Zoom/Focus Lens Control
Zoom/Focus Lens Position Range
• Optical zoom lens position range
Æ000 hex ~ 940 hex
• Focus lens position controllable range
Æ17a hex ~ 481 hex
(It is not specified)
• Digital zoom position
Æ00 hex ~ EA hex
Zoom Lens Speed Mode
• Normal(Slow) Zoom Mode
: Zoom lens speed is slow.
• Quick Zoom Mode
: Zoom lens speed is faster than Slow
Zoom Mode.
Zoom Trace Mode
Zoom Trace : If the zoom lens moves, the
focus lens also moves. The focus lens will be
moved to a certain calculated position.
So, the picture will be focused while the zoom
lens moves to the target zoom position.
• Slow(Normal) Zoom Trace Mode(SZT)
: It is a zoom trace mode that the zoom
speed is Slow(normal).
• Quick Zoom Trace Mode(QZT)
: It is a zoom trace mode that the zoom
speed is Quick.
• Non Zoom Trace Mode(NZT)
: When the zoom lens moves, the focus
lens doesn’t move, so the picture will not
be focused while the zoom lens moves to
the target position.
One Shot Focus
• The camera starts the auto focusing
action only one time.
• When the One Shot Focus Command is
sent, the focus lens moves to adjust the
focus for the subject.
Auto zoom
• The zoom lens have a repeated action in
a certain zoom range.

A(V)N(P)120
’ s Protocol Version 1.1
Communication Format
A(V)N(P)120’s RS-232C
Communication Format
Communication between camera and user is
available by using RS-232C.
Parameter of RS-232C
• Baud Rate : 9.6kbps
• Start bit : 1
• Stop bit : 1
• Data bits : 8
• None Parity
• Flow control : XON/XOFF,RTS/CTS is
not supported.
Packet Structure
The basic unit of AN200’s communication is
called ‘PACKET’.
All bytes of the packet are ASCII format.
The first byte of the packet is called ‘Header’.
And the second and third bytes are ‘ID’ of
the camera. And the forth and the fifth
bytes are ‘Command Message’. And from
the sixth to the ninth bytes are ‘Command
Option’.
And the last two bytes are ‘Check sum’ of
the packet.
The check sum is sum of 9 bytes(byte0~byte8).
• The header must be ‘*’.
• All bytes of the packet must be a Capital
Letter.

A(V)N(P)120
’ s Protocol Version 1.1
Bytes of a packet
• Byte 0 : Header
It must be the ASCII code ‘*’ (2A hex)
• Byte 1 : High character of camera ID
Byte 2 : Low character of camera ID
Ex) current camera ID : 43 decimal
43 decimal = 2B hex
Byte 1 : ASCII code ‘2’(32 hex)
Byte 2 : ASCII code ‘B’(42 hex)
• Byte 3, Byte 4 : Command
• Byte 5 ~ Byte 8 : Option of command
• Byte 9 : High byte of check sum
Byte 10 : Low byte of check sum
Response from the camera
If the command packet is transmitted to the
camera accurately, the camera will send the
‘response packet’. If the camera doesn’t
receive the right command packet, it will not
send any response packet.
Check Sum Method
The value of check sum is calculated as
follows.
Check Sum = Byte0 + Byte1+ … + Byte8
Ex) if ID = 43 d (2B hex), command = 75 hex,
command option = 0000
command byte0~byte8 : * 2B 75 0000
ASCII format
: 2A 32 42 37 35 30 30 30 30
Sum = 2A+32+42+37+35+30+30+30+30
= 1CA hex
So, the Check Sum = CA
So the complete command packet
= * 2B 75 0000 CA
Response Time
Most of the response packet will be transmitted
as soon as the camera received the command
packet.
This time is more than 2ms.

A(V)N(P)120
’ s Protocol Version 1.1
Communication Time Delay
When transmitting 1 packet(11 bytes), keep 2
milli-seconds waiting time between bytes.
Advice for communication
• If the command packet is transmitted
only 4 bytes, then the camera will wait
for remain 7 bytes continuously.
At that moment, if a new packet is
transmitted to the camera, the previous 4
bytes will be ignored.
• If the camera doesn’t send any response
packet, there should be some troubles in
communication line or any other
communication condition.
• If the camera response mode is Skip
Command response packet mode, then
the camera will not send Command
response packet. Even if the response
mode is Skip Command response packet
mode , the Data response packet will be
transmitted to PC.
After transmitting the first packet, wait for
25 ms to transmit next command packet.
• Byte delay time > 2ms
• Packet delay time > 25ms
*) Byte delay and Packet delay is a time delay
for stable communication.
