Server & Client Mode
This is when the HelloDevice operates as TCP server AND client. If you are to transmit data from a
serial device to a remote server through the HelloDevice, it will operate as a TCP client. If TCP
connection is requested by a remote client, it will operate as TCP server.
Note:
TCP mode can not be changed during RS232 data transmission.
[HD Port]
[HD Port] is the port number of the HelloDevice for TCP connection in TCP Server mode. The range is
2000 ~ 65535.
[Server IP, Server PORT]
When your HelloDevice is set to TCP Client mode, you need to specify the IP address and the port
number of a remote server that is to communicate with the HelloDevice. The range [PORT] is 2000 ~
65535.
(3) [Notifier]
Data server means the server that administers information of the HelloDevice. This is only when [IP
mode] of the HelloDevice is set to Dynamic IP mode AND the environment requires TCP server
function (DHCP, TCP server). since the IP address keeps changing every 24-hour in Dynamic IP
mode, there is a need for a data center to administer the IP address and other information of the
HelloDevice. To configure a data center, the UDP server socket program which administers setup
information that is periodically transmitted from the PC and the HelloDevice, must be running. (Refer
to Section 5.3)
The HelloDevice sends its IP address and other information to the data server according at an interval
set in [Time Interval]. The range of [Time Interval] is from 90 seconds to 6 hours.
4.4.3 RS232 Communication Parameter
This section describes how to set parameters of the HelloDevice for RS232 communication.
