3.4.1.2 REMOTE STANDBY
A standalone unit or a multiple unit configuration (parallel, series or series-parallel) can be set to
STANDBY status by applying a remote signal to the TRIGGER PORT as shown in Figure 3-15.
For multiple unit configurations this signal must be applied to the master. When the signal is
momentarily active (short or logic 0 for a minimum of 100 microseconds), the output is set to
OFF after a maximum delay of 200 milliseconds and the STANDBY indicator goes on. Depress-
ing the STANDBY key or sending the OUTP ON command via the remote interface restores the
unit to the previous state and the STANDBY indicator goes off.

3.4.2 VOLTAGE/CURRENT MODE CONTROL
The mode of operation, voltage or current, can be programmed externally by applying a signal
at pin 2, referenced to pin 9, of the Analog I/O port. Applying a TTL logic 1 (or open circuit) pro-
grams the unit to voltage mode. Applying a TTL logic 0 (or short) programs the unit to current
mode.
To be functional this feature must first be configured from the front panel. From the power-up
screen press
$ to enter the Analog Remote Setup menu (see Table 3-15). Highlight External
Mode, then press
!
, highlight Enable and press
$
. Press
%
to apply the changes (without
saving for power-up) and exit to the power-up screen or
#
to abort. The Save/Recall feature
(PAR. 3.3.8) can also be used to restore this setting upon power-up.
3.4.3 CONTROLLING THE OUTPUT USING THE BOP AS A POWER AMPLIFIER
The BOP can function as a power amplifier by means of the External Reference input at the
Analog I/O port. This analog signal controls the main channel of the BOP. To use the BOP as a
power amplifier see the following instructions for using the external reference: PAR. 3.4.3.1 for
fixed gain, PAR. 3.4.3.2 for variable gain by establishing the maximum full scale output.
