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.

Hybrid Routing

To implement the hybrid routing ensuring the high quality signal characteristics, the sixteen JK-66 boards are mounted on each output board of the DVS-128 series. The JK-66 board is a connection switch board that turns on and off the matrix input (128 input lines) in each output board. The JK-66 boards are set to ON when the DVS-128 is shipped from the factory. When setting up both analog audio and analog video system in the DVS-128, the JK-66 boards of the input channel to which the analog video signal is impressed should be removed from the matrix input block of the analog audio output board. When setting up either analog audio or analog video system, it is not required to remove the JK-66 boards. When installing the DVS-128, remove the JK-66 boards accordance with the desired system configuration in order to prevent occurrence of interference between the different signal formats. Each of the JK-66 board contains the switches for eight channels as shown below. The sixteen JK-66 boards configure a switch for 128 channels. The JK-66 boards are located near the connectors (from which connection to the mother board is established) of each output board. The four JK-66 boards are located to the input channels of 1 to 32, 33 to 64, 97 to 128 and 65 to 96 when viewed from the left.

S4 (A-6): 8-pin DIP switch

Bit 1: SYNC/ASYNC switch

This switch selects whether the input video signals are switched synchronously or asynchronously with the reference video signal that is input to the REF IN connector. The DVS-128 operates asynchronously even if this switch is set to SYNC, unless the reference video signal is input to the REF IN connector. In this case, this is detected as an error.

OPEN (upper position): Asynchronous mode CLOSE (lower position): Synchronous mode

Bit 2: S/P switch

This switch is used to selects whether the DVS-128 operates as a primary station or a secondary station when it is connected to the S-BUS data link with the REMOTE 1 connector.

OPEN (upper position): Operates as a primary

station

CLOSE (lower position): Operates as a secondary

station

S7001 (G-8): Clamp mode select switch 8-pin DIP switch

The input signals are clamped in units of eight channels

using the following modes.

. Self mode

The respective input signals are clamped by their own signals. This mode is valid for all video signals except

for the color difference signal.

. Reference mode

The respective input signals are clamped by the clamp signal that is generated from the reference signal. This mode is valid only when the input signal is sync-locked with the reference signal. The reference signal needs to be input for this mode.

. Direct mode

The DC levels of the respective input signals are maintained as they are and are output. This mode works effectively even when a signal having no SYNC signal

such as a color difference signal is input. This mode can be used for all types of video signal. When the HDTV signal is used, be sure to select this mode.

8 bits are grouped into the following four blocks. Each block selects the clamp mode individually in units of eight channels.

ISR (Interactive Status Reporting) is a Sony application program that was developed to intensively monitor and control the operation status of equipment used in a broadcasting station or production or the contents of a generated error on the monitor screen of one computer. The DVS-128 corresponds to this ISR. This section describes the information required when the DVS-128 is connected to ISR. For more details of ISR, refer to the manual supplied for an application program or the optional CAT Protocol Manual.

4-2. Cleaning

Be sure to turn the power switch to the OFF position and disconnect the AC power from AC outlet before starting any works.

This section explains how to clean the periodical inspection parts.

4-2-1. Filters

Clean the filter at the back of the front panel once every two months becasue it is apt to catch dust.

Temperature inside the DVS-128 increases when ventilation holes are blocked as dust adheres to filter. Touching inside the DVS-128 while it is hot, can result in physical burning. Clean the filter periodically. (Once every two months.)

4-2-2. Fans

The temperature in the unit increases when dust adheres to the opening block of fans and when the airflow is disturbed. This may badly influence the performance and life of the set. It is recommended to clean the fans every one month.

1. Remove dust on the fans and finger guards using a vacumm.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer :

Check the metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 3.5 mA. Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.

2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 5.25 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 20 V AC range are suitable. (See Fig. A)
