to TCP Client mode IP and port equal to SE5404D
A COM2’s settings (Default Destination IP=10.10.50.100,
Default Destination Port = 4661).
Max Connections (default=1):
This option 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 or greater, up to the specified number of hosts
may open this port at the same time.
Attention
When
Max. Connections
is greater than 1, the Serial server will apply multi connection
application (i.e., 4 hosts are allowed access to the port at the same time). When using a
multi connection application, 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
Request and response Mode
This option determines how the port will proceed if multiple hosts are connected and one or more of the hosts stop
responding when the port is transmitting data. If you select
Reply to requester only
, the port will keep other hosts’
request data in the buffer and continue data transmission to the request host only. If you select
Reply to all
, the
port will transmit reply data to all connected hosts
.
Transparent Mode
The port will allow the other hosts and continue data transmission to al
l hosts. This mode does not take “Response
Interv
al Timeout” into consideration.
IP filtering function is a simple ACL (Access Control List) disabled by setting FILTER_IP to “0.0.0.0”.
One may configure one or group IP for source IP. If IP filter is enabled, only source IP assigned is connected to
Serial Server.
If you check “
Apply to all serial ports
”, it will configure all of the serial ports.
