1. Before Using
In factories or poor sites, noise or surges generated from outside and incoming along the communication lines
frequently cause communication errors, and this continuous electrical shock poses the risk of damaging expensive
equipment and facilities.
BASO-1010D2/ISO on the System Base is a product that provides high performance and reliability to maintain and
utilize facilities and equipment by reducing failures or breakdowns through the built in protection against noise and
surge incoming along the RS232 line.

• Supports RS232 primary(DB9 Female) DCE mode and secondary(DB9 Male) DTE mode
• Built-in ±15kV, ±30kV ESD Protection
• Built-in primary 350W, secondary 300W Surge Protection
• ±3kVrms Digital Isolation
• Supports TXD, RXD, RTS, CTS signals
• No External Power Required via the primary side RS232 signal line
• Power Supply available through the primary side DB9 pin(5~12VDC)
What is Serial?
RS-232 is most simple and common equipment communication standard, established by the Electronic Industries
Association(EIA). It supports only 1:1 communication and normally used in a communication distance within 100m.
Due to its simplicity and economical feature, it has been used in many industrial sites so far.
RS-422 and RS-485 is the interface complements the shortcoming of RS-232. RS-422 and RS-485 with four or two
signal lines support long communication distance up to 1.2km as they have a stronger response to noise. They also
support multi-drop method, which enables communication in a more complex and extensive environment.
What is isolation?
Isolation is a function which converts electrical signals into other forms such as optical and converts them back into
electrical signals for communication. This electrical insulation of the input/output signals protects the equipment from
strong electrical shocks coming through the line generated by surges, external motors, actuators and so on. When
communicating with such expensive equipment, isolation function is necessary to protect the equipment at a low cost.
Digital isolation provides faster and greater reliability than traditional opto-isolation which is optical, with small size,
high isolation performance and low power consumption.
