The RS-232 protocol allows some flexibility in its implementation.
Table 3-6 lists certain RS-232 values that are required by the 3000ZA
implementation.

Message Interval
Range ID Relays: There are three dedicated Range ID relay contacts.
Three ranges are assigned to relays in ascending order—Low range is
assigned to Range 1 ID, Medium range is assigned to Range 2 ID, and
High range is assigned to Range 3 ID.
Network I/O: A serial digital input/output for local network protocol.
At this printing, this port is not yet functional. It is to be used in future
options to the instrument.
RS-232 Port: The digital signal output is a standard RS-232 serial
communications port used to connect the analyzer to a computer,
terminal, or other digital device. It requires a standard 9-pin D
connector.
