘CONSOLE’ port). This connection makes possible serial remote monitor and control (M&C) of the CDM‐800 through its Serial Command Line Interface (CLI). Through this EIA‐232 connection (for the control of a single device), data is transmitted in asynchronous serial form, using ASCII characters. Control and status information is transmitted in packets of variable length in accordance with the structure and protocol defined later in ...
CDM-800 Gateway Router Revision 1 Serial-based Remote Product Management MN-CDM800 When the user‐supplied terminal emulator program is configured correctly, upon power‐up of the CDM‐800, the CLI Info Screen appears, followed by the CLI command prompt CDM‐800>. From here, type “help[cr]” or “?[cr]” (without the quotes) to display the ...
CDM-800 Gateway Router Revision 1 Serial-based Remote Product Management MN-CDM800 6.2.2.2 Target Address In EIA‐232 applications, this value is set to 0000. The Target Address designates the packet destination. The Controller does not have its own address. After the Controller sends a packet with the designated Target Address, the Target responds to the Controller, using this same address, to indicate the source of the packet.
CDM-800 Gateway Router Revision 1 Serial-based Remote Product Management MN-CDM800 6.2.2.5 Instruction Code Qualifier This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules: From Controller‐to‐Target, the only permitted characters are: Character Definition This character is used as the Assignment Operator (AO). It establishes that the Instruction Code that precedes it is to (ASCII code 61) be used as a command to assign or configure operation.
CDM-800 Gateway Router Revision 1 Serial-based Remote Product Management MN-CDM800 Character Definition If the Controller sends an instruction code that the Target does not recognize, the Target responds by echoing the invalid instruction, followed by ! (ASCII code 33) Example: CMD!
CDM-800 Gateway Router Revision 1 Serial-based Remote Product Management MN-CDM800 Remote Commands and Queries The Serial Command Line interface (CLI) (the Controller), shown previously in Figure 5‐1, is used to issue remote commands and queries to the CDM‐800 (the Target). From the CLI command prompt CDM‐800> type in the command or query packet, using the format explained previously, for transmission to the CDM‐800. For example: CDM‐800><0000/LC1=3[cr] The table that follows provides a ‘quick reference‘ to the Instruction Codes available at present for M&C of the CDM‐800.

Appendix A. FAST FAST Overview The CDM‐800 Gateway Router incorporates a number of optional features. In order to permit a lower initial cost, the unit may be purchased with only the desired features enabled. If, at a later date, the user wishes to upgrade the functionality of a unit, Comtech EF Data provides Fully Accessible System Topology (FAST), which permits the purchase and installation of options through special authorization codes. These unique Fast Access Codes may be purchased from Comtech EF Data during normal business hours, and then loaded into the unit using the Web Server Interface (accessible via the CDM‐800 rear panel ‘FE’ port). ...

Appendix B. FEC (FORWARD ERROR CORRECTION) Introduction The method of FEC (Forward Error Correction) used by the CDM‐800 Gateway Router is based upon the DVB‐S2 standard for QPSK, 8PSK, 16APSK and 32APSK with concatenated Low Density Parity Code (LDPC) and Bose‐Chaudhuri‐Hocquenghem (BCH). DVB-S2: LDPC and BCH The DVB‐S2 specification has defined a new generation of performance that boosts throughput by about 30% over DVB‐S using the same amount of bandwidth. This new type of coding and modulation far exceeds the capability of concatenated Viterbi and Reed Solomon coding. LDPC and BCH is also a concatenated error correction technique. LDPC is a very powerful coding scheme with significant, Near‐Shannon Bound Performance. In some cases, as the carrier‐to‐noise ...
* Taken at the -10 dB points on the plot of power spectral density, the occupied bandwidth is 1.19 x Symbol Rate for 35%, and 1.15 x Symbol Rate for 25%. CDM-800 Error Performance Characteristics On the pages that follow, Figure B‐1 through Figure B‐4 illustrate the guaranteed error ...
