Definitions
JP1:
REF Selects INT or EXT reference for the ADC. The
default setting is INT.
JP2:
Selects the common mode voltage for the ADC.
Choices are EXT, 2.5V, 2.048V or GND. The default set-
ting is 2.048V.
JP3:
VCCIO sets the output levels at J2 to either 3.3V or
2.5V. Use 2.5V to interface to the DC890 which is the
default setting. Use 3.3V to interface to the DC590.
JP4:
JTAG is used to program the CPLD. This is for fac-
tory use only.
JP5:
EEPROM is for factory use only. The default posi-
tion is WP.
JP6:
+IN1 COUPLING selects AC or DC coupling of +IN1.
The default setting is DC.
JP7:
IN3 COUPLING selects AC or DC coupling of IN3.
The default setting is DC.
JP8:
–IN1 COUPLING Selects AC or DC coupling of –IN1.
The default setting is DC.
JP9:
COM sets the DC bias voltage for the COM pin to
either CM or GND. CM is the default setting.
