OnCell G3111/G3151/G3211/G3251 Series User’s Manual Serial Port Operation Modes
8-6
ATTENTION
When Max connection is greater than 1, the OnCell G3111/G3151/G3211/G3251 will use a multi
connection application (i.e., 2 hosts are allowed access to the port at the same time). When using
a multi connection application, the OnCell G3111/G3151/G3211/G3251 will use the serial
communication parameters as defined here in the web console, and all hosts connected to the port
must use identical serial settings. If one of the hosts opens the COM port with different serial
settings, data will not be transmitted properly.
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.
Allow driver control (default=Disable): This option determines how the port will proceed if
driver control commands are received from multiple hosts that are connected to the port. If
Disable is selected, driver control commands will be ignored. If Enable is selected, control
commands will be accepted, with the most recent command received taking precedence.
Destination address 1 through 2 (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=63950): This is the TCP port number assignment for the remote host/server. It
is the port number that the OnCell G3111/G3151/G3211/G3251s serial port uses to establish
connections with a remote host/server. To avoid conflicts with well known TCP ports, the default
is set to 63950.
Command port (default=63966): The Command port is the COM port for listening to SSDK
commands from the host. In order to prevent a COM port conflict with other applications, the user
can set the Command port to another port if needed.
ATTENTION
Up to 2 connections can be established between OnCell G3111/G3151/G3211/G3251 hosts.
Port 63950 might be blocked by a firewall. You should make sure the port is NOT blocked before
you start using it.
ATTENTION
The destination IP address parameter can be the IP address, domain name, or the name defined in
the host table.
