When using the memory linkmethod, however, use a connector that matches with the RS-422A port at theCPU Unit (PC). Some Units come supplied with one connector and connectorhood.Check the required parts and prepare them in advance.NameMakerRemarksOMRON9-pin connectorConnector and Connector hoodConnectorsetXM2S-0911S003ConnectorXM2A-09019-pin connectorMade by OMRONConnectorhoodXM2S-09119-pin connectorMade by OMRONCableTKVVBS4P-03Tachii ElectricWire Co., Ltd.1.25-N3A(fork type)Japan SolderlessTerminal MFGY1.25-3.5L(fork type)Molex Inc.CrimpterminalsNoteModelRecommended cable size:AWG22 tot 18(0.3 to 0.75 mm2)1.

Before connecting or disconnecting cables between devices, make surethat the power supply to all of the connected devices (NT21, PC, etc.) isOFF.Examples of applicable terminalsRound typeFork type6.2 mm or less5-26.2 mm or lessConnecting to the Host’s RS-232C PortThis section explains how to connect to the host’s RS-232C port through anRS-422A/485 cable. This explanation focuses on connections to OMRON PCs,although any RS-232C device can be connected using the memory link method.The following diagram shows a 1:N connection between the RS-232C ports onseveral PTs and the RS-232C port on the host through Link Adapters andRS-422A or RS-485 cable.

Use the 1:N connection NT Link method (standard or high-speed)instead of making the 1:1 connection. For details, refer to Using the 1:N NT Linkmethod (page 55) or Using the High-speed 1:N NT Link method (page 60).5-2-1 Host Types and SettingsThe usage conditions are the same as they are when both the PT and host areconnected through their RS-232C ports.Refer to the pages listed below for details on the various connection methods,the hosts that can be connected with each method, and the required host settings.MethodReferenceHost LinkUsing the Host Link Method (page 40)1:1 NT linkUsing the 1:1 NT Link method (page 51)1:N NT linkUsing the 1:N NT Link Method (page 55)High-speed 1:N NT linkUsing the High-speed 1:N NT Link Method (page 60)Memory linkMemory Link Method (page 63)5-2-2 1:N Connection Using the Host’s RS-232C PortThis section explains how to connect several NT21 PTs through their RS-232Cports to a single host through its RS-232C port using Link Adapters andRS-422A/485 cable.
Link Adapters (NT-AL001 or NS-AL002) are required toconvert communication methods between the RS-232C and RS-422A/485 formats.The following diagram shows a 1:N connection between the RS-232C ports onseveral PTs and the RS-232C port on the host through Link Adapters andRS-422A or RS-485 cable. NT-AL001, NS-AL002 Link Adapters are required toconvert communication methods between RS-232C and RS-422A/485.Connecting the NT21s to the Link Adapters (RS-232C)NT21NT-AL001 orNS-AL002NT-AL001HostRS-232C cable(2 m max.)95SectionConnecting to the Host’s RS-232C Port5-2Compatible Cables with Attached Connectors:XW2Z-070T-1 (9-pin to 9-pin, 0.7 m)XW2Z-200T-1 (9-pin to 9-pin, 2 m)NT2161Link AdapterAbbreviation Pin numberRS-232Cconnector9561Pin number AbbreviationFGConnectorhoodConnectorhood–11–SD22SDRD33RDRS44RSFGRS-232CterminalblockCS55CS+5V66+5V–77––88–SG99SGShield(9-pinconnector)(9-pinconnector)95When an NT-AL001 Link Adapter is being used, the RS-232C cable can be connected to either serial port A or B on the NT21.When an NS-AL002 Link Adapter is being used, the Link Adapter connects directly to serial port B on the NT21, so an RS-232C cable is not required.Connecting the NT21-side Link Adapters to the Host-side Link Adapter (RS-422A)Link Adapters(NT-AL001 orNS-AL002)NT21RS-422A(Total length NT-AL001500 m max.)NT-AL001 or NS-AL002 LinkAdapter (NT21)Pin numberPin numberF.
