Product family
K531-TTL or K632-TTL
- Serial communication at TTL level (RX/TX at 0/5V),
- Baudrates : 38400bps (default), 115200bps or 9600bps.
K531-232 or K632-232
- Serial communication according to RS-232 standard (RX/TX at +12/-12V),
- Baudrates : 38400bps (default), 115200bps or 9600bps.
- Note : K531-232 offers same functions as our desktop reader CSB4-S.
K531-485
- Serial communication according to RS-485 standard (bus A/B),
- Baudrates : 38400bps (default) or 9600bps.
- Note : allows long distance operation.
If you're looking for a nice housing for K531-485, take a look at our IWM-K632 reader ; this wall-mount proximity reader can also be flashed with K531-485 firmware.
Development and integration
- Unified SpringProx API, available in the developer's kit (SDK for K531&K632) ; the SDK includes ANSI C source code, to be ported on virtually any target, and Windows binaries,
- K531-232 : same platform as CSB4, thus allowing fast and easy development on a desktop computer,
- Simplified ASCII command set for instant operation from inexpensive host microcontroller.
Custom design
Need custom functions into your K531 ? We can also develop and embed a dedicated firmware into the K531 in order to gain the highest performances or to free the host from any card-related processing.
