Transport Stream Processor card internally. 1-10 Table 1-7 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 25 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 26 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 27: 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).

Page 35 This section provides an overview of the basic operation of the system; details and background material are found in the Reference section. The monitoring activity of the MTM400 can be observed in three ways: Options are available to the RUI and the WebMSM to upgrade the monitoring from simple conformance checking to full diagnostic capability using license keys.
Page 36: Local Indicators
Operating Basics Local Indicators The MTM400 is an MPEG monitor for use in remote situations and does not have a local graphical user interface display. However, a local interface, consisting of four front-panel LEDs, can assure you that the MTM400 unit is functioning.
Page 37: Remote User Interface
Remote User Interface The Remote User Interface (RUI) allows you to configure and monitor the MTM400. The RUI can be run on any personal computer (client PC) that meets the minimum specifications (refer to MTM400 MPEG Transport Stream Monitor Technical Reference) and that has access to the MTM400 unit.
