“Modbus Over Rlink” “AT Over COM” and “GPS Report”.
1. None: Router will do nothing in RS232 serial port.
2. Transparent: Router will transmit the serial data transparently without any
protocols.
3. Modbus: Router will translate the Modbus RTU data to Modbus TCP data
and vice versa.
4. Transparent Over Rlink: Router will send all data from RS232 serial port to
Robustlink, then Robustlink will forward the data to another destination
site.
5. Modbus Over Rlink: Router will translate all data from RS232 serial port to
Modbus TCP protocol data, and then send to Robustlink, after that
Robustlink will forward the data to another destination site.
6. AT Over COM: select to operate router via RS232 COM port. For example,
enter AT commands to router via RS232 COM port.
7. GPS Report: select to enable router to output GPS status data through
RS232 port.
Select from “TCP Server”, “TCP Client” and “UDP”.
TCP Client: Router works as TCP client, initiate TCP connection to TCP server.
Server address supports both IP and domain name.
TCP Server: Router works as TCP server, listening for connection request from
TCP client.
UDP: Router works as UDP client.

Multiple Server
@Transparent
Click “Add” button to add multiple server. You need to enter the server’s IP and
port, and enable or disable “Send data to serial”. If you disable “Send data to
serial”, router will not transmit the data from this server to serial port.
Note: This section will not be displayed if you select “TCP server” in “Mode”.
show Protocol
Advanced @
Transparent
Tick to enable protocol advanced setting.
This item will show up when you enable any VPN tunnel of R3000, it means
serial data can be matched to this local IP address and be transmitted or
received via VPN tunnel.
Note: when you do not enable any VPN tunnel, this item will not show up.
Interval Timeout
@Transparent
The serial port will queue the data in the buffer and send the data to the
Cellular WAN/Ethernet WAN when it reaches the Interval Timeout in the field.
Note: Data will also be sent as specified by the packet length or delimiter
settings even when data is not reaching the interval timeout in the field.
Packet Length
@Transparent
The Packet length setting refers to the maximum amount of data that is
allowed to accumulate in the serial port buffer before sending. 0 for packet
length, no maximum amount is specified and data in the buffer will be sent as
specified by the interval timeout or delimiter settings or when the buffer is full.
