When a packet length between 1 and 1024 bytes is specified, data in the buffer
will be sent as soon it reaches the specified length.
Note: Data will also be sent as specified by the interval timeout or delimiter
settings even when data is not reaching the preset packet length.
Enable Delimiter1/2
When Delimiter 1 is enabled, the serial port will queue the data in the buffer
and send the data to the Cellular WAN/Ethernet WAN when a specific
character, entered in hex format, is received. A second delimiter character may
be enabled and specified in the Delimiter 2 field, so that both characters act as
the delimiter to control when data should be sent.
Disable
Delimiter1/2 (Hex)
@Transparent

0
Delimiter Process
@Transparent
The Delimiter process field determines how the data is handled when a
delimiter is received.
None: Data in the buffer will be transmitted when the delimiter is received; the
data also includes the delimiter characters.
Strip: Data in the buffer is first stripped of the delimiter before being
transmitted.

Modbus RTU slave: router connects to Modbus slave device which works under
Modbus RTU protocol.
Modbus ASCⅡ slave: router connects to Modbus slave device which works
under Modbus ASCⅡprotocol.
Note: When select “Modbus RTU slave” and “Modbus ASC Ⅱ slave” protocol,
router is as TCP Server site, user need to enter a local port number in “Local Port
@Modbus” and wait to be connected.
Modbus RTU master: router connects to master device which works under
Modbus RTU protocol.

Modbus ASCⅡ protocol.
Note: When select “Modbus RTU master” and “Modbus ASC Ⅱ master” protocol,
router is as TCP Client site, user need to enter slave address and slave port
number in “Slave Address @ Modbus Slave ” and “Slave Port @ Modbus Slave”,
and connect to Server site.
