Measurement Computing Micro 488/EX rev.2.1 - Manual (Page 123)

Section 5 Command Descriptions
5.53
OUTPUT (Controller mode)
The OUTPUT command sends data to the IEEE bus. The Remote Enable line is
first asserted if the Micro488/EX is the System Controller. If device addresses are
specified, those devices will then be addressed to listen. If addresses are not specified,
the Micro488/EX 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 then exactly that number of
characters will be sent to the bus devices. Otherwise, OUTPUT terminates data
transfer upon detection of a serial CR of LF terminator from the serial input. The
serial input terminator(s) are replaced with the bus output terminator(s) before being
sent to the bus devices.
The number of characters that can be set to a bus device is limited by the
available USER heap. The exception to this is OUTPUT #count, in which the number
of bytes is limited to 65,535.
The IEEE bus output terminators can be modified with the TERM command.
Refer to this command description for complete information.
SYNTAX OUTPUT[addr[,addr…]][#count];data
or
OU[addr[,addr…]][#count];data
addr is a bus device address. Up to 15 addresses may be specified.
count is the number of characters to OUTPUT.
data is a string of characters to OUTPUT terminated by the serial
terminator(s). (unless count is specified in which case no
terminator is needed).
