The device has 4G LTE wireless transmission capabilities and 2G/3G fallback in case of the
unavailability of the 4G network. In this case, the device will operating on the 3G or 2G
network. When the 4G network will be available again, the device will switch back to the 4G
network. This feature is configurable for the
WAN
interface of the device.
•
You can check the current cellular signal reception and wireless availability in the
OpenWRT
®
/ LuCi
®
system’s
Overview
menu.
•
The available APN settings will be assured by the SIM card provider mobile operator or your
mobile internet service provider. Ask them about
APN
, password,
SIM
PIN
and further
necessary information for the configuration.
•
If you want to use the device on the wired network (LAN) with RS485 option, then remove
the
WAN
interface by the
Delete
button in the
Network / Interfaces
menu. The device
will not be restarted further - even if there is no SIM card inserted.
•
The
RS485
port should be configured before usage, which can be found in the
Services
/
Ser2net
menu. There you can configure RS485 data speed rate betweeen 300 baud and
115 200 baud, but please consider that max. 19 200 baud is guaranteed to receive by the
device. Note, that we offer to use
9 600 baud
or
2 400 baud
speed rate, which is standard
and there can be guaranteed that it will work. With higher data speed rates some connected
systems can cause loss of characters/data in case of some connected device(s).
•
Note that the device is not detecting the relay connections, it is just signaling the relay switch
by the
REL.1..4
LEDs. The compatibility settings should be done at the
Router / Relay
Switch
menu.
•
Note that all relays are latching relays, which means the device remains the last switching
status (even if the power was taken). The
Relay 1
and
Relay 2
having NC, NO, COM pins
(and it has two switching mode, where the SET and RESET are also available) while the
Relay 3
and
Relay
4
having only NC and COM pins (does not have RESET, just SET).
•
Note, that the device has supercapacitor component inside, which protects the device against
possible shorter power outages. In case of a power outage - due to the supercapacitors
–
the device has enough enegy to provide a safe disconnection and shutdown (before the
supercaps will be exhausted). The same if you store the device for months without connecting
a power source or using it. Therefore, this component must be charged before usage. When
powering the device, the charge of the supercapacitors will be started automatically. The
system will be started by the device only after the end of the charge process.
