8.8. Global Output Commands
8.8.1. Description
Global commands are a way to quickly set all power supplies on the RS-232/RS-485
Digital communication 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/RS-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 Output voltage values is shown
in Table 8-6. ‘n’ may be up to 12 characters plus decimal point.
3 GPC n Program the Output current value in amperes. The range of Output current values is
shown in Table 8-7 and 8-10. ‘n’ may be up to 12 characters plus decimal point.
4 GOUT
Turns the Output to ON or OFF:
“
OUT 1/ON ” = turn On
“ OUT 0/OFF ” = turn Off, 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 (to RAM memory) per Section 5.14. Same settings as power-
down last settings listed in Section 5.14 except the unit Address and Baud rate are
not saved These settings are erased when the Power Supply 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. Unit Address and Baud rate are not recalled so communication is not
interrupted.
NOTE
The Power Supply can accept values greater than 5% of the maximum value called out in
Table 8-6, however it is not recommended to program the Power Supply beyond the rated
Output Voltage/Current values and performance is not guaranteed.
