When operating with TCP Multiplex mode, the SerialGate sends a
data to the device and waits given amount of time. When there are
no reply within the given time, it will send the next data to the device.
If the value is set to zero, it will not wait for the reply but send the
next available data right away when received.
Low
Latency
Enable
Send the data received from the Ethernet to the serial port as soon
as possible. When enabled, it takes less time to send the serial data,
but will increase the load of the system. When disabled, the load of
the system decreases, but will take more time to send the serial data.
If it is required to send the data to the serial device with less delay,
enable this feature. When sending large amount of data, disable this
feature.
Allow New
Connection
Disable
When using TCP server, COM Redirector, or Telnet (RFC-2217)
mode, this feature allows new connection when enabled. While
communicating, if new connection request arrives, the SerialGate will
disconnect the current connection and permit the new connection.
TCP
Nodelay
Disable
When communicating with TCP, this feature will allow whether to
send the data at once using the Ethernet port.
If it is disabled, data received from TCP will be sent after they are
gathered. It is recommended when using high speed data
transmission or packet transmission.
If it is enabled, data received from TCP will be sent immediately,
allowing less delay in Ethernet and serial communication. However, it
is not optimized for high speed communication or packet
transmission.
Port Login
Disable
User/Password can be set in TCP Server, TCP Broadcast, TCP
Multiplex mode.
When ‘Port Login’ is enabled, ‘User/Password’ can be modified.
User
none
User/Password can be set in TCP Server, TCP Broadcast, TCP
Multiplex mode.
When ‘Port Login’ is enabled, ‘User’ can be modified.
Password
none
User/Password can be set in TCP Server, TCP Broadcast, TCP
Multiplex mode.
When ‘Port Login’ is enabled, ‘Password’ can be modified.
