This section defines settings for configuring the analog output interface, including mode selection (voltage or current), test output values, scaling (gain), and offsets.

mode |
Mode for analog output (volt or current). |
volt |
ENUM |
volt, current |
|
|
value |
Value of test voltage or test current. |
5.0 |
Single |
[0,100] |
|
|
test |
If on is selected, test value is used. |
on |
ENUM |
on, off |
|
|
gain1-6 |
Scaling between output parameter value (e.g., roll) and analog output value (e.g., voltage). |
1.0 |
Single |
[0,100] |
Six individual gain settings available. |
|
offset1-6 |
Offset between output parameter value (e.g., roll) and analog output value (e.g., voltage). |
0.0 |
Single |
[0,100] |
Six individual offset settings available. |
|
checksum |
use checksum in serial port communication with analog junction box. |
on |
ENUM |
on,off |

Note: The checksum was introduced in MRU firmware v. 2.7.15. Older junction boxes, versions 3.0 and 3.1, do not support it. Ensure checksum is off if the MRU connects to an old junction box.
Example:
Examples of 'get' and corresponding 'set' commands within the analog domain are provided below.

|
get,analog,mode<CR><LF> |
set,analog,mode,volt<CR><LF> |
|
get,analog,value<CR><LF> |
set,analog,value,2.1<CR><LF> |
|
get,analog,test<CR><LF> |
set,analog,test,on<CR><LF> |
|
get,analog,gain1<CR><LF> |
set,analog,gain1<CR><LF> |
|
get,analog,offset1<CR><LF> |
set,analog,offset1,0.5<CR><LF> |
|
get,analog,checksum<CR><LF> |
set,analog,checksum,off<CR><LF> |
To check if the analog output is enabled, use this command:
get,analog<CR><LF>
then
set,analog,on<CR><LF>
will enable analog output protocol on the RS-485 port.
set,analog,multi<CR><LF>
will enable the use of RS-232 streamer as normal while the analog output is set to a fixed output structure.
set,analog,off<CR><LF>
will disable the analog output.
