Two versions of Personality modules are available for the LC module:
• Group 1 module (Westinghouse part number 1C31169G01)
— Provides an RS-232 electrical interface
— Appropriate for installations where the distance between the LC card and
the other Modbus speaking device is 50 feet (15 meters) or less.
• Group 2 module (Westinghouse part number 1C31169G02)
— Provides an RS-422/RS-485 electrical interface
— Appropriate for distances up to 4000 feet (1220 meters).
The field connection to the LC module can be made either at the nine pin J2
connector of the personality module or at the terminal block of the base unit. It is
common for RS-422 and RS-485 communication, because the cable length is
typically longer, for the connection to be made as field wiring rather than as a premanufactured cable. The terminal block connection is convenient for theses cases.

LC模块有两种版本的个性模块：
•1组模块（西屋零件号1C31169G01）

LC模块的现场连接可以在9针J2处进行
个性模块的连接器或基本单元的接线盒。它是
常见于RS-422和RS-485通信，因为电缆长度
通常较长，用于连接现场布线，而不是预制电缆。这种情况下，接线板连接很方便。
