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:
232 LED
The 232 LED indicates the following:
