If the pin number is not described, it is because it is not used.
The RS232 specifications are described in chapter E “RS232 Mode”.
In compliance with electromagnetic compatibility standards, use shielded
cables for connecting the interfaces. Connect the screening to the chassis
earth of the other equipment. Without this, “noise” can be generated which
can cause damage to equipment.
Comply with the cut off rating for the set point outputs: 125 V AC - 0.3 A
or 30 V DC - 1 A.
Overvoltages and overcurrents can cause internal electrical damage.
