B-2 Model 146 i Instruction Manual Thermo Fisher Scientific
The instrument must be in the remote mode in order to change instrument
parameters via remote. 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. For information on changing modes, see Chapter 3,
“
Operation ”.
The commands can be sent in either uppercase or lowercase characters.
Each command must begin with the proper instrument identification
number (ASCII) character. The command in the example below begins
with the ASCII character code 179 decimal, which directs the command to
the Model 146
i , and is terminated by a carriage return “CR” (ASCII
character code 13 decimal).
<ASCII 179> T I M E <CR>
If an incorrect command is sent, a “bad command” message will be
received. The example below sends the incorrect command “set unit ppm”
instead of the correct command “set gas unit ppm.”
Send: set unit ppm
Receive: set unit ppm bad cmd
The “save” and “set save params” commands stores parameters in FLASH.
It is important that each time instrument parameters are changed, that this
command be sent. If changes are not saved, they will be lost in the event of
a power failure.
Table B–1 lists the 146 i C-Link protocol commands. The interface will
