1-3. Installaton of COAX Connector
To connect between the CA-550/550P and CCU-700/700P
with a coaxial cable, instead of a triaxial cable, the TRIAX
connector of the CA-550/550P can replace the supplied
COAX connector. Proceed as follows.
1. Remove the six screws to remove the MIC connector
panel. Disconnect CN1 on the FL-180 board.
3. Install the COAX connector to the connector box with
the screws that were removed in Step 2. Connect the
cable to CN3 on the FL-180 board. Insert until it
clicks.
4. Remove the right side panel, referring to Section 2-1.
Unplug the cable from CN4 on the FL-180 board and
reconnect it to CN5. Insert until it clicks.

Service Overview
c
The power block inside the CA-550/550P will go very hot during operation. If you remove the side panel
and touch the power block, there is some danger to get burned. When you would open the side panel for
check or adjustment, please allow for at least 10 minutes after powering off until the inside cools off.

CA-550P
2-3. Circuit Description
The CA-550/550P mainly consists of the following boards.
MD-103 board
The MD-103 board modulates the luminance signal Y, the
color difference signals R-Y and B-Y. And it selects a
signal to be input/output at GENLOCK IN/PROMPT OUT
connector. And also it quadrature-modulates the Y signal
and SKIN GATE signals with the carrier of 22.5 MHz and
the R-Y and B-Y signals with the carrier of 45 MHz. The
resultant signal is sent to the CCU.
AU-211 board
The CHU/RCP data is input/output from/to the AU-211
board. And processings for the audio signal such as the
INCOM mode switching and gain control are performed.
The received data from the RCP goes through the photo-
coupler and is then send as the RX DATA to control the
camera (CHU), via the 68P I/F connector to the CHU. If
the CCU is connected to the unit, the RX DATA is auto-
matically send to the CCU. As for how to select the
INCOM mode, refer to Section 1-4 “Function of Internal
Switches — AU-211 board”.
TR-90 board
The TR-90 board modulates/demodulates the audio signals
such as the MIC, INCOM and PGM. It also demodulates
the H CONT signal and modulates/demodulates the CHU/
CCU DATA. And it also generates the TONE signal,
piggybacks it on to the CHU DATA and ther modulates
the resultant signal.
DM-98 board
The DM-98 board demodulates the RET VIDEO signal
and also selects an output signal at the RET OUT connec-
tor. The relationships between the switch setting and
output signal are given in Section 1-4 “Function of Internal
Switches — DM-98 board”.
Communication with CCU
The CA-550/550P is not provided with the microcomputer,
so it communicates with the CCU through the camera.
A IIC bus line is equipped for the communication between
the camera and camera adaptor. The IIC bus line is also
used for the interface with the CCU.
2-4. Self-Diagnosis
The CA-550/550P has a diagnosis mode used for self-
diagnosis of every plug-in board. The diagnosis page is
displayed on the viewfinder screen of the camera.
