1-5. Cross Point Switching Timing

1-5-1. Selection of the Cross Point Switching Timings

Cross points of all the audio and video signals are switched at the timing that is synchronized with the reference input signal. The reference input signal can be selected for each matrix and OUTPUT board. Using this function, the cross points can be switched at the different timings that are synchronized to the difference reference input signals in units of circuit board. The desired input reference signal can be selected by the slide switch on the respective matrix and OUTPUT board. Either position A or B can be selected. Relation between the selector switches and the matrix is described as follows.

The REF A signal must be input to the DVS-128 in order to enable the cross point switching locked to the reference signal.

1-5-2. Audio Clock Signal

The clock signal that is extracted from either input word sync A or input word sync B, is used for audio signal processing in the DVS-128. When any word sync signals are not input, the DVS-128 operates on the clock signal that is synchronous with the input reference signal of the video signal.

Either REF A or REF B can be selected in each circuit board as the reference signal. It should be noted that the same reference signal must be selected for both input and output of any audio signal processing board. (both analog and digital audio processing boards.)

1-6-1. Redundant Power Supply System

The DVS-128 is equipped with the backup power supply unit (BKDS-12891) in addition to the standard power supply unit. Therefore the power supply system is duplexed, the DVS-128 can realize the high reliability. Either of the standard power supply unit and the backup power supply unit can support the full load of the DVS-128 respectively that assures the stable operation even when either one of the power supply lines fails, or when either one of the power supply units becomes defective.

DC outputs of the redundant power supply system are connected in the logic-OR connection using diodes which supplies +5.6 V/_ 5.6 V to the power bus line of the mother board of the DVS-128. The +5.6 V/ _ 5.6 V powers are used in the respective boards where the required power supply voltages are generated by either series regulator or DC-to-DC converter. In addition, the redundant power supply system has the unique function (current balancing function) of sharing the loads after balancing them. This function assures the highly reliable power supply operation with sufficient margin when compared with the operation on a single power supply unit.

The DVS-128 can be equipped with the optional backup CPU board (BKDS-12890) in addition to the CPU board (CPU-275) (called CPU-A hereafter) that is installed in the slot: CPU-A of the DVS-128. The CPU board can be duplexed by installing the backup CPU board (called CPU-B hereafter) into the slot: CPU-B of the DVS-128. The CPU-A performs control over the entire system of the DVS-128 in normal condition. If the CPU-A fails, the CPU-B backs up the full function of the CPU-A. If either the CPU-A or CPU-B fails, the power status LED on the front panel turns on in red and an alarm is triggered in the control terminal. It facilitates preventive maintenance.

Note on connection

. For the routing switcher that is used as a primary station, set the P/S switch on the CPU-275 board to

“P”.

. The number of secondary stations that a primary station can control is 253 (maximum). . The number of secondary stations that can be connected to one S-BUS line is 128 (maximum). . The cable length of one S-BUS line is 500 m (maximum) (when a 5C-2V cable is used). . The T-type bridge installed in the last machine of an S-BUS line and the unused REMOTE1 connector

of each switcher are necessarily terminated using a 75 Z terminator.

. Only one REMOTE 1 connector of a routing switcher in a secondary station can be used.

How to use T-type bridge

DVS-128 has a B-type T bridge. During connection, use a coaxial cable of less than 50 cm as shown below.
