2.11 Auto-tune Operation
The MaxiProx is tuned correctly when the Auto-tune LED is green. If the LED is red, use a spacer to
position the reader at minimum of 4 inches away from metal in the mounting surface.
2.12 Reader Testing
Apply Power to the reader and the LED will display a sequence of flashes and beeps, indicating the
LED control mode. Two flashes of green and two beeps followed by a short delay, then one additional
flash (beep), is the correct sequence for "Green Flash/Beep on valid read” (SW1-5 off). Three initial
green flashes and beeps followed by a pause and then one additional beep indicate no Green
Flash/Beep on valid read (SW1-5 on).
2.13 Power-Up Tune
Following this initial power up sequence the reader will perform power-up Auto-tune. It will beep and
turn the access LED amber for ~1 second to indicate that a power-up tune test is about to begin. It will
then attempt to tune. If it successfully tunes, it will give two quick beeps and a green on the access
and tune LED's to indicate the reader is tuned. If unsuccessful, the unit will give a single 1.5-second
beep with a red on the access and tune LED’s. If Auto-tune is not successful, the installer should
check for large areas of metal less than 4 inches from the back of the unit.
2.14 Periodic Auto-tune
Periodic Auto-tune retunes every 1-minute.
2.15 Supervisor Mode
During idle periods in normal operation, a periodic supervisor 1-byte transmission is sent to the host
controller over the Wiegand interface every 1 minute. Supervisor Mode is only available in Wiegand
Interface Mode.
