2. Data Multiplex/De-Multiplex circuit
All incoming/outgoing data or signals of the camera should pass the Slip Ring.
However, the Slip Ring has a limited number of signal paths so that the data
and signals should be multiplexed. Once they are multiplexed, they must be
de-multiplexed. The IC37 is used for this purpose.
The IC1 (CPU) on the Digital Board sends out RS485TxD from pin29.
The RS485TxD signal includes RS485 and 2 Alarm Output signals.
The RS485TxD signal enters to pin6 of IC18 on the Servo Board via
CN4,pin11 (Digital Board)
Æ CN1, pin14 (Servo Board).
The RS485TxD is output from pin8 of IC18 then appeared at pin2 of CN3
named as DOUT. The DOUT signal will be transferred to the Communication
board through the Slip Ring.
The signal at CN3, pin1 is a multiplexed signal named as DIN from
Communication Board via Slip Ring. This signla includes RS485, 4 alarm
inputs, Dip switch informaiton and Line Pulse (LP).
This signal (DIN) enters to pin4,6,8 of IC37.
The RS485RxD signal is output from IC37 pin2,pin20. The RS485RxD
signal includes RS485 signal, Alarm input signals and the Dip switchi
information. The RS485RxD signal is supplied to CN1, pin15.
The LP signal is made by IC35, IC36 and IC34. Then PL signal is output from
pin4, IC34 and is supplied to CN1,pin15..
The RS485RxD signal is supplied to IC1, pin30 via CN1,pin15
ÆCN4 pin10.
The LP signal is supplied to IC1, pin18 via CN1,pin12
Æ CN4,pin13.
3. Power Regulator
There are 2 power switching regulators on the Servo Board, IC12 and IC16.
The IC12 generates the DC power for the Pan and Tilt Motors.
The IC16 generates the DC power for the whole camera circuits.

Communication Board:
There are several input signals to the camera such as RS485 signal, 4 alarm
input signals and Dip switch setting data. And there is a Line pulse signal from
the power board.
Also there are output signals from the camera such as Video output signal,
RS485 signal and 2 alarm output singals.
The above these signals pass the Communication Board.
The Communication Board is a kind of interface board between inside and
outside camera.
1. Singal flow of input signals
The RS485 signal is supplied to CN2, pin12,pin13. They enter to pin11,pin12
of IC7 (RS485 Converter). The RS485 is output from pin1 of IC7, then enters
to Pin22 of IC14 (CPU).
The 4 alarm input signals are supplied to CN3, pin5-9. Then these signals
enter to IC14 (CPU).
The Dip switch setting data is supplied to CN2,pin1-pin8. These signals enter
to IC14. The 4 alarm input signals, the Dip switch setting data and RS485
signal are mixed at IC7. The mixed signal is output from pin28, IC7 (CAM TxD)
and is supplied to pin5, IC7.
The Line Pulse (LP) signal is supplied to CN5,pin3 from the power board.
The LP signal is supplied to pin1, IC7 and is mixed with CAM TxD signal..
The mixed signal is output from pin3 of IC7 and is supplied to pin6 of
IC19.(Buffer) The buffered signal is output from pin7 of IC19 and is supplied
to CN7, pin3. Then this signal is transferred to CN3,pin1 on the Servo Board
through the Slip Ring.
2. Signal flow of output signals
From pin14 of CN1 on the Servo Board, the RS485TxD signal enters to pin8
of IC18. The RS485TxD signal is output from pin of IC18 named as DOUT
then enters to the Slip Ring via CN3, pin2.
.After transmitting the Slip Ring, DOUT signal is appeared at CN7, pin4 on the
Communication Board then enters to the IC14,pin29 (CPU).

The RS485 and alarm signal will be separated in IC14. The RS485 is output
from pin23 and alarm signal is output from pin54, pin55.
The RS485 enters to IC7 (Converter) and the output signal is supplied to CN2,
pin10,pin11.
The alarm signals are output from pin54, pin55 of IC14 and are supplied to
CN3, pin10,pin11.
