Thank you for choosing our Autonics product.

Please read the following safety considerations before use.

Safety Considerations

Please observe all safety considerations for safe and proper product operation to avoid hazards.

※ ※

symbol represents caution due to special circumstances in which hazards may occur.

Warning Failure to follow these instructions may result in serious injury or death.

Caution

Failure to follow these instructions may result in personal injury or product damage.

Warning

1. Fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention devices, etc.)

Failure to follow this instruction may result in re, personal injury, or economic loss.

2. Do not disassemble or modify the unit.

Failure to follow this instruction may result in re.

3. Do not connect, repair, or inspect the unit while connected to a power source.

Failure to follow this instruction may result in re.

4. Check 'Connections' before wiring.

Failure to follow this instruction may result in malfunction and damage on the product or PC.

Caution

1. Use the unit within the rated specications.

Failure to follow this instruction may result in re or product damage.

2. Use dry cloth to clean the unit, and do not use water or organic solvent.

Failure to follow this instruction may result in re.

3. Do not use the unit in the place where ammable/explosive/corrosive gas, humidity, direct

sunlight, radiant heat, vibration, impact, or salinity may be present.

Failure to follow this instruction may result in re or explosion.

4. Keep metal chip, dust, and wire residue from owing into the unit.

Failure to follow this instruction may result in re or product damage.

5. Do not disconnect connector or power, when the product is operating.

Failure to follow this instruction may result in re or malfunction.

Proper Usage

●TX Enable signal(RTS signal)

In case of SCM-38I and SCM-US48I, Tx_ Enable signal (RTS signal) is automatically generated according to protocol (Do not need to generate signal on your own)

●Auto-loop Back

SCM-38I has Auto-look Back function. When using Auto-loop back function, please use as 'RS232C' cable connections.

●Termination Resistor

RS485 Communication has many advantages such as fast transmission rate, long distance communication and etc. But if the impedance of transmission line does not match to RS485 network

terminations, the reected wave will be generated. In case of increasing the length of transmission line or using 1 N multi-drops, the reected wave may

cause transmission error.

Therefore in this case, please use termination resistor(100 to 120Ω) at both terminations.

Caution during Use

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

2. 12-24VDC 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.

t 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-US or SCM-US48I 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 (100

to 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.
