Step 1. Understanding what is FMM125 RS232/RS485 TCP
Link mode
In this mode link with external device (for example PC) using text messages can be established.
FMM125 has to be connected to the external device through RS232 or RS485. Any string of data
coming to RS232 or RS485 will be routed to server (if link is currently active). Messages that are
exchanged between FMM device and server, have to be packed in Codec.12 format. Here for TCP
link establishment we will be using Hercules. For sending messages from external device to server
over FMM125 Terminal will be used.
Step 2. Setting parameters in configurator for TCP Ascii
mode test
First of all, in the FMM125 configurator you have to set parameters for RS232 or RS485 (depends
on which RS232 or RS485 port you are using) in global parameters window.
Here in RS232 settings section Baudrate can be chosen to any available. Mode has to be chosen to
TCP Ascii.
2.1. Message Timestamp
Message Timestamp parameter is used to determine if it is necessary to include timestamp in RS232
TCP packet when sending to server. If parameter is Enabled, then Codec 13 is used for data sending.
Otherwise, Codec 12 is used.
You can also use RS485 which is also suitable for Ascii TCP Link mode. In order to make a link
