Wiring diagram for NTXS :
Pin description of the power connector for NTXS models is as follows:
2.3
NTXS models have two communication Ports.
One port of NT2S models has RS232/CMOS signals. This port is used to connect to PLC. The other port
has RS232 signals and this port is used for receiving configuration setup and printing.
NT3S has Multi-Signal ports meaning RS232/RS485/CMOS signal level ports. NT3S units can
simultaneously communicate with two devices on these serial ports. Units can receive data from PC on
either of the ports. Both the ports are also capable of Serial Printing. Each port has to be configured for
their function. Even if both the ports are connected to PLC, user can download data from NT-XS software
on either of the ports. For Programming cable details, please refer to Appendix.
Different cables are required for different devices. Cable details for any particular device are given in the
Operation Manual of that device. Pin description of the communication Ports for NT2S and NT3S models is
as given in following pages.
should be made to a central star point as poor site earths can introduce noise into a system.
Do not power unit and inductive loads with the same power supply even though there is enough
immunity in the NTXS to withstand the transients present on these lines. Avoid using power
supplies with large capacitive outputs which may cause problems if power is cycled within a short
time period.
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 equipment damage. DC voltage sources should provide proper
isolation from main AC power and similar hazards.
