When using the RK40 iCLASS Pin Reader with the D9210C or D9210B Access Control Module, the reader must be configured for 26-bit output. The ARD-RK40-14 comes pre-configured for 26-bit output. The ARD-RK40-09 must be reconfigured with the configuration card pack from HID because the -09 readers are 8 bit. The configuration card pack can be ordered from http://www.hidglobal.com/literatureRequestForm.php.
While filling out the form, in the Comment text box indicate you want the iClass Configuration Card Pack. You can request the card pack sent overnight if you supply them with your UPS number. Otherwise,HID ships it ground shipping.

****CAUTION**** Upon a power cycle to the reader, there is an interval of approximately 1 min during which if you enter a 3-digit code followed by #, the master site is changed for that reader. This will cause codes with different site codes to appear invalid and be rejected by the reader. Be careful not to change the site code accidentally after a power cycle.
