Chapter 7. SERIAL-BASED REMOTE PRODUCT
MANAGEMENT
7.1 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.
1. To proceed with Serial‐based Remote Product Management, assumptions are made that:
• The LBC‐4000 is operating with the latest version firmware files.
• The LBC‐4000 is connected to a user‐supplied Windows‐based PC as follows:
o The PC serial port is connected to the LBC‐4000 rear panel ‘J1 | COM1’ port with a user‐supplied serial cable.
o The PC is running a terminal emulation program (for operation of the LBC‐4000 serial remote control interface).
2. See Chapter Sect. 3.2.2.4 J1 | COM 1 (EIA‐485/232) Interface Connector (DB‐9F) for the serial interface connector pinout
information.
