Page 6: Communicating With External Devices
1.1 Communicating with External Devices 1.1.1 Communication Between GT and External Devices The communication between the GT and an external device is carried out via the GT internal memories. The external device can “control screens” or “display data” by reading/writing the GT internal memories. Reference: For the details on the commands to read/write the internal memories, refer to <Chapter 3, 4 and 5>. -
Page 7: Communication Mode Type
1.1.2 Communication Mode Type The general-purpose serial communication for the GT supports three types of communication modes. Select one of them as usage. (1) Command Response mode The command response mode is an interactive communication mode that an external device sends a command to the GT, and the GT sends back a response. - Page 8 (3) Two-Way 2 mode In the two-way 2 mode, an external device sends a command to the GT, and the GT sends a message for transmitting the information on the switch input/data settings. In this mode, the GT sends back a response for a command to the external device.

RS232C type.) Key Point: GT01 does not have the terminal for CS/RS signal control. When replacing GT01 with GT02, GT02L, GT05, GT12, GT32 or GT32-E, setting the CS/RS control to "Off" enables to replace the models without changing the wirings for external devices. -
Page 16: Connecting To External Devices
2.2 Connecting to External Devices The GT is connected to an external device with a RS232C or RS422(RS485) interface. The RS485 communication can be used in the command response mode only. 1:1 connection 1:1 connection is to connect one external device with one GT. The connection is cross connection that each other’s sent data signals and received data signals are exchanged. -
