The TwistyWriter-TTL, the TwistyWriter-232 and the TwistyWriter-485 are made up of a K663 module-based motherboard and a remote antenna.

The communication with host is made thanks to a serial link. The product name is related to the serial link characteristics:

  • TwistyWriter-TTL: RX/TX serial link at TTL level (0-5V), CMOS tolerant (0-3V)
  • TwistyWriter-232: RX/TX serial link at RS-232 level (EIA 232 : -6/+6V)
  • TwistyWriter-485: RS-485 (EIA 485) half-duplex serial link

Both cards measure 69x45mm (dimensions are shared by most of SpringCard OEM products) and are linked by a ribbon cable. The TwistyWriter-TTL, the TwistyWriter-232 and the TwistyWriter-485 motherboards can also be associated with a balanced antenna according to your size constraints or the type of tag to support. The antenna can be with one of the SpringCard’s portfolio antennas or a custom-made one.
