Color Status
Lit Power is being supplied.
Not lit Power is not being supplied.
Lit Error output is ON: Wireless device error, wireless communications
error, or host network error has occurred preventing normal
I/O communications.
Not lit Error output is OFF: Causes of the above conditions have been
removed.
Lit A fatal error has occurred that cannot be recovered from, such as a
watchdog timer error, EEPROM error, or hardware error. Replace the

0 to 9 lit Displays the received signal strength in 10 levels. The field strength is
determined by the number of indicators lit: weak for a small number
and strong for a large number.
Flashing Special function operation has completed.
Lit/not lit Input or output signal ON/OFF status (0 to 7, 8 to 15)
