OnCell G3111/G3151/G3211/G3251 Series User’s Manual Serial Port Operation Modes
8-14
ATTENTION
Inactivity time is ONLY active when Connection Control (see below) is set to Any
character/Inactivity time.
Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple
hosts are connected and one or more of the hosts stops responding as the port is transmitting data. If
you select Disable, the port will wait until the data has been transmitted successfully to all hosts
before transmitting the next group of data. If you select Enable, the port will ignore the host that
stopped responding and continue data transmission to the other hosts.
Destination address 1 through 4 (default=None): Specifying an IP address allows the OnCell
G3111/G3151/G3211/G3251 to connect actively to the remote host. At least one destination must be
provided.
TCP port (default=4001): This is the TCP port number assignment for the serial port on the OnCell
G3111/G3151/G3211/G3251. It is the port number that the serial port uses to make a connection,
and that serial port must use to contact the other devices. To avoid conflicts with well known TCP
ports, the default is set to 4001.
ATTENTION
Up to 4 connections can be established between the OnCell G3111/G3151/G3211/G3251 and
hosts. The connection speed or throughput may be low if any one of the four connections is slow,
since the one slow connection will slow down the other 3 connections.
ATTENTION
The Destination IP address parameter can be the IP address, domain name, or the name defined
in the host table. For some applications, the user may need to send the data actively to the remote
destination domain name.
Designated local port 1 through 4 (default=5010 through 5013): Use these fields to specify the
designated local ports.
Connection control (default=Startup/None): This setting determines the parameters under which a
TCP connection is established or disconnected. The different options are given in the following table.
In general, both the Connect condition and Disconnect conditions are given.
