Explanation

Special settings related to the FTP client, LPR, and SMTP are entered.Set these items
as necessary.

• Turning ON/OFF the FTP Passive Mode

Turn this function ON when using this instrument behind a firewall

that requires the

passive mode. The default setting is OFF.
* A firewall is furnished on a system that has security features. It prevents intrusion

from the outside into the network system.

• Setting the LPR Timeout Value

This instrument closes the connection to the printer if there is no response from the

printer for a certain period of time (timeout time) while it attempts to access the printer.

You can set the timeout value in the range of 0 to 3600 s. The default value is 15 s.

• Setting the SMTP

Timeout Value

When a mail server is accessed from this instrument and connection cannot be

established after a certain period of time (timeout time), this instrument decides that
the connection to the mail server is not possible and closes the connection.

You can set the timeout value in the range of 0 to 3600 s. The default value is 15 s.

* SMTP (Simple Mail Transfer Protocol) is a protocol that resides above the TCP/IP

layer and is used by the e-mail transmission system.
