WORKING MODE AND CONVERSION AGREEMENT
Different serial server working modes and conversion protocols can be selected in different
application occasions, so that it can be used more stably and reliably, which will be described in
detail below.
The use of serial port server is basically divided into two types: with virtual serial port and
non-virtual serial port, as shown in Figure 9 TCP communication diagram and Figure 12 the
function of virtual serial port. The user software with virtual serial port that needs to be docked
is a serial interface ( COM port) , that is, the user software and user equipment are serial ports;
the user software of the non-virtual serial port mode communicates directly with TCP/ IP, but the
user equipment is still a serial port.
In the non-virtual serial port mode, the "conversion protocol part" is divided into three
modes: transparent transmission, Modbus TCP to RTU and Realcom protocol. If the user
software is a fixed protocol Modbus TCP protocol and the lower computer is Modbus RTU, you
