Chapter 6. SERIAL-BASED REMOTE PRODUCT MANAGEMENT Introduction Serial‐based Remote Product Management of the LBC‐4000 L‐Band Up/Down Converter System is available using the rear panel ‘J1 COM1’ port. This interface is either an EIA‐485 multi‐drop bus (for the control of many devices) or an EIA‐232 connection (for the control of a single device), and 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 in later sections. ...

LBC-4000 L-Band Up/Down Converter System Revision 4 Serial-based Remote Product Management MN/LBC4000.IOM 6.1.1 EIA-485 For applications where multiple devices are to be monitored and controlled, a full‐duplex (4‐wire plus ground) EIA‐485 is preferred. Half‐ duplex (2‐wire plus ground) EIA‐485 is possible, but is not preferred. In full‐duplex EIA‐485 communication, there are two separate, isolated, independent, differential‐mode twisted pairs, each handling serial data in different directions. It is assumed that a 'Controller' device (a PC or dumb terminal) transmits data in a broadcast mode via one of the pairs. Many 'Target' devices are connected to this pair, and all simultaneously receive data from the Controller. The Controller is the only device with a line‐ driver connected to this pair; the Target devices have only line‐receivers connected. ...
LBC-4000 L-Band Up/Down Converter System Revision 4 Serial-based Remote Product Management MN/LBC4000.IOM Remote Commands and Queries Overview 6.2.1 Basic Protocol Whether in EIA‐485 or EIA‐232 mode, all data is transmitted as asynchronous serial characters, suitable for transmission and reception by a UART. The default asynchronous character format is 8‐N‐1 (8 data bits, no parity, one stop bit). The supported baud rates are 1200, 2400, 4800, 9600, 19K2 (19200), or 38K4 (38400) bps. All data is transmitted in framed packets as asynchronous serial characters, suitable for transmission and reception to the Controller using a universal asynchronous receiver/transmitter (UART). Controller‐to‐Target data is carried via EIA‐232 electrical levels on one conductor, and Target‐to‐Controller data is carried in the other direction on the other conductor: • Controller‐to‐Target – The Controller device (e.g., the user PC) is used to transmit instructions (commands) to – or to request information from (queries) – the Target device (i.e., the LBC‐4000). • Target‐to‐Controller – The Target, in return, only transmits response information to the Controller when specifically directed by the Controller. For Serial Remote Control, all issued commands (Controller‐to‐Target) require a response (Target‐to‐Controller). This response is either to return data that has been queried by the Controller, or to confirm the Target’s receipt of a command to change the Target’s ...

Appendix B. LBC-4000 REDUNDANCY OPERATION Introduction The LBC‐4000 L‐Band Up/Down Converter System can optionally be configured for redundant system operation. This appendix provides detailed information for cabling and otherwise configuring the LBC‐4000 for 1:1 redundancy. Redundancy Operations Overview • Figure B‐1 provides a functional schematic for LBC‐4000 redundant operation. • Figure B‐2 illustrates the cabling requirements for redundant operation. Note the following: ...
LBC-4000 L-Band Up/Down Converter System Revision 4 Appendix B MN/LBC4000.IOM Redundancy Operations via the LBC-4000 Front Panel You can configure, monitor, and control redundancy operation via the LBC‐4000 front panel, using the keypad and display. Nested menus are used, which display all available options, and prompt you to carry out a required action. Figure B‐3 identifies the key features of the LBC‐4000 front panel; see Chapter 5. FRONT PANEL OPERATION for in‐depth explanations of the function and operation of this operational interface. ...

LBC-4000 L-Band Up/Down Converter System Revision 4 Appendix B MN/LBC4000.IOM B.3.4 Gain Offset for Redundant Operations Once redundancy has been enabled, the Ofst (Gain Offset) command, available from the Configure: Conv‐A Atten/Slope submenu, allows gain offset compensation in order for you to match gain between the two converters. Gain Offset is set at installation only. In operation, the normal attenuation setting should be used. The procedure to set the Gain Offset parameters for redundant operation is as follows: Step Task Monitor output signal level on power meter / spectrum analyzer.
