CONTROLLING THE OUTPUT USING EXTERNAL (ANALOG) SIGNALS (REMOTE)
How do I control the mode using an external signal?
$
, highlight External Mode,
!
, highlight Enable,
$
, then
%
to apply
changes and exit or
#
to abort . This setting is not saved for power-up (PAR. 3.3.9). Select mode by applying either logic 1 or open circuit
for voltage, or logic 0 or short circuit for current, to pin 2 referenced to pin 9 of the Analog I/O port (PAR. 3.4.4).
How do I use an analog voltage to control the output (main channel)?
$
, highlight Reference input,
!
, highlight External
then
$
, then
%
to apply changes and exit. This setting is not saved for power-up. Apply ±10V signal to pin 11 referenced to pin 4 of the
Analog I/O port to control active channel (voltage or current) (PAR. 3.4.4.1).
How do I use an analog voltage to control the protection channel?
$
, highlight Protection Limit,
!
, highlight External then
$
, then
%
to apply changes and exit (not saved for power-up). Apply +1V to +10V signal to the following pins referenced to pin 12 of the
Analog I/O port to control limit channel from 10% to full scale: –Current Protect: pin 5, +Current Protect: pin 13, –Voltage Protect: pin 6,
+Voltage Protect: pin 14 (PAR. 3.4.5).
How do I choose between local, digital and analog control of the output?
The unit normally powers up in Local mode. Sending
a command via RS 232 or GPIB interfaces automatically puts the unit into Remote mode. Press
!
to restore Local mode. If an analog
voltage is controlling the output (see above), local control of the main channel is disabled and digital commands are not accepted.
How do I use the BOP as an amplifier?
See above to control the main channel and/or protection channel using analog signals. The
nominal (inherent) voltage gain of each model is calculated by (G
NOM-V
) = E
Onom
/ E
REF
. and nominal (inherent) current gain is (G
NOM-I
) =
I
Onom
/ E
REF
where E
REF
= 10V (see PAR. 3.4.4.1).
How do I control the gain of the BOP when used as an amplifier?
$
, highlight Reference input,
!
, highlight ExtlRefLevel
then
$
, then
%
to apply changes and exit (not saved for power-up). Apply ±10V signal to pin 11 referenced to pin 4 of the Analog I/O
port. Main channel setting (SET) determines gain (G) by G = SET/10 (PAR. 3.4.4.2).
CONTROLLING THE OUTPUT USING DIGITAL INTERFACE (REMOTE)
How do I use the GPIB interface to control the power supply (MG, MGL Models)?

to apply changes without
saving for power-up (see PAR. 3.5.3.2).
How do I use the RS 232 interface to control the power supply?

to save for power-up. (PAR. 3.5.3.2.2)
How do I use the LAN interface to control the power supply (ME, MEL models)?
Enter BOP IP address in web browser to
open LAN interface UNIT DESCRIPTION (home) page. Click OPERATE INSTRUMENT to control the BOP. Click CONFIGURE LAN to
change LAN settings. Click ID INSTRUMENT to blink BOP rear panel LAN indicator. (PAR. 3.5.7)
