4.5- Serial Settings >> Serial portX
The MTX-Router-Titan-3G and MTX-Router-Titan-3G-mini devices have several serial ports and a USB
port. Using these, we can create serial/3G, USB/3G or serial/CSD gateways to remotely control serial
devices. The number of RS232 or RS485 serial ports will depend on the MTX-Router-Titan model used.
Baudrate
: specifies the serial port velocity (115200, … , 300)
Data bits
: specifies the number of data bits (7, 8)
Parity
: specifies the parity (none, even [par], odd [impar])
Stop bits
: specifies the number of stop bits (1, 2)
Flow Control:
specifies the flow control (none, hardware)
Timeout ms:
indicates the time (in milliseconds) that the device must wait without receiving
data in its serial port before sending the data via IP. If a value of “0” is specifies (the default
value), the data will be sent as they arrive in the serial port. A value of 10 for example means
that the data will not be sent until 10ms have passed without receiving serial ports. This allows
the data to be received at the destination less fragmentated.
Allow embedded AT Commands:
by selecting this check box, embedded AT commands can
be sent in a 3G-Serial gateway in either Server or Client mode. The AT commands must be
sent between the tags <MTXTUNNELR> and </MTXTUNNELR>. For example, if we want to
obtain the network coverage, the following command can be sent:
<MTXTUNNELR>AT+CSQ</MTXTUNNELR>, or if we wish to remotely reset a device, we can
send the following command: <MTXTUNNELR>AT^MTXTUNNEL=REBOOT
</MTXTUNNELR>
Allow incoming GSM calls
(CSD Data Call)
:
by selecting this option, we accept CSD calls via
serial ports. This is only valid to work when the port is configured as a gateway of the TCP
Server or TCP Client type, and when the MTX-Router-Titan-3G or MTX-Router-Titan-3G-mini
device is configured to work in 2G mode. When a CSD call is received and accepted, the 2G
connection is suspended until the call ends. Only one serial port can be specified with this
option
Useful for metering applications. Consult the examples in the Annex for a better understanding.
This option (CSD data call) is not available for 3G models with GPS or 4G models.
Function: Nothing or Used by External Device
: select this option if you do not wish to use
a specific serial port (such as IP/serial gateway) or if you do not want the port to be used by an
external device specified in the configuration section “External Devices”. For example, if you
wish to use a temperature sensor, a distance sensor or any other device specified in the
“External Devices” section, you must select this option.
Function:
Serial – IP Gateway
(TCP Server)
: select this option if you wish to create a
Serial-3G/2G transparent gateway in TCP server mode; i.e. a scenario in which the MTX-
