tions with personal computers. The CPM1A using the Host Link can also com- municate with Programmable Terminal using host link commands. An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is used for 1:N communications. One-to-one PC Link A data link can be created with a data area in another CPM1A, CQM1, CPM1, SRM1 or C200HS or C200HX/HG/HE PC. An RS-232C Adapter is used to make the 1:1 connection. NT Link Communications High-speed operations can be achieved by providing a direct access by con- necting the CPM1A to the OMRON Programmable Terminal through the NT Link Interface. An RS-232C Adapter is used for this connection.
