OnCell G3100 Series Configuring Serial Port Operation Modes
8-10
Max connection (default=1): This field is used if you need to receive data from different hosts
simultaneously. When set to 1, only a single host may open the TCP connection to the serial port. When set to
2, the specified number of hosts may open this port at the same time. When multiple hosts establish a TCP
connection to the serial port at the same time, the OnCell G3100 will duplicate the serial data and transmit it
to all the hosts. Cellular or Ethernet data is sent on a first-in first-out basis to the serial port when data comes
into the OnCell G3100 from the Cellular or Ethernet interface.
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.
Secure (default=Disable): If you select Enable, data sent through the Ethernet will be encrypted with SSL.
TCP port (default=4001): This is the TCP port number assignment for the serial port on the OnCell G3100. It
is the port number that the serial port uses to listen to connections, and that other devices must use to contact
the serial port. To avoid conflicts with well known TCP ports, the default is set to 4001.
Command port (default=966): The Command port is the TCP port for listening to SSDK commands from the
host. In order to prevent a TCP port conflict with other applications, the user can set the Command port to
another port if needed.
Packet length (default=0): The Packet length setting refers to the maximum amount of data that is allowed
to accumulate in the serial port buffer before sending. At the default of 0 for packet length, no maximum
amount is specified and data in the buffer will be sent as specified by the delimiter settings or when the buffer
is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it
reaches the specified length.
Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the buffer
and send the data to the Ethernet port when a specific character, entered in hex format, is received. A second
delimiter character may be enabled and specified in the Delimiter 2 field, so that both characters act as the
delimiter to indicate when data should be sent.
ATTENTION
In order to enable a delimite
r, packet length must be set to 0. Delimiter 2 should only be enabled in
conjunction with Delimiter 1 and never on its own; otherwise there may be data errors. Even when a delimiter
is enabled, the
OnCell G3100 will still pack and send the data when the amount of data exceeds 1 KB.
Delimiter process (default=Do Nothing): The Delimiter process field determines how the data is handled
when a delimiter is received. Delimiter 1 must be enabled for this field to have effect. If Delimiters 1 and 2 are
both enabled, both characters must be received for the delimiter process to take place.
• Do Nothing: Data in the buffer will be transmitted when the delimiter is received.
• Delimiter + 1: Data in the buffer will be transmitted after 1 additional byte is received following the
delimiter.
• Delimiter + 2: Data in the buffer will be transmitted after 2 additional bytes are received following the
delimiter.
• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.
Force transmit (default=0 ms): This parameter defines how large a gap in serial communication the OnCell
G3100 will allow before packing the serial data in its internal buffer for network transmission.
