Reason is that there is not only your instrument in the loop but also the emu41p internal virtual devices (DISPLAY, HDRIVE1, DOSLINK, SERIAL1) and the external devices (XIL) are at the end of the loop. So your instrument is not at address 1 (the default address used by OUTA/INA) and you must first SELECT it.
The recommended way is to use the FINDID command and the ID of your instrument that is LMI2200-12 according to the manual you provided elsewhere:
"LMI2200" (use the first 7 characters only)
FINDID
SELECT
then you can do the required OUTA/INA sequences.

Quote:Also strange thing, when activating ALPHA and typing command to send(before OUTA)- some symbols become *, some not, and they are in lower register(not sure if it matters), so maybe I'm not actually sending correct commands to device?

This is because emu41p, by default, load the excellent CCD-OSX ROM (a subset of the CCD module) that provides access to the full lowercase characters.
You can either remove the CCD-OSX ROM in the emu41p.ini file, or just disable the lowercase feature by using the USER mode.
