Their uses are indicated in the tablebelow.CommunicationPortUsable Communication MethodsSerial port AHost Link1:1 NT Link1:N NT Link*Memory Link(NT Support Tool connection)(Bar code reader input function)RS-232CSerial port BHost Link1:1 NT Link1:N NT Link*Memory LinkRS-232CCommunications* There are two 1:N NT Link communications rates: standard and high-speed.Communication Methods That Can Be Used with the HostThe following communication methods can be used with the hosts that can beconnected to the NT21.• RS-232C• RS-422A• RS-485The communications types that are actually supported vary with the host.
Fordetails, refer to Section 4 Connecting to the Host from the RS-232C Port andSection 5 Connecting to the Host from the RS-422A/485 Port.Converting Communication Type with the RS-232C/RS-422A Link AdapterAn OMRON NT-AL001-E or NS-AL002-E Link Adapter can be used convertfrom RS-232C communications to either RS-422A or RS-485.• RS-232C ⇔ RS-422A• RS-232C ⇔ RS-485There are two models of Link Adapters available with different features:• NT-AL001 Link AdapterThe RS-232C port is insulated from the RS-422A/485 terminals.
An RS-232Ccable (2 m max.) can be connected to either serial port A or B on the NT21.• NS-AL002 Link AdapterThe RS-232C port is not insulated from the RS-422A/485 terminals. The NSAL002 Link Adapter can be connected directly to serial port B on the NT21.(The NS-AL002 cannot be connected directly to serial port A on the NT21.)10SectionMethod for Connection to the Host2-1Combinations of Communication Method and Connection MethodThe connection methods that can be used depending on the communicationmethod used and the communications type for communication between theNT21 and the host are indicated in the table below.Usable CommunicationMethodCommunicationtype at HostUsable Connection MethodDetailsHostLink1:1 NTLink1:NNTLinkMemorylinkffffDirect 1:1 connectionPTHostRS-232C63RS-232C (max.

When the NT-AL001 is being connected to the NT21,a 5-V power supply is output from pin 6 of serial port A or B in the NT21.
Connect pin 6 of the Link Adapter’s RS-232C connector with pin 6 of the NT21’sRS-232C connector.When the NT-AL001 is being connected to a host and power is not suppliedfrom the host’s port, connect an external power supply to pins 6 and 9 of theLink Adapter’s RS-232C connector. Connect the +5-V line to pin 6 and the SGline to pin 9.• Never connect or disconnect cables or Units to an NT-AL001 or NS-AL002while the power is ON. Be sure to turn OFF the power supply of the NT21 orhost before connecting or disconnecting the cables.• A +5-V power supply is output from pin 6 of serial ports A and B in the NT21. It ispossible to use the power from both ports simultaneously, but the maximumcapacity is 150 mA max.
total. Do not exceed 150 mA total output.• When using RS-422A or RS-485 communications, it is convenient to use anNS-AL002 Link Adapter and make a direct connection to serial port B of theNT21. However, there is no insulation between the NS-AL002’s RS-232C portand RS-422A/RS-485 port.12SectionNames and Functions of Parts2-22-2Names and Functions of PartsBefore starting operation, the names and functions of the parts of the NT21 aredescribed here as a confirmation. A method of hardware settings is also described.Front ViewDisplayMonochrome LCD screen with backlightRUN Indicator• Lit in green while theNT21 is in the RUNmode.The whole area of the screen is a touchpanel that works as an input device.• Lit in orange or red whenthe battery is low (orangein the RUN mode, red inother modes).Reference: The NT21 comes in two body colors.NT21Body ColorNT21-ST121-EBeigeNT21-ST121B-EBlack13SectionNames and Functions of Parts2-2Rear ViewExpansion interface connectorWhen using an Expansion Interface Unitsuch as a Memory Unit, connect it here.Battery coverThere is a battery holder beneath this cover.
