Further information on Preh MC140 Keyboard
A 140 key keyboard with a built in 3 track Magnetic
swipe reader (MSR), the MC140 is ideal for systems that require
a fully featured keyboard with a large number of special function
keys. The MC140 is a compact design for the number of keys that
are incorporated..
In addition the built in MSR caters for cheque/debit/credit
card processing or loyalty system. When a magnetic card is swiped,
a good read is confirmed by the LED on the keyboard and the data
read from the card is passed to the POS/PC system via the keyboard
interface as if typed.
The key map is stored on board the keyboard via
an EEPROM and is easily modified without the use of DIP switches
via a PC based DOS program. Through this unique interface and
a daisy chained standard keyboard, all keys and options of the
PC-POS keyboard can be programmed with strings, scan codes or
ASCII information. Keyboard configurations can be read from the
keyboard, modified and written back to the keyboard. Additionally,
configurations can be saved out to a file for storage and later
modification. MSR track selection can also be programmed along
with header and trailer information (especially useful for EFT
programming applications).
In operation no special software is required as
all controls and key assignments are held within the keyboard.
There are 140 single relegendable keys in a 20
x 7 matrix with the option of double (1x2) and quad (2x2) sized
keys. Blanks are also available.
