WE-2100T Series User’s Manual Web Console: Serial Port Settings
8-5
ATTENTION
When Max connection is 2 or greater, the serial port’s communication settings (i.e., baudrate,
parity, data bits, etc.) will be determined by the module. Any host that opens the COM port
connection must use identical serial communication settings.
Delimiter 1 and 2
Default
Disabled
Options
Disabled, Enabled, 00 to FF
Description
These fields are used to define special delimiter character(s) for data packing.
Enable Delimiter 1 to control data packing with a single character; enable both
Delimiter 1 and 2 to control data packing with two characters received in
sequence.
When these fields are enabled, serial data will accumulate in the serial port’s
buffer until the buffer is full or until the specified delimiter character(s) are
received. For example, the carriage return character could be used as a delimiter
in order to transmit each sentence or paragraph in a separate packet.
Delimiters must be incorporated into the data stream at the software or device
level.
Force Transmit
Default
0 ms
Options
0 to 65535
Description
This field controls data packing by the amount of time that elapses between bits
of data.
0: If serial data is not received, the module will wait indefinitely for additional
data.
1 to 65535: If serial data is not received for the specified amount of time, the
data that is currently in the buffer will be packed for network transmission. The
optimal force transmit time depends on your application, but it must be at least
larger than one character interval within the specified baudrate. For example,
assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no
parity. In this case, the total number of bits needed to send a character is 10 bits,
and the time required to transfer one character is 8.3 ms, so the force transmit
time to be larger than 8.3 ms.
