Titan Electronics Inc NETCOM423 Manuel D’Utilisation

the option of additional protection by “Password”. When a password is 
configured, the NetCom sends the question “Password: “ to the client. 
The user (his application) must first send the password, followed by 
a <CR> character. The password is not echoed to allow usage with 
Telnet on a Monitor. 

 

Also as Raw Client the NetCom 
requires very few parameters. 
Under certain conditions it 
establishes a Raw TCP connection 
to a pre-defined “Destination”. 
Since version 2.0 of the NetCom 
Firmware the Destination can hold 

multiple hosts as targets for a connection. They are entered as a comma 
separated list of DNS names or IP-Addresses. Each destination will 
have a TCP port number, separated by a colon. Instead of a single 
IP-Address or DNS name, a range of IP-Addresses is also valid. This 
range must be followed by the TCP port number, as in 192.168.254.12-
192.168.254.17:2077.

The parameter “Connect” defines if NetCom uses the connections as 

Permanent

, 

Triggered

 or 

DSR

. With 

Permanent

 or 

Triggered

 

any activity on the serial ports establishes the connection, inactivity of 
longer than the “ShortHoldTime” cause NetCom to close the 
connection. 

DSR

 is new since Firmware version 2.0, the 

TCP-connections follow the state of the DSR signal at the NetCom 
serial port. When it becomes active they are established, until DSR 
becomes inactive. At that moment the connections are dropped.
