SECTION 3 - OPERATION
3.1 GENERAL
This section explains how to operate the 1000 Watt BOP-GL Power Supply. The power supply
can be operated using either a) signals applied to the Analog I/O port control or b) digital com-
mands via either the GPIB or RS 232 bus or c) a mixture of both.
Analog control (see PAR. 3.4) uses signals from the Analog I/O port to set the main channel
mode (voltage/current), control the output voltage or current, set protection limits, and uses a
signal applied to the Trigger port to control whether the output is on (enabled) or off (disabled).
Digital control (see PAR. 3.6) uses either the built-in GPIB (IEEE 488) (see PAR. 3.6.5) or RS
232 (see PAR. 3.7) interface to communicate with a remote computer. GPIB or RS 232 commu-
nication is via SCPI commands which afford full functionality of the BOP (see PAR. 3.7, Appen-
dix A and Appendix B). Operation using digital control can be simplified by the use of the VISA
driver (see PAR. 3.6.5).
3.2 POWER-UP SETTINGS
CAUTION: Before connecting a load, note that the unit is will power-up with the configu-
ration set by the power-up switches accessible through the top cover (see
Table 2-2 for switch settings). Verify that these power-up settings are com-
patible with your load (see Figure 2-2 and Table 2-2 for switch settings).
To change to change load type, baud rate or Trigger port Remote on/off logic
refer to PAR. 3.3.2.1; to change all other power-up settings listed below refer
to PAR. 3.3.2.2.
In addition to the power-up settings determined by the switches accessed
through the top cover, many unit parameters may be saved for the next
power-up cycle using MEM:UPD commands (see PAR. B.12). When using
MEM:UPD, it is recommended that the unit be tagged with the custom power-
up configuration to avoid unexpected behavior upon power-up.
Factory default power-up switch settings (Figure 2-3) are BOLD (other choices are in italics):
• Load type Active (Battery, Resistive)
• Trigger port pin 2 remote on/off logic set for:
logic 1 or open = output enabled, logic 0 or short = output disabled
(logic 0 = output enabled, logic 1 = output disabled)
NOTE: By using the OUTP:CONT command (see PAR. B.15), the Trigger port pin can be set
to put the unit in standby, or this input can be completely disabled if using OUTP com-
mand to control whether output is on or off.
• RS 232 Baud rate 9600 (19.2K)
• Standalone configuration (Master, Slave)
• Analog Control enabled (disabled)
