2.7 Wiring Diagram
If wiring is to be exposed to lightening or surges, use appropriate surge suppression devices. Keep AC, high energy and rapidly switching DC wiring separate from signal wires.
Connecting high voltages or AC power mains to the DC input will make unit unusable and may create an electrical shock hazard to personnel. Such a failure or shock could result in serious personal injury, loss of life and/or equip- ment damage. DC voltage sources should provide proper isolation from main AC power and similar hazards.
Pin description of the power connector for base models is as follows:

2.8 Communication Ports
V200 communication ports support three types of serial communication.
They have two communication Ports in which COM1 is
A V200 can simultaneously communicate on both serial ports. The V200 can be programmed from a PC on either port. Both ports can also be used with a serial printer.
Different cables are required to connect the V200 to a specific PLC. Cable details for any particular device are given in the Operation Manual. The pin description of the communication ports for V200 model is as given below:
1. COM1 Port Details:
Pin 8: Reserved 
Pin 7: RX-
Pin 6: TX-
Pin 5: RX+
Pin 4: TX+
Pin 3: GND
Pin 2: 232RXD
