Digital Input/output Lines

There are no front panel controls or annunciators for the digital input/output (I/O) lines, I/O 7 to I/O 0. Connection to the eight I/O lines is via the rear panel DIGITAL I/O connector. If a logic low is applied to any line, the instrument treats it as an input; if the instrument sets a line to logic low, the instrument treats it as an output. An output low condition takes precedence over an input high condition. All digital I/O lines are controlled by a computer interface (see Chapter 4, "Computer Operations"); however, as a default, lines I/O 7 to I/O 4 are used to output alarm status conditions for channels 4 to

20(see Table 2-5). An instrument-generated I/O line alarm output takes precedence over any other configuration.

All Digital I/O lines are set high (non-active) whenever power is cycled. These lines remain high until an alarm condition or computer interface command changes an output state.

Note

Measurements taken with the Monitor function do not affect the digital outputs.
