    MTM400 MPEG Transport Stream Monitor Technical Reference and in Appendix B of this manual. WARNING. To avoid fire hazard, the MTM400 must be installed in the rack only as specified and proper ventilation must be maintained at all times.
  • Page 34: Figure 1-1: Mtm400 Connectors (Shown With Qpsk Interface)

    Rated for indoor use only. Use the following procedure to make electrical, signal, and network connections: After the MTM400 has been mounted in the rack, connect the power cord (provided with the unit) to the power connector on the rear panel. Connect the power cord plug to a properly grounded outlet.
  • Page 35: Table 1-8: Transport Stream Processor Card Connectors

    Table 1-8 summarizes the transport stream, network, and peripheral device connectors; (see the MTM400 MPEG Transport Stream Monitor Technical Reference for more detailed information about each connector and the associated signals).
  • Page 36 The MTM400 is designed to operate in a networked (TCP/IP) environment. The network or system administrator may have already configured the TCP/IP parameters (including the network identity) for the MTM400. If this is not the case, refer to Appendix A: Network Installation for procedures to configure the TCP/IP parameters.
  • Page 37 Check with the transport stream broadcaster for the availability of any font extension set for their transport stream. Because these font extension files are specific to the broadcaster, they are not supplied by Tektronix. The extension sets are provided as TrueType Extension files (*.tte). Any extension sets should be installed using the Private Character Editor, which is supplied as part of the standard Windows installation.
  • Page 38: Powering Up The Mtm400

    After the connections have been made to the unit, all that is required to power up the MTM400 is to apply power. Connect the power cord to a properly grounded outlet. Connect the other end of the cord to the product's power input (see Figure 1-1).
