Cable requirements
| Classification | Typical cable | Cable requirements |
| High-speed signal cable | Ethernet | Above CAT-5 shielded cable |
| Low-speed signal cable | Serial port signal and low-speed IO | Standard cable |
| Power cable | DC power cable DC24V | Selected according to power |
| Display cable | HDMI display cable | Shielded cable |
Other precautions:
- For the relationship between the cross-sectional area of the conductor and the current-carrying current, please select the power cable correctly according to the equipment power.
- When the length of parallel cable runs is increased, the spacing shall be increased appropriately.
- When near power cables or in harsh electromagnetic environments, the magnetic ring can be used to reduce the interference.
- When the length of parallel cable runs increases, the spacing should be increased appropriately to reduce cross interference.
- In addition to keeping spacing, shielding plates can be added between different types of cables to achieve shielding.
