7. If analog programming is to be used, connect the programming device to the master as
shown in Figure 2-6.
8. If analog control is to be used, the multiple unit combination is ready for use. Operation of the
multi-unit combination is identical to a standalone unit.
NOTE: When powering down the system, the master should be the last unit turned off.
9. If digital control is to be used, turn all units off.
a. Set power-up switch S3-2 to 0 (analog input disabled), Connect the GPIB or RS 232 cable
from the host computer to the GPIB or RS 232 port on the BOP, respectively.
b. Turn on all units, starting with the master. After the start-up sequence has completed, ver-
ify that
• all POWER/FAULT/LIMIT lights green,
• MASTER/SLAVE lights correctly indicate master (green) and slave(s) (yellow)
• It is recommended that the Output on-off pin at the Analog I/O port be disabled by send-
ing OUTP:CONT OFF command to the master. This allows OUTP ON and OUTP OFF
commands to control the output digitally via the host computer. The DIG. CTRL light on
the master front panel will be on (green).
• All OUTPUT ON lights for the slaves are on (green). The master OUTPUT ON light sta-
tus is determined by either the state of the signal at Trigger port pin 2 or an OUTP com-
mand (see PAR. 3.3.9 for details).
