How to access a RAM
drive from a PC?
A PC can access a RAM drive using the FTP client tool.
The initial values of V440-F are as follows.
Example: When using Internet Explorer to access.
1. If the IP address is the default, enter
ftp://192.168.188.2/imagesd 0/images/ in the address bar to connect.
2. Enter your account and password.
3. Download the file saved in the RAM drive to your PC.
Parallel communications
timing chart
The parallel output signals, OUTPUT1/OUTPUT2/OUTPUT3, can change those roles by the output condition settings.
The default is that those are turned on when all are No-Read.
WebLink - Gear icon -
Advanced - I/O - OUTPUT1 parameters - Output On
Additionally, a timing to turn off can also be adjusted using the following setting.
WebLink - Gear icon -
Advanced - I/O - OUTPUT1parameters - Output Mode
When you want to detect a timing that the output is changed, set the output condition for one of
OUTPUT1/OUTPUT2/OUTPUT3 to
In Read Cycle .
According to the setting, it turns on in a period from detecting a trigger, reading, and end of output.
For example, the following describes a timing chart in a case of a setting below.
• Output On
OUTPUT1 In Read Cycle
OUTPUT2 Match or Good Read
OUTPUT3 Mismatch or No-Read

How to estimate an
exposure time when
reading a moving
symbol?
A moving amount of a symbol during exposure should be 1/10 or less of the cell size (for barcode, narrow bar width).
When a cell size is C [mm] and a line speed is L [mm/s], use the following formula to get the exposure time S.
S
≤ 0.1×C/L
For example, When a cell size is 0.3 [mm] and a line speed is 300 [mm/s], the exposure time should be 100 [ μ s] or less.
0.1×0.3 [mm]/300 [mm/s] = 100 [ μ s]
