Example of how to use the POLL command to request a specific message output type.
First configure the CS135 into polling mode as shown in the example above and exit the
terminal interface. To poll the CS135 for a particular message type, type the following.
POLL 0 113
The example text above will request the “CT25K Message 1” and should look similar to the
text below.
CT00010
10 12345 ///// ///// 00000f80
5.1.7 Loading a New Operating System
A new OS can be entered with the LOADOS module command. Note three
different modules each have their own OS. The parameter module loads a new
operating system into different modules as follows:-
Module =1, DSP (file type *. ldr)
Module =2, TOP (file type * . hex)
Module =3, PSU (file type*. hex)
The new OS must be sent using xmodem protocol.
For
example, to load a new DSP operating system:-
Enter terminal mode by typing “Open 0” (for a sensor with the default ID “0”)
This will return the prompt “CS135>”
Type the command “LOADOS 1”
The CS135 will respond:-
“Load OS into DSP
DO NOT REMOVE POWER DURING OS UPDATE!!!
Waiting for xmodem”
At this point use your terminal emulator to send the appropriate file.
Loading the OS could take a few minutes.
When the process is complete the CS135 will return the message
“Wait 40 sec for OS to restart” after which it will resume operation according to the
previously set operating parameters. It will no longer be in terminal mode.
5.2 Restoring Factory Defaults
Factory defaults can be restored using the terminal mode command
“DEFAULTS”. Alternatively, they can be set using a push switch on the DSP as
shown in Fig 5.1. The cover and enclosure lid first have to be removed. Please
refer to Sections 4.6.1 and 4.6.2.
