ReaderEnable
There are two connections that can be used to enable the reader. The Serial connector
provides access to the ReaderEnable1 signal. The GPIO connector provides access to
the ReaderEnable2 signal. At least one of these signals must be pulled to greater than
+2V for the reader to be active. These signals can be used to remotely turn the power off
for power savings. The ReaderEnable Jumper Terminator provided with your reader will
connect pins 4 and 5 of the GPIO connector providing +12VDC to the ReaderEnable2
input.
