Proper Usage (SCM Series common)

1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.

2. 12-24VDC or 24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply

device.

3. Use only designated connector and do not apply excessive power when connecting or disconnecting the connectors.

4. Keep away from high voltage lines or power lines to prevent inductive noise. In case installing power line and input signal

line closely, use line lter or varistor at power line and shielded wire at input signal line. Do not use near the equipment
which generates strong magnetic force or high frequency noise.

5. Do not connect or disconnect the USB cable, earphone jack, or RS485 cable quickly and repeatedly while

communicating. It may cause damage or malfunction of the product and PC.

6. After supplying power, connect with the communication output product. When disconnect, communication output product

rst and power last.

7. When connecting multiple SCM-US48I, SCM-US or SCM-WF48 units to a PC, number of COM port goes up in

sequential order and it takes some time to identify and assign number of COM port.

8. When connecting the RS485 communication output product, connect the terminating resistance (SCM-38I, SCM-US48I,

SCM-US: 100 to 120Ω, SCM-WF48: 120Ω) at each end of the communication cable.

9. Use twist pair wire for RS485 communication. If not, use A(+) and B(-) cables in the same length.

10. Use USB cable of designated standard, and do not use extension cable.

11. This unit may be used in the following environments.
