An explanation of these bytes/bits is as follows:
b6 (Byte 0) - Signifies the low range (0) or high range (1) applicable to the PPS-1326.
b6 (Byte 1) - Signifies whether or not the PPS-2322 are in tracking mode.
b5 - Signifies which mode the power supply is operating in, constant current or constant voltage.
b4 - Signifies whether or not the overvoltage has tripped.
b3 - Signifies whether or not the overcurrent has tripped.
b2 (Byte 0) - Signifies whether or not the overcurrent protection is on or off.
b2 (Byte 1) - Specifies whether or not the "OCP" condition is occurring on channel 1 (0) or channel 2 (1).
b1 - Signifies whether the outputs (CH1 or CH2) are on or off.
b0 - Defines whether a command error has occurred.
Example: Reading the PPS-2322 Status
After the "STATUS?" command is entered, the following six ASCII codes will be read from the PPS:
32 32 32 36 0D 0A 'ASCII Code'
- convert to hex form
2 2 2 6 'Hex Code'
- byte 0- -byte 1-
- convert to binary form
0010 0010 0010 0110
EXPLANATION OF STATUS BITS: Constant Voltage channel 1, Overcurrent protection off, Output 1 ON,
Constant Voltage channel 2, Over current has been tripped channel 2, Output 2 ON.
5.5 PROGRAMMING THE POWER SUPPLY
This section provides more detailed requirements of the programming commands available. Upon powering up, the
PPS Series undergo self test and default to the factory settings.
