# 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 0.5 mA. Leakage
|
|
current can be measured by any one of three
|
|
methods.
|
|
|
|
|
|
1. Acommercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments.
|
|
|
|
2. Abattery-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 0.75 V, so analog meters must have an accurate low- voltage 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 2 V AC range are suitable. (See Fig. A)

# 2-3. COAX CONNECTOR
|
|
|
|
|
|
The COAX connector (BNC type) can be used for connection
|
|
between the CCU and the CA with a BNC cable instead of a
|
|
triaxial cable. In this case, supply the power source from
|
|
outside to the CA side.
|
|
And for the CA side, it is needed to modify the TRIAX
|
|
harness to the COAX harness.
|
|
For the CCU, the following modification is required.
|
|
Disconnect the RF cable from the CN3 on the IO-141 board
|
|
and reconnect it to the CN4.

# 3-3. CIRCUIT DESCRIPTION
|
|
|
|
|
|
## CT-181 board
|
|
|
|
|
|
CT-181 board employs RF system circuit that is consists of
|
|
RETURN VIDEO modulation circuit and PROMPT VIDEO
|
|
modulation circuit (It becomes AUX VIDEO demodulation
|
|
circuit by switching.) and microcomputer system circuit that
|
|
controls the system.
|
|
|
|
|
|
Microcomputer system circuit section :
|
|
The program is written in the ROM (C1022) that is inserted
|
|
to socket (CNI 1). ROM of built-in microcomputer is not
|
|
used. Input and output of control signals between each board
|
|
in CCU (included in COU) and each board are performed by
|
|
serial data of 16 bit via YO EXPANDER (1C1028). There are
|
|
four communication channels with outside. The SCI-1 and
|
|
SCI-2 built-in microcomputer communicate with CA (via
|
|
modulation and demodulation circuit ) and RCP (via RS-232C
|
|
driver). The external SCI (1C1024 and 1025) communicates
|
|
with command link (RS-232C-1 and RS-232C-2 on the rear
|
|
panel).
|
|
|
|
|
|
The RF system circuit section :
|
|
RETURN VIDEO modulation circuit frequency-modulates
|
|
the input signal (VBS) from RETURN VIDEO 1 or 2, and
|
|
sends to the CA. Change of RETURN VIDEO 1 or 2 is
|
|
switched by RETURN 1! and 2 changing switch on the CA.
|
|
The PROMPT VIDEO modulation circuit amplitude-
|
|
modulates the input signal (VBS) from PROMPT VIDEO on
|
|
the rear panel, and sends to the CA. The PROMPT VIDEO
|
|
modulation circuit becomes AUX VIDEO demodulation
|
|
circuit by switching S2002 and connecting RF coaxial cable to
|
|
CN3 and CN8. (lt is needed to change on the YD-25 board of
|
|
CA.)
|
|
Demodulated AUX VIDEO is outputted from PROMPT
|
|
VIDEO on the rear panel.
|
|
|
|
|
|
## AA-90 board
|
|
|
|
|
|
This board demodulates the RF signal of MIC1, MIC2,
|
|
INCOM, CAM DATA and TONE sent from the CA,
|
|
modulates a PGM signal, the INCOM signal and control data
|
|
send to the CA. And also, this board switches the INCOM
|
|
line, and switches the input /output of each audio signals.
|
|
|
|
|
|
3-4
|
|
|
|
|
|
## YD-26 board
|
|
|
|
|
|
YD-26 board demodulates Y, R-Y, B-Y, CAM SYNC and
|
|
SKIN GATE. This circuit consists of cable length detection
|
|
circuit, cable length compensation circuit and these
|
|
demodulation circuits. The cable length detection detects
|
|
from amplitude of Y modulated wave. In accordance with
|
|
this, the cable compensation circuit compensates the
|
|
amplitude and phase matching as cable length to modulated
|
|
wave of Y or differential signal. After that, they are
|
|
respectively demodulated in demodulator circuit.
|
|
|
|
|
|
## ES-20 board
|
|
|
|
|
|
This board produces VBS and RGB signal from the Y, R-Y,
|
|
and B-Y signals sent from the YD-26 board, switches these
|
|
signals, and outputs them as WF and PIX signals. This
|
|
board also generates each sync signal and color bars signal.
|
|
|
|
|
|
## AU-234 board
|
|
|
|
|
|
This board inputs and outputs an INCOM signal on the front
|
|
panel, displays tally signals, and turns on and off the power
|
|
of camera.
|
|
|
|
|
|
## 10-140 board
|
|
|
|
|
|
This board mixes the RF signal between CA and CCU with
|
|
the power of the camera.
|
|
|
|
|
|
## SDI-44 board (DXBK-701)
|
|
|
|
|
|
This board converts the analog video/audio signals into
|
|
digital signals and outputs them as SDI signals.
|
|
|
|
|
|
Video signal processing :
|
|
Y, R-Y and B-Y signals sent from the ES-20 board are
|
|
converted from analog to digital and subject to the double
|
|
over-sampling process on the digital filter IC308.
|
|
|
|
|
|
Audio signal processing :
|
|
MIC1 and MIC2 signals sent from the AA-90 board are
|
|
converted from analog to digital and subject to 64 times
|
|
over-sampling process on IC904 and then subject to time-
|
|
base compression on IC404.
|
|
|
|
|
|
These digital video signals and the time-base compressed
|
|
digital audio signals are mixed on IC413. After that, the
|
|
parallel data is converted to serial data on IC702 and output
|
|
from this board.
