Interface Operation
This chapter discusses the methods used to interface the 2000I and 2000M
DC power source instruments using the optional interface connectors RS-
BAT and IE-BAT. In general, operation of these instruments via an interface
involves the writing and reading of ASCII data to or from the instrument.
In both interfaces, the same characters are used for each command. The only
differences between these two interfaces are due to the physical
characteristics and the “built-in” commands; defined by the IEEE488
interface. In both instances, the operation of the interface is completely
disabled when the rear panel’s INTERFACE ENABLE
toggle switch is OFF
or when a front panel operation, such as baud rate or address selection, is not
initiated.
Note:
Throughout this section, it is assumed that the user is fully conversant
with manual operation of the 2000 instrument.
RS232 Interface Option
The RS232 option enables the 2000 instruments to be controlled or
interrogated by any RS232 interfaced computer or terminal. A modem
telephone link enables control or interrogation to be performed remotely.
Rates of 1200, 19,200 and 2400 baud may be selected. This interface is fully
isolated from the analog circuitry of the instruments for voltages of up to
500V.
When the RS-BAT interface is fitted in the instrument, an additional
selection is available when commanded by the MNU key.
