8.8. Global Output Commands
8.8.1. Description
Global commands are a way to quickly set all power supplies on the RS-232/485 bus to
the same setting. For example, sending “GOUT OFF” is one way to turn a whole group of
supplies OFF at nearly the same time.
CAUTION
After sending a global command, it is important that the controller wait
200 mSec before sending any more RS-232/485 messages.
If the command contains an error, such as incorrect syntax or range
values, NO error response will be returned by any power supply.
Table 8.5: Global Output Commands
1 GRST Reset. Brings the power supply to a safe and known state:
Output voltage: 0V, output current: 0A, OUT: Off, Remote: RMT 1,
AST: Off OVP: Max, UVL: 0.
The conditional register (FLT and STAT) are updated. Other registers are not
changed.
Non-Latching faults (FB, OVP, SO) are cleared, OUT fault stays
2 GPV n Sets the output voltage value in volts. The range of voltage values is shown in Table
8-7. ‘n’ may be up to 12 char plus dec. pt
3 GPC n Program the output current value in amperes. The range of current values is shown
in Table 8-6. ‘n’ may be up to 12 char plus dec. pt
4 GOUT
Turns the output to ON or OFF:
“OUT 1/ON” = turn on
“OUT 0/OFF” = turnoff, clears CV and CC bits in the Status Condition (STAT).
OUT ON will respond with “E07’ if the output cannot be turned on because of a
latching fault (OTP, AC, ENA, SO) shutdown.
5 GSAV
Save present settings. Same settings as power-down last settings listed in Error!
Reference source not found. Except the address and Baud rate are not saved
Saves to the RAM. These settings are erased when the supply power is switched off
and the new ‘last settings’ are saved.
6 GRCL Recall last settings. Settings are from last power-down or from last ‘SAV’ or ‘GSAV’
command. Address and Baud rate are not recalled so communication is not
interrupted.
