    AC or DC input voltages. (Installation of the second power sup- ply is an option for the FDC3302.) The presence of proper voltage at the output of each of the two internal DC-DC converters is detected and monitored by the alarm logic and CPU. The outputs of these two power supplies are diode “OR’d”...

  • Page 15: Chapter Two - Basic Installation

    This chapter will guide you through the most basic checkout and physical installation of your FDC3302 Frequency Distribution Chassis. Subsequent chapters and appendices will give you the information needed to configure your installation for the maximum performance in your operating environment.

    Shown with optional Network Port and Dual AC Power Supplies RS-232 Connector This DB-9M connector provides the RS-232 serial I/O interface to the FDC3302. This allows the user to initialize, monitor and control the FDC3302. See Chapter 3 - RS-232 Serial I/O Port Signal Definitions for detailed information.

    If the source(s) of your reference signal(s) has (have) compatible TTL alarm output(s) that you would like to use to force signal input switching on your FDC3302, connect these using coaxial cables to the Disable A and/or Disable B input(s) on the FDC3302. The factory default for the FDC3302 dis- setting is to ignore these inputs.

  • Page 19: Chapter Three - Control And Status Commands

    Chapter Control and Status Commands This chapter describes the FDC3302 control and status commands. The FDC3302 supports com- mands for performing initialization/setup and for monitoring the performance and status of the unit. The serial I/O port physical and electrical characteristics are defined as well.

    A P P E N D I X B After establishing communications with the distribution chassis using the desired port settings, issue the following command to initiate the upload: upload<CR><LF> After issuing this command, you will see the distribution chassis respond with this message: Waiting for download using XMODEM 128 or XMODEM 1K (both with CRC).

  • Page 31: Appendix C - Network Port Option

    Appendix Network Port Option This option allows you to monitor and control your FDC3302 via TCP/IP. Specifically, the telnet, ssh and snmp protocols are supported. The snmp support is MIB II compliant, however no enterprise MIB is implemented. Either telnet or ssh may be used to control and monitor the instrument state, but both protocols cannot be active at the same time.

  • Page 35: Upgrading Firmware

    What You Need To Perform the Upgrade You will need a terminal program which can connect to your FDC3302 via Telnet and supports file uploading using protocols XMODEM 128 with CRC or XMODEM 1K with CRC. These are very common file transfer protocols and should be supported by virtually any terminal program.
