Example of Connections

•In case of connecting PC with SCM-WF48, SCM-US48I or SCM-US, when changing PC USB port and connecting thisunit 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 RS485communication 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 paircable 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 packageas it is.
•Installation environment
•It shall be used indoor
•Altitude max. 2000m
•Pollution degree 2
•Installation category I
