Readers & Writers

Our reader / writers are self contained interface units that you can connect to a host PC or CPU using RS232 or USB. The units are available to work with the full range of keys and tokens and come supplied with a communication cable, set-up software and a user manual. Both desktop and panel mount versions are available as well as all mounting hardware and accessories.

The KeyLink III/SlimLink III Reader/Writers are the standard Reader/Writers for all new applications. These readers were specifically designed to optimise throughput speeds when used with our SPI-Flash devices, but also support interchangeable use of all our standard serial memory Keys/Tokens – including those that utilise the Microwire, I²C and SPI interface protocol.

KeyLink III/SlimLink III Reader/Writers come with a USB interface and are ideal for development and production programming purposes.
