RS232: 4.5V or -2.0V according to the type of the instrument.
SPI、IIC、PO: 9.4V
Digital voltage:
RS232: Off
SPI、IIC、PO: 4.2V
When the set voltage exceeds the upper limit, the system will automatically
adjust it to the corresponding upper limit.
8. Voltage lower limit **V
Analog voltage:
RS232: 2.0V or -4.5V according to the instrument type.
SPI、IIC、PO: 1.4V
Digital voltage:
RS232: Off
SPI、IIC、PO: 1.4V.
When the set voltage exceeds the lower limit, the system will automatically
adjust it to the corresponding lower limit.
9. Data Number per frame Upper limit 3 Byte
In SPI protocol setting, the upper limit of transmission data per frame is 3 Byte,
if the specified value is higher than 3 Byte, the system will automatically adjust
it to be 3 Byte.
10. Data Number per frame Lower limit 1 Byte
In SPI protocol setting, the lower limit of transmission data per frame is 1 Byte,
if the specified value is lower than 1 Byte, the system will automatically adjust
it to be 1 Byte.
11. IIC Address upper limit 127
In IIC protocol setting, when the user-defined address exceeds 127; this
message will appear.
12. IIC Address lower limit 0
In IIC protocol setting, when the user-defined address is lower than 0; this
message will appear.
