9.1.13 RS232C Connection
A proper connection between PC and HUST controller is shown in Fig 9-5. Please refer
to Connecting Manual for more information. When making connection, please be aware
of the followings:
1. The connecting cable should not exceed 15 meters to minimize the potential noise
interference. The voltage at the PC interface should be in the range of 10~15 volts.
2. Avoid working in an environment where is under the direct noise interference from
the machines such as EDM, electric welder, etc. Do not use the same power outlet as
for EDM and electric welder. Twisting the cable may help in noise reduction.
