LIS connection Instruction
1. Communication Mode & Parameter Setting
1.1 RS232 Port Parameter Setting
Baud rate：38400
Data Bits：8
Stop Bit: 1
Check bit：N/A
Data cable should directly connected with 2nd,3rd,5th feet, One end is male
connection, the other end is 9 pin SATA(female connection).
1.2 The protocol is one way communication. The instrument send the data
directly by RS232 port, the computer does not have to response to the received data.
2. Data Transmission form

4, If test item is CRP, the test results will be showing CRP and hsCRP separately.
The test results higher than 5,
CRP: Actual test result
hsCRP: >5.0mg/L
CRP <5.0mg/L
The test result lower than 5,
CRP<5.0 mg/L
hsCRP : Actual test result
Reference value:
CRP: <10mg/L
hsCRP<3mg/L
