Proper usage
● In case of connecting PC with SCM-WF48, SCM-US48I or SCM-US, when changing PC USB port and connecting this
unit to another (changed) USB port, USB driver will be reinstalled. This is not a malfunction.
● When connecting SCM-US or SCM-US48I communication module, please connect PC first. Then, connect RS485
communication product afterward. When disconnecting the units, remove the unit in reverse order.
● Using the Twisted pair cable (AWG24), which is suitable to RS485 communication is recommended. If the Twisted pair
cable is not used, be sure preserving identically the length of A(+) and B(-) cables.
● After connecting SCM-WF48 with RS485 communication DEVICE, be sure to attach the terminating resistor (120Ω).
After connecting SCM-38I, SCM-US48I with RS485 communication DEVICE, be sure to attach the terminating resistor
(100 to 120Ω).
● In case of connect PC with SCM-WF48, SCM-US48I, or SCM-US , No. of COM Port will be numbered in order.
This is not a malfunction. (e.g. COM 14, COM 15, ..., COM 256)
● When connecting SCM-WF48, SCM-US48I or SCM-US with USB cable, check COM port number before communication.
It may take some time for computer to detect the cable after the cable is connected. (This is not a malfunction.)
● When connecting PC with SCM-WF48, SCM-48I or SCM-US, do not use the extension cable to extend USB cable length.
It may cause a malfunctions.
● Be cautious when using SCM-WF48 or SCM-US as non-isolated type.
Check the connection, disconnection and short of communication cable before supplying the power to SCM-WF48.
● Only use Autonics products that are available for SCM-US.
● Observe the rated voltage.
● To avoid malfunctions due to noise, do not place the unit close to a high-voltage power line.
● Proper application environment
(Avoid following environments for unit to be used.)
• Where severe vibration or shock exists
• Where close to a strong alkali or strong acid
• Where direct rays of light exist
• Where near facilities generating strong magnetic forces or electric noise.
● Storage
Keep the unit -20 to 60℃, 35 to 85%RH with avoiding direct rays of light. It is recommended to keep the unit package
as it is.
● Installation environment
• It shall be used indoor
• Altitude max. 2000m
• Pollution degree 2
• Installation category II
