"TYP" - Type/Model Number Query

This query is sent to the unit in order to identify the unit type by its model number / part number. No data shall be sent

with this query.

The unit will reply to this command with an ACK attention code. The DATA eld should be translated to an ASCII text

string which indicate the specied Type/Model Number, e.g: "HD17T21MMCMJDOABA".

FYI: Which translates to "HD 17T21 MMC" (http://www.hatteland-display.com/panel_computer_hd17t21mmc.php) with

a conguration added to it by using the letters "-MJD-OABA". The meaning of "-MJD-OABA" can only be found in the

description eld of invoice documents and service documents. In this example the exact description for the unit is:

"17.0" MMC IntelQM57 CEL 1.86GHz 2GBRAM 250GBHDD OSNone ACDC Bonded Black GDC Buzzer"
