Personal488 User’s Manual, Rev. 3.0 III-299
EXAMPLES PRINT#1,"OUTPUT22;R0C0T1X" Send “R0C0T1X” to device 22.
PRINT#1,"OUTPUT;XYZ" And send it “XYZ”.
PRINT#1,"OUTPUT0602;DEF" Send “DEF” to device 6, secondary address 2.
PRINT#1,"OUTPUT06#26;
abcdefghijklmnopqrstuvwxyz"
Send the 26 letters of the alphabet without
terminators to device 6.
PRINT#1,"OUTPUT DMM;DC VOLTS" Send “DCVOLTS” to device DMM.
The OUTPUT command sends data to the I/O adapter. The Remote Enable ( REN ) line is first asserted if
Driver488 is the System Controller and AUTO REMOTE is enabled. Then, if a device address (with
optional secondary address) is specified, Driver488 is addressed to Talk and that device is addressed to
Listen. If no address is specified, Driver488 must already be configured to send data, either as a result
of an immediately preceding
OUTPUT command or as the result of a SEND command. If the character
count count is specified, that exact number of characters is sent to the bus devices. Otherwise,
OUTPUT terminates data transfer upon detection of the EOL output terminator from the user’s program.
The EOL output terminator is replaced with the bus output terminator before being sent to the bus
devices.
OUTPUT (Peripheral Mode)
SYNTAX OUTPUT [#count][term][term][EOI];data
count is the number of characters to OUTPUT .
term and EOI override the normal IEEE 488 bus output terminators.
data is a string of characters to OUTPUT terminated by the EOL output terminator
unless count is specified.
RESPONSE None
MODE *CA
BUS STATES Determined by the Controller.
REN asserted if SYS CONTROLLER and AUTO REMOTE are enabled.
SEE ALSO ENTER, TERM, TIME OUT, BUFFERED
EXAMPLES PRINT#1,"OUTPUT;DCVOLTS" Send “DC VOLTS”
PRINT#1,"OUTPUT#5;ABCDE" Send “ABCDE” without bus terminators.
In Peripheral mode, the OUTPUT command sends data to the I/O adapter under control of the Active
Controller. The Active Controller must put Driver488 into the Talk state and configure some bus
device to accept the transferred data. The Talk state can be checked with the STATUS command, or
can cause an interrupt via the ARM command. A time-out error occurs, if enabled, if no bus device
accepts the data within the time out period after issuing the OUTPUT command. If the character count
count is specified, that exact number of characters is sent to the bus device. Otherwise, OUTPUT
terminates data transfer upon detection of the EOL output terminator from the user’s program. The EOL
output terminator is replaced with the bus output terminator before being sent to the bus devices. Even
as a Peripheral, Driver488 might be the System Controller. If it is and
AUTO REMOTE is enabled, it
asserts Remote Enable ( REN ) before sending any data.
