Connecting to the RS-232C Port at the Host Section 4-1

Using the NT Link (1:N) Method

Compatible Host Units

The OMRON PCs that can be connected using the NT link (1:N) method are the CS1-series CS1G/H and the C-series C200HX/HG/HE(-Z)E, CQM1H, and SRM1 only. With the CS1-series PCs, it is possible to connect a 1:N NT Link us- ing a CS1W-SCU21 Serial Communications Unit.

Check the model and series of the PC as well as the model of Serial Commu- nications Board or Unit being used before making the connections.

The host units that can be connected to the NT31/NT31C by the NT link (1:N) method using the RS-232C ports of both units are indicated in the table below.

*1 A CS1W-SCB21 or CS1W-SCB41 Serial Communication Board or CS1W-SCU21 Serial Communications Unit is required.

*2 One of the following Communication Boards is required: C200HW-COM02/COM04/COM05/COM06 (-EV1)

*3 A CQM1H-SCB41 Serial Communication Board is required.

Reference: The -V1 versions of CS1-series PCs support the high-speed 1:N NT Link as well as the standard 1:N NT Link. Furthermore, the high-speed 1:N NT Link can be used in earlier versions of CS1-series PCs by installing a new version of Serial Communications Board or Unit. For details, refer to Using the High-speed NT Link (1:N) Method (page 75).
