1 x EXPANSION AREA for Optional modules:
The HT 221 computers supports a multitude of combinations and gives additional features to the unit by taking
advantage of the expansion area in front. The table below lists all modules currently available for factory mounting.
Most of the modules connects internally through USB allowing for easy driver installation and usage, others connects
directly to the internal motherboard.
For detailed pinout assignments and connector information, please review “Pinout Assignments” and “Housing /

Table below indicates how many duplicates of the same module can be installed at the same time. Due to limited
number of internal connectors, different upper/lower area size and technical limitations some combinations (with
duplicates) are naturally not possible to achieve.
