module accumulates data in its buffer as it waits to receive a delimiter. If there is a break in
communication, data will be held in the buffer as the module continues to wait for a delimiter. The
Force transmit field allows you to specify the maximum amount of time that the module will wait
for data. With Force transmit enabled, the module will automatically pack the data in the buffer for
network transmission if no data is received for the specified time.
When set to 0, Force transmit is disabled, which means there is no time limit for how long the
module will wait to receive data. When set between 1 and 65535, the module will pack data as
soon as there has been no serial communication for the specified time.
The optimal force transmit time depends on your application, but it should be larger than one
character interval within the specified baud rate to have any effect. 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 one character is 10 bits, and the time required to transfer one character is
(10 bits / 1200 bits/s) × 1000 ms/s = 8.3 ms.
Since it requires about 9 ms to send one character, the Force transmit should be 10 ms or more to
have any effect. At 9 ms or less, the module will simply pack every character as it is received,
which would be the same as if no delimiter characters or Force transmit time were specified at all.
Destination IP address 1/2/3/4
Setting Factory Default Necessity
IP address or domain name
(e.g., 192.168.1.1)
None Required
Use this field to specify the remote hosts that the module will connect to.
ATTENTION
Up to 4 connections can be established between the module and hosts. The connection speed or
throughput may be low if one of the four connections is slow. In this case, the other 3 connections
will be delayed while waiting for the slowest connection to finish transmitting or receiving.
ATTENTION
The Destination IP address parameter can accept domain names address in place of IP addresses
if a DNS server has been configured. For some applications, you may need to send the data
actively to a remote destination’s domain name address.
TCP connect on
Setting Factory Default Necessity
Start up,
Any Character
Start up Optional
Start up: The module will attempt to establish a TCP connection as soon as it is powered on.
Any Character: The module will attempt to establish a TCP connection as soon as the module
starts receiving serial data.
