If the STAT LED blinks red and green alternately, it indicates the following:
If the STAT LED is blinking red , it indicates the following:
PPP LED
The programmable PPP LED must be set to PPP (the default) in order to indicate the current state of a PPP
connection. For more information on programming the PPP LED, see the
PAC Manager User’s Guide
(form 1704) or the OptoMMP Protocol Guide , (form 1465).
On Wired+Wireless models, the PPP LED is replaced by the WLAN LED. These models can still communicate
using PPP even though they do not have the indicator.
The PPP LED blink codes are as follows:

Means
Green Solid There is a PPP connection.
Green Slow A PPP connection is being established.
Orange Solid The controller is listening on its PPP port.
Orange Slow
PPP is disconnecting. After disconnecting, if Incoming PPP is enabled in PAC Man-
ager, PPP listens for incoming calls. Otherwise, PPP enters Idle state (from which it
can initiate an outgoing call). To configure PPP, see the
PAC Manager User’s Guide
.
Red Slow The PPP service has been instructed to stop and is shutting down.
Off n/a The PPP connection is idle or disabled.
