The MCH200TSV0 adapter is used to connect a µC2controller to the
supervisor network, if the RS485 serial port is occupied by the
connection to the remote terminal MCH2000T*00.
Assembly
• disconnect the telephone cable from the RJ12 connector at the rear of
the terminal MCH2000T*00;
• open the cover on the 15-way pin strip using a pair of wire cutters
(Fig. 3);
• insert the pin-strip to 4-pin plug adapter in the direction shown in the
figure (pin 1 on the terminal is marked by a triangle).
• connect the converter to the RS485 network and set the parameter H10
(serial address) of the µC2to the desired value;
• insert the telephone cable.
The RS485 serial line should be terminated by connecting a 120
Ω
1/4 W
resistor between the + and - terminals (see Fig. 2).
WARNINGS:
• Carefully fasten the adapter so as to avoid accidental disconnection;
• Connect the wiring with the power supply disconnected;
• Keep the adapter cables separate from the power cables (relay outputs).
