Communication Reader-Host Rev. 1.2 February 1999<br />
3.7.40 RWD_Set_HF_Mode<br />
This command sets the read/write device into Proximity or Long Range Mode.<br />
In standard applications (e.g. using standard reader hardware from Philips) RWD_Set_HF_Mode<br />
is not used because the HITAG Communication Controller automatically sets the right mode<br />
after power-up.<br />
Examples:<br />
• SetHFMode setting the mode to Long Range sets a Proximity Reader in a powerdown-state<br />
with reduced power consumption.<br />
• SetHFMode can be used in a system with a Proximity RF-part and a Long Range RF-part to<br />
select one part at a time.<br />
C-Function: void RWD_Set_HF_Mode (BYTE_T mode);<br />
