11-1 Preparation for Data Communications with a PT and Data
Communication Procedure
11-1-1 Connection to PT
To send/receive data between a PT and the NT-series Support Tool (personal
computer), connect them with a cable.
Cable
The recommended communication cable supplied by OMRON has a 25-pin
RS-232C connector at the end for connection to a personal computer. To con-
nect to a PC/AT compatible personal computer that has a 9-pin (female) con-
nector, use a 25-pin to 9-pin conversion adapter available on the market.
Recommended cable is in the Appendix J.
Connection
Connect the RS-232C connector at the personal computer to the Support Tool
connection port at the PT.
For the location of the connection port in the PT, refer to the Appendix of the
User’s Manual of the PT. With some models of PT, it is necessary to disconnect
from the host before connecting the Support Tool.
An example of connection is shown below assuming NT31/NT31C.
RS-232C, 9 pins
11-1-2 Available Data Communication Methods by PT Models
Data communication is possible by the two methods indicated below.
Batch transmission of all screen data
Data transmission in screen and data units (individual transmission)
Whether or not individual data transmission is possible depends on the PT model
as shown below.
