Considerations
• Make sure that the RS-232 connection cable shield is single-point grounded.
• For the connection method of a peripheral device, check the specifications of the peripheral device.
• Do not short-circuit the FG and SG signals of the RS-232 connection cable. When the FG and SG signals are connected
inside of the peripheral device, do not connect the FG signal to this product.
• For devices connected to this product, using the same power source is recommended.
• When a device to be connected has a 3-pin power plug or when the device or its power plug has a grounding wire, connect
the plug to a grounding receptacle or ground the grounding wire with a ground resistance of 100 ohms or less.
