SOURce2 subsystem
The SOURce 2 subsystem command is used to set the logic level of the digital output
lines, as summarized in
[:LEVel] <NRf> | <NDN>
:SOURce2:TTL[:LEVel] <NRf> | <NDN>
Set digital output pattern
Parameters
<NRf> =
0 to 15
Decimal format
<NDN>
#Bx
Binary format: x = 0000 to 1111
#Hx
Hexadecimal format: x = 0 to F
#Qx
Octal format: x = 0 to 17
Query
:TTL?
Query digital output value
Description
This command is used to set the logic levels of the output lines of the
Digital I/O port. When set high, the specified output line will be at
approxi5V. When set low, the output line will be at 0V. The four
output lines are internally pulled up to V
CC
and are capable of sinking
500mA and sourcing 2mA. These lines are also capable of switching
external voltages as high as 33V.
Use the following table to determine the parameter value for the desired
decimal digital output pattern:
