message " S tore Done" will be displayed to indicate that the settings have been stored.
Memory location 0 is the location of the defaults and cannot be stored to. Storing to it
will generate a range error.
Recalling Settings
To recall a stored setting, press [RCL] followed by a location number (0-9). After
pressing any of the units keys to enter the location, the message " R cl Done" will be
displayed to indicate that the settings have been recalled. If nothing had been stored in
the selected location or if the stored settings had been corrupted, the message " R cl Err "
will be displayed. Note that [RCL][0] recalls the default settings.

GPIB Setup

Press [SHIFT][GPIB] to display the current GPIB address. Use the spin knob to modify
the address or enter the number directly from the keypad and one of the entry keys. The
GPIB address can be set from 0 to 30.
Pressing [SHIFT][GPIB] a second time will display the last 256 characters of data that
has been received by the DS360. This display is a scrollable 3 character window into the
DS360's input data queue. The data is displayed in ASCII hex format, where each
character is represented by 2 hexadecimal digits. The most recently received character is
indicated by the decimal point to the right of the digit. Turning the spin knob to the left
moves the window earlier into the data queue; turning it to the right moves later into the
queue. The display window cannot be moved later than the last character received.

SRQ

The user may issue an user SRQ (service request) over the GPIB. Only one SRQ (user or
otherwise) can be active at a time; the host computer must acknowledge any pending
SRQ's before a new one is sent. Note that the user SRQ is in addition to the usual service
requests based on the unit's status.
To issue an user SRQ, press [SHIFT][SRQ], followed by any of the entry keys. The
message " S end SRQ " will appear prior to pressing the entry key. After the entry key is
pressed (assuming that no other SRQ is pending), the message" " S ent SRQ " will appear,
and the SRQ LED will appear. The SRQ LED will go off after the host computer does a
serial poll of the DS360.
See Chapter 4 on programming for additional information on the GPIB.

RS-232 Setup

Press [SHIFT][RS232] to display the RS-232 baud rate setting. Use the spin knob to
modify the baud rate. The baud rate cannot be entered directly from the keypad. Baud
rates supported are 300, 600, 1200, 2400, 4800, 9600 and 19.2 k.
Pressing [SHIFT][RS232] a second time will display the last 256 characters of data that
has been received by the DS360. This display is a scrollable 3 character window into the
