TwistyWriter (TTL, 232 or 485)
Serial interface contactless reader (coupling device), remote antenna
The SpringCard TwistyWriter-TTL, TwistyWriter-232 and TwistyWriter-485 are based on the K663 module. Communication with host is a serial link, depending on what you need:
- 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
The modules measure 69x45mm and need a symmetric (balanced) antenna depending on your size constraints and on the type of tag to support. Have a look in our antennas portfolio or ask for a custom-made one. Your SpringCard contact will also guide you to the ribbon cable you need.
Here is the presentation of the TwistyWriter TTL, 232, 485 in video.
