3 Features and Functions
A fly-wheel diode is provided at the drain of the MOSFET. It is used in closed loop
current release and to protect the MOSFET from any high reversed voltage, which
may be generated by the inductive load when the output stage is being switched
from ON to OFF.
The following SCPI examples show the way to read a digital input channel and to
output a digital output signal.
SCPI Example 1, Read one bit of a digital input channel
-> DIG:DATA:BIT? 1,(@101)
<- 1
SCPI Example 2, Read a digital input channel
-> DIG:DATA:BYTE? (@101)
-> 9
SCPI Example 3, Output a signal at one bit of a digital output channel
-> SOUR:DIG:DATA:BIT 1,6,(@201) // Set to "1" for bit 6 of channel 201.
-> SOUR:DIG:DATA:BIT? 6,(@201)
<- 1
SCPI Example 4, Output a signal at a digital output channel
-> SOUR:DIG:DATA:BYTE 123,
-> SOUR:DIG:DATA:BYTE?
<- 123,123,123,123

(@201:204)
// Read bit 1 of channel 101
// The return value will be either 1 or 0.
1 means there is a input at that
particular bit.
// Read digital input at channel 101
// The return value is in decimal, where
9 means bit 0 and bit 3 of channel 101
have digital inputs.
// Query the output signal at bit 6 of
channel 201.
// Return of "1" means there is an
output signal.
// Output 123 (in decimal) at channel
201 to 204.
// Query the output signal at channel
201 to 204.
