Setup of 28-key POSkeyboard (DM-KX028)
A 28-key POS keyboard unit (DM-KX028) can be used by connecting to the LCD unit of IR-700,
which has a total of 28 keys in 4 lines horizontally and 7 lines vertically. Also, it can be used by
connecting an MSR (Magnetic Stripe Reader) unit.
The 28-key POS keyboard unit is enabled by writing definition data into the POS controller in
the LCD unit of LCD 700. This definition data can also be used in another IR-700 by saving as a
file.
The POS controller is connected to the USB port in the inside of IR-700. When it receives key
input from the 28-key POS keyboard unit, it outputs the defined data. This data is input into IR-
700 as a character string, just as with a USB keyboard.
Since data is not saved in the 28-key POS keyboard unit, you can use it without changing the
definition data if you replace the keyboard. However, resetting of the definition data is required
when the LCD unit is replaced.
The definition data of IR-320/310 can also be read in as a definition file for the IR-700.
It can also be used by switching, with the layer change key, or in software, by assigning several
definition data to one key, with the layer function.
Note:
Do not input data from an input device (external keyboard, POS keyboard, etc.) connected to the keyboard
interface, during data input from the 28-key POS keyboard unit and the MSR unit.
The 28-key POS keyboard unit cannot be connected to the 15" Display model.
