Auto_Range - BRUEL & KJAER 1050 Instruction Manual

The 'Data' (or parameters), if present, are used to further specify the Message. To
separate the 'Header' from the Data, a space SP character is used (a comma (,) will
also be accepted on read in). Data is separated by a comma (, ). Individual message
units can be sent together separated by a semicolon ( ; ). The Message specification
ends with a terminator 'Te' which could be read out as EOI with LF or ETX depending on
the setting of Address Switch 3. On read in, LF or EOI with any character is accepted as
a terminator regardless of Address Switch 3 setting.
Messages where the header ends in a '?' are output Messages and the 1050 will respond
by reading out the relevant 'data on being addressed as a talker.
A list of units accepted by the 1050 (with the minimum code underlined) are as follows:
.t!z, kHz, Hz/s
QB, dB/s, dB/s/Hz
m/s/s, m/s, mm/s, mm, 1!!!!
MILls, MIL
oct/min
in/s, in
~.
kN, lbf
§.,
ms, %, g
mV/m/s/s, mV/N, pC/m/s/s, pC/N
In general, all Messages that are read out can be read back to the 1050. Exceptions to
this rule are dynamic parameters, e.g. frequency during a sweep, Messages without
headers (by using Output_Header Exclude), or pure output Messages, e.g. Identify?.
The following sections give expanded details of the interface Messages with a short
description, examples and notes if relevant. In the examples, the full Message header is
given with the minimum code that can be sent in bold capitals.
