2 blinks every
second, followed by
a 1 second pause
–
Not able to connect
to network
Initially indicates the device is attempting to connect
to Wi-Fi
®
network. If this status continues, the device
is unable to connect to the network.
To resolve, repeat the setup process and re-enter the
SSID and password. If the problem persists, check
the following:
•
The monitor
CAN ONLY CONNECT TO 2.4 GHZ
Wi-Fi
®
signals. Most Wi-Fi
®
routers provide
several frequency channels. Make sure you are
connecting to the 2.4 GHz channel.
•
The monitor does not have the capability to
connect to public networks that require a second
step of browser authentication, such as a free
public hotel or airport network. A different
network will need to be chosen.
•
Some corporate networks require the device
MAC address for security. This can be found on
the serial number label of each monitor.
•
Additionally, the following firewall ports need to
be available:
a. DNS: 53 (UDP)
b. SNTP: 123 (UDP)
c. HTTPS: 443 (TCP)
d. MQTT: 8883 (TCP)
