Connection of communication breaker and the computer are shown as follows:
将产品的通讯模块的电源和通讯线接好，通讯模块的通讯线接到"RS-232 转 RS-485 转换模块"的
RS-485 端（注意极性不可接错） ，再将"RS-232 转 RS-485 转换模块"配套提供的"串口线"将"RS-232
转 RS-485 转换模块"的 RS-232 端和电脑的"RS-232 接口"连接好， 如"RS-232 转 RS-485 转换模块"有
电源请将电源线接好，请见图 5，最后接通电源。
Connect the communication module's power supply and communication wires, with the latter one
connecting to RS-485 terminal of "RS-232 to RS-485 module" (poles can't be wrongly connected), and then
using the serial port line provided accompanying with "RS-232 to RS-485 module" to connect RS-232 terminal
of "RS-232 to RS-485 module" and "RS-232 interface" of the computer. If the "RS-232 to RS-485
module" is provided with a power supply, please connect the power line (see Fig. 5), and plug in the power
supply at last.
4.2 整定电流、整定时间调节
运行上海良信 "MCCB 通讯系统.exe"软件（见图 6） ，设置好配套的参数：COM 端口、波特率、子
站地址（波特率和子站地址参数需要和连接的断路器一致，产品出厂默认设置为：波特率 9600、子站地址
3。 ） 。设置好配套参数后用鼠标点击软件界面的"连接"按键。如产品通讯连接正常（见图 7） ，通讯状态
灯点亮。如连接不正常则请用鼠标点击软件界面的"断开连接"按键后重新设置好配套参数或检查接线是
否正确后再次连接，直到通讯连接正常。
Run "MCCB communication system.exe" software provided by Shanghai Nader Electrical Co., Ltd. (see
Fig.6) and set the parameters: COM port, baud rate, sub-station address (The parameters include baud rate and
sub-station address need to be the same with the connected breaker. Factory default settings: baud rate 9600 and
sub-station address 3). After setting the parameters, click the "Connect" button on software interface, if
communication link is working correctly (see Fig. 7), communication status light will be on; if not, please click
the "Disconnect" button on software interface, reset parameters and connect again after you make sure wiring is
