    If the source(s) of your time code signal(s) has(have) compatible TTL alarm output(s) that you would like to use to force signal input switching on your TDC3303, connect these using coaxial cable(s) to the Disable A and/or Disable B input(s) on the TDC3303. The factory default for the TDC3303 dis- setting is to ignore these inputs.

  • Page 19: Chapter Three - Control And Status Commands

    Chapter Control and Status Commands This chapter describes the TDC3303 control and status commands. The TDC3303 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 TDC3303 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.

    What You Need To Perform the Upgrade You will need a terminal program which can connect to your TDC3303 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.
