State
field - choose the right protocol type here:
-
off: no dataflow
-
raw: full duplexity
-
rawlp: one-direction communication
-
telnet: for further usage
We offer to use the
raw
option here, because the meters are sending raw text format files to the
modem.

default value is 30 (0 means without delay).

-
Baudrate
(default is
9600 bps for the RS485) can be defined between 300 bps and 115 200
bps.
-
Stopbit
value
can be 1 or 2
-
Databits
value
can be 7 or 8
-
Parity
value can be EVEN, ODD or NONE
Examples:
For standard speed 7E1 mode use this command:
9600 1STOPBIT 7DATABIT EVEN
For lower speed 8N1 mode use this one:
2400 1STOPBIT 8DATABIT NONE
Important!
Note that maximum 115 200 baud speed rate can be used wheather of the
configuration options.
But, we offer to use the standard 9600 baud or 2400 baud speed
rate for receiving or transmitting data without character / data loss.
The incoming RS485 data are not stored locally, they will be transparently transmitted from the
device through the cellular network.
Note, that you should add the specified RS485 port number to the
Firewall
rules (
Network /
Firewall
menu), otherwise the router will not receive any data.
You can also specify additional members, such as
hardware flow control with the
RTSCTS
, which
can be turned off with the "
-
" prefix. A
space
character must be placed between members.
When you modified the settings, save them by the
Save & Apply
button.
