1. Purchase suggestions
Interface matching: confirm whether the device requires DB9 male or female (this line is DB9 Male to DB9 Female).
Power supply requirements: check the USB interface voltage (5V or 12V) to avoid device incompatibility.
Cable length: 1~3 meters is recommended for industrial applications. Too long may cause signal attenuation.
Shielding performance: double-layer shielded cable is preferred to reduce electromagnetic interference.
2. Safety precautions
Avoid overload: The maximum current of USB power supply is usually 2A, and overload may damage the device.
Anti-short circuit: Make sure the DB9 interface is correctly connected to avoid short circuit of pins.
Waterproof and dustproof: It is recommended to use protective sleeves in industrial environments.
Regular inspection: Long-term bending may cause the wire to break, and regular maintenance is required.
3. FAQ (Frequently Asked Questions)
Q1: Can this cable be used for USB 3.0 devices?
A: No, it only provides 5V/12V power supply and does not include USB 3.0 data transmission function.
Q2: Does the DB9 interface support RS-485?
A: No, it is only applicable to RS-232 standard devices. If RS-485 is required, an additional converter is required.
Q3: Can only the DB9 part be used without USB power supply?
A: Yes, USB power supply is an optional function and does not affect DB9 communication.
Q4: How many meters can the cable support?
A: The RS-232 standard recommends not more than 15 meters. Too long may cause signal loss.
