Indicator LEDs
There are five Indicator LEDs that signal power and I/O activity and are visible from the outside cover.
The Power LED is blue when power is correctly applied to the TCNM-ACBB1 and the power switch is
turned on. This LED is red if power polarity is incorrect. In this case, the connected reading device and
optional Backup Module are protected.
If external I/O devices are powered through TCNMACBB1(connected to
+V/-V), they are not protected from polarity inversion.
The remaining four LEDs signal activity on the relative I/O lines. Their meaning depends on the software
configuration of the connected reading device.
