Instruction Manual Thermo Fisher Scientific
The analyzer ignores any command that does not begin with its
instrument identification number. If the instrument ID is set to 0, then
this byte is not required. For more information on changing Instrument
ID, see Chapter 3, “ Operation ”.
The analyzer must be in the remote mode and service mode not active
in order to change instrument parameters remotely. However, the
command “set mode remote” can be sent to the analyzer to put it in
the remote mode. Report commands (commands that don’t begin with
“set”) can be issued either in the remote or local mode, regardless of the
service mode setting. For information on changing modes, see Chapter 3,
“ Operation ”.
The commands are not case sensitive. Each command must begin with
the proper instrument identification number (ASCII) character. The
command in the following example begins with the ASCII character
code 142 decimal, which directs the command to the Model 5028 i ,
and is terminated by a carriage return “CR” (ASCII character code 13
decimal).
<ASCII 142> T I M E <CR>
Many of the commands have two forms. One form reads parameter
from the instrument’s memory, and the other writes, or updates, a
parameter. The syntax for a write command adds the word “set” in front
of the command and provides an argument. Command responses are
generally echoed with a data element appended.
Note
If the Service Mode is active, C-Link “set” commands are not
allowed. This is to prevent parameters from being changed remotely
while the unit is being serviced locally.

If an incorrect command is sent, an error message is generated. The
list of error responses is shown in Table B–1 . The following example
sends the incorrect command “set unit mg/m3” instead of the correct
command “set conc unit mg/m3.”
Send: set unit mg/m3
Receive: set unit mg/m3 bad cmd
