  • Page 9: Operating Precautions

    1. INTRODUCTION Operating Precautions 1.3.1 Power Supply Voltage Confirm the voltage of the power source before you connect the power cord to it. The power requirements of this product are indicated on the rear panel. Only use a power source that supplies a voltage within the operating voltage range and has a frequency of 50/60 Hz.

  • Page 10: Specifications

    SDI signals are switched with relays; all other signals can be switched with electronic switches. The power supplies are redundant. Alarms are generated when errors occur. The LT 4448 is used in combination with the LT 4610 (SYNC GENERATOR) or the LT 4600A (MULTIFORMAT VIDEO GENERATOR) at close distance.
  • Page 11 ● Combining with an LT 4610 or LT 4600A The depth of the LT 4448 is the same as that of the LT 4610 (SYNC GENERATOR) or LT 4600A (MULTIFORMAT VIDEO GENERATOR). This makes it easy to wire and operate the devices when you combine them.

    4. HOW TO USE 4.5.1 Setting Method When one of the slide switches on the DIP switch is in the ON position, that switch is ON. When a slide switch is in the opposite position, it is OFF. Use an item that has a fine tip, such as a pen or a pair of tweezers, to move switches between the ON and OFF positions.
  • Page 28 4. HOW TO USE The channels that you can apply signals to differ depending on the type of input signal as shown below.

  • Page 33: Setting The Fault Detection Level (User-Defined)

    Below is an example of a procedure to apply signals to channel 1 using user setting 1. Set DIP switches SW1 and SW3 of CH-1 (S2) to ON. Restart the LT 4448 to apply the new settings. Connect between the input signal and PRIMARY an attenuator with an appropriate attenuation (3 to 6 dB) for detecting faults.

  • Page 34: Setting The Operation Mode, Standby Time And Fault Information

    ● Setting the Standby Time You can select the length of time that the LT 4448 waits from the time that it turns ON to the time that it begins operating. Select a setting that is appropriate for the rise time of the system signal source that you are connected to.
  • Page 35 4. HOW TO USE ●Setting the Fault information You can set the contents of the fault information to be output from the remote connector on the rear panel. If set to FAULT Only, when a fault is detected in PRIMARY or BACKUP, the fault indicator transmits a high-level signal and the positive and negative fault indicators conduct current.

  • Page 36: Ch1 To 11 Signal I/O

    4. HOW TO USE Ch1 to 11 Signal I/O Apply the primary signal to PRIMARY1 to 11 and the backup signal to BACKUP1 to 11. The input signal impedance is 75 Ω. Terminate the output connectors at 75 Ω. (The signal that is not selected with the front-panel SYNC SOURCE setting is terminated internally at 75 Ω.) Depending on the front-panel SYNC SOURCE setting, the primary or backup signal is transmitted from OUTPUT1 to 11.
