Suspend Mode - Elatec TWN4 MultiTech 2 Series User Manual

Within the two seconds timeout, where the red LED is blinking, the transponder, which just has been
recognized will not be accepted again. This prevents the reader from sending identical IDs more than
one time to the host. If during the two seconds timeout of the red LED a different transponder is
detected, the complete sequence restarts immediately.

SUSPEND MODE

Only applicable for USB version of reader modules:
The USB version of readers support the USB suspend mode. If the USB host signals suspend via the
USB bus, the reader turns off most of its power consuming peripherals. During this operation mode,
no detection of transponders is possible and all LEDs are turned off. Once the host resumes to normal
operation mode, this is also signaled via the USB bus. Therefore, the reader will resume to normal
operation too.
