Performance
The CE marking does not apply when the K3SC is used for USB.

  • With RS-232C communications, free-run mode is supported for SD and RD but not for any other signal lines.
  • The enclosure ratings do not apply when USB is used, as the terminal cover needs to be removed.

General Precautions

  • Do not mount the product in the following places:

(1) Locations subject to shock or vibration
(2) Outdoor locations or locations subject to direct sunlight, wind, or rain
(3) Locations subject to temperatures or humidity outside the specified ranges
(4) Locations subject to condensation or icing
(5) Locations subject to large amounts of dust
(6) Locations subject to flammable gases or objects
(7) Locations subject to corrosive gases (in particular sulfide or ammonia gases)

  • Be sure to check power supply specifications, terminal numbers, and polarities before performing wiring.
  • Turn OFF the power supply before performing installation or wiring.
  • Turn OFF the power supply before removing the terminal cover. Accidentally touching the terminals may result in electric shock.
  • Do not connect anything to unused terminals.
  • Do not touch the slits and terminals while power is being supplied.

Correct Use

  • Perform wiring with crimp terminals that are suitable for M3.5 screws.
  • Install the product as far away as possible from devices that generate strong high-frequency noise (e.g., high-frequency machines/welders) or surges.
  • Do not pull on the USB cable. Doing so may cause the cable to come loose.
  • Almost all application programs run with the K3SC-10 driver, which provides a virtual communications port for USB communications. Some application programs do not run, because this driver does not support all of the API functions.
  • The K3SC-10 is not simply a voltage level converter. Communications data is converted by a built-in CPU. Depending on communications conditions, processing may not be able to keep up with communications, and occasionally data corruption or data omissions may occur. If necessary, reduce the baud rate or the frequency of communications, or take other suitable countermeasures.
