Command Description
PV n
Sets the output voltage value in Volts. The range of voltage value is described in Table 7-5.
The maximum number of characters is 12. See the following examples for PV n format: PV
12, PV 012, PV 12.0, PV 012.00, etc...
PV? Reads the output voltage setting. Returns 6 digit string.
MV?
Reads the actual output voltage. Return 6 digit string.
Example: 60VDC supply sends 01.150, 15.012, 50.000, etc...
PC n
(See Note 1)
Sets the output current value in Amperes. The range of current values are described in
Tables 7-6... 7-9. The maximum number of characters is 12. See the following examples for
PC n format: PC 10, PC 10.0, PC 010.00, etc...
PC? Reads the output current setting. Returns 6 digit string.
MC?
(See Note 2) Reads the actual output current. Returns 6 digit string.
Example: 72A supply sends 72.000, 20.140, 04.120, etc...
DVC?
Display Voltage and Current data. Data will be returned as a string of ASCII characters.
A comma will separate the different fields.
The fields, in order, are: Measured Voltage, Programmed Voltage, Measured Current,
Programmed Current, Over Voltage Set point and Under Voltage Set Point.
Example: 60V-10A supply sends: 60.0000, 60.0000, 05.0000, 05.0000. 66.00.00.00
Command Description
ADR n ADR is followed by address which can be 1 to 31 and is used to access the power supply .
CLS Clear status. Sets FEVE and SEVE registers to zero.
RST
Reset command. Brings the power supply to a safe and known state:
Output voltage: zero, Remote: non-latched remote,
Output current: zero, Auto-start: Off,
Output: Off, OVP: maximum,
FOLD: Off, UVL: zero
The conditional registers (FLT and STAT) are updated, the other registers are not changed.
RMT
Sets the power supply to local or remote mode:
1. RMT 0 or RMT LOC, sets the power supply to Local mode.
2. RMT 1 or RMT REM, sets the unit to remote mode.
3. RMT 2 or RMT LLO, sets the unit to Local Lockout mode (latched remote mode).
RMT?
Returns the Remote mode setting:
1. ”LOC”- The unit is in Local mode.
2. ”REM”- The unit is in Remote mode.
3. ”LLO”- The unit is in Local Lockout (latched remote) mode.
\ Repeat last command. If \<CR> is received, the power supply will repeat the last command.
