RS232C Connector, pin-out assignment and wiring
Fig.4-47 shows the connection between the HUST H6D Serial Controller and the
computer (PC). When carrying out the wiring, take the following precautions:
1. The RS232C cable shall not exceed a length of 15m.
2. In case of existence of massive noise generators (e.g., EDM processor, welding
machine, etc.) in the vicinity, Twist-pair type cables shall be used, or such an
environment shall be avoided. The controller and the PC shall NOT share a
common power socket with an EDM or welding machine.
3. Make sure the voltage of the interface at the PC end is within the range of
10~15V.
