“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.

Interval Timeout
@Transparent
The serial port will queue the data in the buffer and send the data to the Cellular

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. When a
packet length between 1 and 1024 bytes is specified, data in the buffer will be
