Section 4 Serial Controller

4.49

OUTPUT

The

OUTPUT

command sends data to the IEEE 488 bus. The Remote Enable

line (REN) is first asserted. If optional device addresses are specified, those devices

will then be addressed to listen. If addresses are not specified, the Analyzer488 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

count

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 IEEE 488 bus output terminators can be modified with the

TERM

command.

Refer to this command description for complete information.
