2.4
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.
Pin description of the power connector for NTXS Models is as follows:
2.5
NTXS unit has 2 types of 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 which is used for receiving configuration setup and printing.
Note: NT2S-SF123B-EV2 and NT2S-SF127B-E units have only a PLC port with CMOS signals.
NT3S has multi-signal ports meaning RS232/RS485/CMOS signal level ports.
Note: NT3S-ST126B-E unit has only RS232 and 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 configured for PLC connection, user can
download data from NTXS 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.
