The RS232 Control Box allows the user to control the Observation
System from another location or through a PC. With the right
additional equipment, this accessory allows the user to perform most
functions of the Observation system (switching to other camera or
view mode, action command etc.). In addition, it has a local standard
video and audio output from the system monitor, and provides a local
alarm relay output.
Applications include remote video transmission and system control
(specific third party equipment needed) and PC control of system
modes.
Installation
Remark: When the system configuration is altered, the system monitor
needs to check and memorise the configuration of the cameras and
accessories connected to its inputs. This is done automatically when
the power is switched on. Use the power switch to switch off; only
operating the power save key is not sufficient. If switching off is
impracticable, use the auto install option of the system monitor's install
menu.
Power on sequence:
First power on the RS232 control box and then the Observation
System.

Mounting the box
1 Loosen the screw holding the cover and remove the cover.
2 Remove the circuit board
3 Fasten the bottom plate of the box with two screws.
4 Fit the circuit board.
5 IMPORTANT: Adjust the settings of the circuit board switches to
configure the box according to your system. See section 'settings'.
6 Fit the cover and secure the screw holding it.
7 Now make the connections. See section 'possible configurations'
for the correct connections and the setting of the internal 'slide
switches'.

System cable
For the interconnections between the monitor, accessories and camera,
a system cable is supplied. For an optimum picture and sound quality,
you should always use 4-wire dual twisted-pair cable when extending
the connection (max. 300m/900ft). The cable and plugs are available in
the hobby and professional trade. Fix the connectors to the cable
corresponding to the f igure below.
Caution: The plugs used for the observation system have the same
dimensions as standard telephone plugs.
Never connect the security system with telephone equipment!
External power supply
The box needs to be powered locally with a mains power supply which
is included in the product.

Slave in line switch (6, 7)
With these switch you can enable a slave monitor on the system cable
output of the RS232 Control Box.
There are two possibilities:
• No slave
There is no slave monitor connected after the RS232 Control Box
(seen from the system monitor)
• Slave
There is a slave monitor connected after the RS232 Control Box (seen
from the system monitor)
Audio level switch (11)
With this switch the audio output level can be selected. There are two
possibilities: High and Low level.
Remark: The slave in line switch is normally set to the "NO SLAVE"
position.

Possible configurations
This section shows the system configurations which are possible with
the RS232 Control Box.
1. Remote video transmission with control capabilities (third
party equipement needed)
The Observation System can be connected to a video transmission unit
for off-site viewing of the system video. When using the RS232
Control Box with selected third party video transmission equipement,
the Observation System can also be controlled from the remote site,
allowing the user to switch to different cameras and perform local
actions like opening doors.
Remark: For this application the video transmission unit needs to
support the Philips RS232 Control Protocol.
2. Using PC as slave monitor with control capabilities (third
party software needed)
The Observation System can connect directly to a PC for control and
display. The RS232 interface of the RS232 Control Box can connect to
the serial port of a PC for control of the Observation System.
For also displaying the system video on the PC, a PC with a analogue
video input (video grabber board) is needed.
When the appropriate software is loaded on the PC, the video and
audio of the Observation System can be shown on the screen and the
functionality of the system can be partly controlled.
Remark: For this application specific third party software is needed

3. Additional alarm output with short activation time
The Observation System has an alarm output (on the back of the
monitor) with a long activation time (typically 15 minutes, see system
user manual). For some applications this can be too long. The alarm
output activation time of the RS232 Control Box is 30 seconds,
solving the problem in most cases.
4. Connecting a standard monitor as slave monitor
Using the video and audio outputs on the RS232 Control Box, a
standard video monitor or TV can be used as a slave monitor output,
while still having the advantage of using the system cable to cover
large distances.
