527 Display RF Status
Command #527 displays the current status of the RF module. The reader response
indicates whether RF is controlled externally by the host, set by command #640N RF
Control, or internally by input set by command #641 (not applicable to the MPRX). RF always
is controlled by Sense0 and Sense1 when reader is in MPRX mode. Sense0 enables RF on
antenna ports 0 and 1, and Sense1 enables RF on antenna ports 2 and 3. Refer to
“MUX
Operational Modes” on page 7–38 . Command #527 also displays the current RF status
and the uniqueness timeout.
Note: If you enter RF settings using command #642NN, the display command for RF
output frequency, F is “Fxx” and indicates use of the backward-compatible frequency
entry method.
