PD-320 - what is the encoding of the customer's display?

Question

Iron

There is such equipment, called "Customer's Display", model PD-320 (stripped down, neutered model of the 2300th model). As it turned out, the encoding of Cyrillic characters in this rubbish does not comply with any standard and any known encoding of older models. And there are no switches in the controller. The task is to put it on a Linux-based POS terminal that easily supports 2200-2800 models, but does not support 320.
The piece of iron works, displays the characters as it should, it displays all the first 127 standard characters (in other words, Latin characters and special characters), but the Cyrillic alphabet is in complete disarray.
This piece of iron also does not have documentation, instead of it they slip documentation on the PD-2800/320, where 90% of the information corresponds to the older onemodels. (Switch jamer is NOT in 320)
320th adequately displays characters under windows with Atolov closed drivers. But I need to slap this fool into Linux.
There are people who met with this miserable iron? Does anyone have a symbol table for this device?

Answer 1

In order for the customer's display of the PD-320 to show in Cyrillic, you need to configure the Switch (jumper) on Epson. There is a small cover on the back of the display at the bottom, remove it and you will have 6 switches.
1.ON 2.OFF 3.ON 4.OFF 5.OFF 6.OFF .
