INTRODUCTION 2 Thank you for choosing this innovative product. This keyboard is one of the SK-3320 series products, which are 104/105/106/107/109 keys enhanced keyboards for IBM PC/AT, PS/2 and its compatibles. And integrated a smart card reader in it. OPERATION 3 3.1 PC/AT, PS/2 This keyboard is designed to be AT,PS/2 mode Mode Selection Selection is done by auto-switchable. Smart card Reader Carder is designed in RS-232 interface. 3.2 Mode Indicators 3.
3.4 Thematic Delay and Repeat Rate 3.5 Pseudo N-Key Roil-over Capability 3.6 Diagnostic Test With the exception of the Pause key, all keys are thematic. When a key is pressed and held down, the keyboard delays 0.5 sec. and begins sending a make code for that key at a rate of 10.9 characters per second. (The delay is called thematic Delay and the rate is called Repeat Rate.) If two or more keys are pressed, only the last key pressed is repeated at the repeat rate.
CABLE AND CONNECTOR The keyboard shielding cable long cable. The keyboard cable is connected to the host unit through a Din connector . The smart card reader is connected to host unit through a DBY connector. The following figure lists the connector pins and their signals.
