Illuminates steady red when power is applied.
Illuminate steady when there is a network connection to the
associated LAN port and flash when data is transmitted or
received.
These indicators display the wireless WAN status as follows:
NET – Illuminates green when a wireless network has been
detected.
SIM – Illuminates green when a valid SIM card is installed in the
unit.
DAT – Flashes green when data is being transmitted or received.
The three indicators labelled SIGNAL illuminate to indicate the
wireless signal strength as follows:
None illuminated
1 LED illuminated
2 LED‟s illuminated
3 LED‟s illuminated
On the Transport SR models with a PSTN interface, these
indicators operate as follows:
OH – Illuminates green when the modem has gone off-hook.
CD – Illuminates green when the unit has connected to a remote
modem and asserted the Carrier Detect signal at the serial port.
DAT – flashes green when the unit has connected to a remote
modem and data is being transferred.
These indicators operate in one of two software configurable
modes:
Connection Mode: Illuminate steady if a terminal is connected to
the serial port and the DTR signal is on. Flash when data is
transmitted or received.
DTR Mode: Flash when data is transmitted or received only.
< -113 dBm (effectively no signal)
