Global Output Commands
7.8.1. 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.
NOTE
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 a power supply.
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 7-3. ‘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 7-4. ‘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
section 5.13. 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.
