Note:
Command “DATAMODE<CR><LF>” will be accepted as command “DATAMODE<CR>” and Data
Byte=0x0A.
• Unit immediately goes to datamode, so that the DTE can start sending data.
• The data received over the air goes from buffer to DTE. If you need clear the buffer before going
to datamode use the CLI command “DATAMOD<LF>”.
• If no valid CLI commands received from DTE within 1 minute, the unit will automatically switch
back to data-mode.
Note:
The data received over the air could be lost due to Rx buffer overflow if the unit stays in Maintenance
mode long time.
1.3. Software Switching to Data Route Mode
To switch to Data Route Mode the special byte-sequences with special meanings are used:
• Escape-Sequence: “####” with 20 ms guard time before and after the command characters;
• Escape-Acknowledge: “@00<CR><LF>”.
1.4. Return from Data Route Mode
• Command “MCU CLI OFF<CR>” returns modem from Data Route Mode.
• Unit immediately goes to datamode, so that the DTE can start sending data.

unit in the Point-to-Multipoint network, the CONNECT command must be used.
CONNECT [Unit_Numb] [/?]
Where the Unit_Numb is an assigned decimal number for the unit to be connected. To get the complete
unit list, the CONNECT command must be used with no parameter. The list of units in the Point-to-Point
link with the connection established with remote unit is shown in Figure 1:
