• Outgoing Connections
: allows you to specify if from the MTX-StarEnergy-M it is possible to give
Internet access to all IP addresses or only to authorized IP addresses
ADDITIONAL NOTES
•
Once the configuration is finished, press the “SAVE CONFIG” button to save the changes.
Remember that you must restart the device for the new changes to take effect
•
If you use “Outgoing connections” restrictions, remember that you need to specify the IP
address of the DNS server to use.
•
If you need more than 3 authorized IP addresses, you can specify more than one IP address in
any box, separating these by “,”

Serial Settings: Serial portX
From this section it is possible to configure a CSD/2G/3G/4G-RS232/RS485 transparent gateway to
remotely access serial devices, such as electricity meters.
• Baudrate
: specifies the speed of the serial port (115200,…, 300)
• Data bits
: specifies the number of data bits (7, 8)
• Parity
: specifies parity (none, even [even], odd [odd])
• Stop bits
: number of stop bits (1, 2)
• Flow Control
: specifies flow control (none, hardware)
• Timeout ms
: indicates the milliseconds to wait without receiving data through the serial port
before sending the data through IP. If you specify a “0” (default value), the data is sent via IP
as it arrives through the serial port. A number, for example 10, specifies that no data is sent
if there is not a minimum period of 10ms without receiving data through the serial port. This
allows data to reach the destination without the fragmentation problems common in some
protocols and data management platforms
• Allow incoming GSM call (CSD Data Call)
: selecting this box indicates that a CSD type call
is accepted. Only valid to work when the MTX-StarEnergy-M is configured to work in GPRS
(2G) mode. In this mode, when a CSD data call is received, it is accepted as long as a 2G-
RS232/485 gateway is not currently established. If so, the CSD call is rejected. In other words,
once a 2G-RS232 gateway is established, it takes precedence over the CSD call
• Function
: Nothing or Used by External Device: select this operation option if you do not want to
use a certain serial port (such as IP/serial gateway)
• Function
: Serial – IP Gateway (TCP Server): select this operation option if you want to establish
a transparent CSD/2G/3G/4G-RS232/485 gateway, that is, a scenario where the MTX-
StarEnergy-M device is at the it listens on a specific TCP port waiting to receive a connection to
establish the gateway. It is the usual function for metering applications
• TCP Local Port
: TCP listening port for the Serial gateway - 2G/3G/4G
• RTS Line
: allows you to select whether the RTS line will be active as long as a socket is
connected. By default Always on. RTS line is not usually used in metering applications
