Communication Reader-Host Rev. 1.2 February 1999 3.7.26 RWD_Poll_Kb_Tags This command polls once for a transponder in the RF-field of the read/write device antenna and reads the keyboard-buffer and the digital inputs IN1 and IN2. The read/write device does not enter the Permanent Reading Mode. Port 0 of the HITAG Communication Controller is used to connect a keyboard-matrix. See document „HT RC100 HITAG TM Communication Controller“ for information about hardware connections and key-decoding. ATTENTION: To use the keyboard-decoding function a special hardware with connected Port 0 signals is required (Port 0 signals are not available on pin connectors of Philips Core Modules).
