Quick stops, excessive force and uneven surfaces may cause the product and cart combination to overturn. [. . . ] The purpose of the OBM100 is to provide a one way data channel from the headend to a universe of set top boxes that are being served by the headend. Usually program guide and conditional access control information will be sent through this channel. First of all it accepts an ASI transport stream from the SCT2X4 data output connector. The OBM100 takes this low data rate stream and without making any changes to the data, outputs the data through an Ethernet connection to the headend control PC. After the headend PC constructs a complete data stream for the set tops, derived from the satellite delivered data and from locally generated data, the resulting stream is output from the headend control PC back to the OBM100 on the same Ethernet cable that is passing the satellite delivered data in the other direction. The OMB100 accepts this incoming data and performs its second function ­ transmitting this data stream to the set top boxes. The OBM100 generates a QPSK modulated signal, modulated by the data stream from the headend controller, at a data rate of approximately 3 Mbps. This signal is upconverted to any operator selected frequency between 70 and 130 MHz for transmission throughout the cable plant. INSTALLATION AND MOUNTING NOTES This equipment is designed to be installed in a standard 19" rack. When the unit is mounted above or below other rack mounted equipment, a 1U space (1. 75") should be left between the unit and the other equipment to allow ambient air flow between the units. Connect a cable from the OBM100 Ethernet connector to the Ethernet connector on the PC based headend controller. Connect each of the four ASI INPUT connectors of the OBM100 to the ASI DATA connectors of the Drake SCT2x4 Transcoders in the system.

ENTER F1 F2 F3 F4 buttons will not change any parameter setting. F3, Up and Down Buttons ­ Use the up and down arrow buttons to change the value of a viewed parameter setting. The unit must be in the adjust mode in order for these buttons to become active for changing a parameter setting. F4, ENTER Button - Use the ENTER button to enter the adjust mode or to save and load a new setting or settings after adjustment. Hold for approximately 2 seconds until a flashing "^" appears in the upper right hand corner of the display to enter the adjust mode. After entering the adjust mode, momentarily pressing the ENTER button again will load and save any settings that may have been changed using the UP and DOWN buttons, and will exit the adjust mode. Note that the adjust mode cannot be entered from the firmware version number or MAC number screens. F1, LCD Display ­ This display presents the selected menu screen and the parameter settings. When not in adjust mode the firmware version number is displayed on the top line, and the unit's IP address, if programmed, is displayed on the bottom line. If DHCP has been enabled but the unit has not been connected to an appropriate DHCP enabled PC based controller, "DHCP. . . . . . . . . . . . " will be displayed instead of an IP address. Pressing the UP or DOWN buttons cycles the display through the firmware version screen, the data rate screens, and the MAC number screen. [. . . ] The unit must be sent to the following address: Service Department R. L. Be sure to include your street address which will be needed for UPS return. UPS Surface (Brown Label) takes 7-10 days to reach us depending on your location, Blue takes 2-3 days. Red is an overnight service. Send the unit in a way that it can be traced if we can't verify receipt of shipment. [. . . ]
