The external wiring method at the handle expansion port is shown in Fig. 5. 5
Fig. 5. 5 The connection diagram at the handle extension interface
The extension interfaces of indefinitely variable speeds handles and the all-touch handles
provide CAN communication, RS232, 2 routes for outputs and 2 routes for input signals. RS232
interface is mainly used for equipment debugging and system software upgrade. Taking the
indefinitely variable speeds handle as an example, the pin diagram at handle extension interface is
shown Figure 5. 6, and the color correspondence of 12-core handle extension cable to that in
handle extension interface is shown in Figure 5. 7.
