Local Lockout
The local lockout condition disables the front panel LOCAL key so that
pressing the LOCAL key will not return the driver to local mode. When
local lockout is in effect, the driver is returned to local under program
control.
(sending Clear Lockout/Set Local) or by turning the driver LINE switch
OFF and ON. However, returning to local by switching to OFF and then
ON, will defeat the purpose of local lockout and the system controller
will lose control.
Addressing
The driver's listen address is set by the slide switches on the rear panel.
Refer to "GPIB Addressing".
Data Messages
The state of the driver is controlled by data message on the GPIB. Data
messages include the driver's GPIB program codes. The GPIB program
codes contain information for programming the front panel functions
(except for the LINE switch). The driver receives data messages when
addressed to listen.
Receiving the Data Message
The driver responds to data messages when in remote and addressed to
listen.
Data Message Input Format
The programming data string for the driver consists of a string of ASCII
coded characters composed of one or both of the following fields:
[Adm] [Bdn]
where: A or a = general ON command; B or b = general OFF command
dm = any digits 0 through 9 (excluding dn)
dn = any digits 0 through 9 (excluding dm)
The driver responds to an alphanumeric data string such as "A12B34"
when the driver is in the remote state and addressed to listen. (The
alpha characters in the data string can be either upper or lower case).
