- Card operating distance : 0 to 8cm (depending on the card).
Connection between mother board and antenna uses either a short twisted pair wire (up to 5cm) or a 50&Omega coaxial cable for remote installation (up to 2m). Specific antenna design is possible, according to your own mechanical constraints. Contact us for information.
µSIM/SAM interfaces
- 2 micro SIM/SAM slots (ISO ID-000 format),
- Standard : ISO 7816 (3 and 4), T=0 and T=1 protocols,
- 5V or 3V smartcards (class A & AB),
- Card baudrate : up to 115kpbs,
- Gemalto GemCore chipset.
USB PC/SC interface
- Standard USB CCID profile, compliant with PC/SC version 2 specifications,
- USB 2.0 full-speed (12Mbit/s), compliant with USB 1.1, powered by the bus,
- Driver available for both Windows XP/Vista and Linux,
- Embedded APDU interpreter, giving easy access to memory contactless cards (Mifare and others) through classical READ BINARY and UPDATE BINARY commands,
- Sample software and development kit for PC/SC available freely.
Legacy mode
This product may also be used in so-called Legacy mode, for a smooth migration of applications already developed for earlier SpringCard contactless couplers (CSB4 and CSB5) :
- Standard USB CDC-ACM profile, seen as a virtual serial communication port,
- USB 2.0 full-speed (12Mbit/s), compliant with USB 1.1, powered by the bus,
- Driver available for both Windows 2000/XP/Vista and Linux,
- SpringProx API, sample software and SpringProx SDK available for registered developers.
Optional serial interface
An optional daughter board adds a standard RS-232 interface to CrazyWriter (DB9 plug).
Working with the serial interface requires an external 9 to 12V DC, 1000mA power supply (not included).
