Hardware Switching to Command Mode

3.1.2. Hardware Switching to Command Mode
As alternative to Software Switching, the switching through the MP/DP (Data Terminal Ready,
DTR) control line can be used. To set Command Mode, the DTE must assert DTR signal active
and then passive. By falling edge of DTR signal the unit goes to command mode and then sends
Escape-Acknowledge to DTE ("@00<CR><LF>").
20 ms toggling on CTS control line needed to acknowledge switching from Data to Command
mode and vice versa.
Note:
The powered up radio modem by default goes to Data Mode regardless of DTR control line
polarity.

3.1.3. Switching to Data Mode

• DTE sends the CLI command "DATAMODE<CR><LF>" to the unit.
• Unit answers with Escape-Acknowledge („@00<CR><LF>") and immediately goes to
datamode, so that the DTE can start sending data as soon as the Escape-Acknowledge has
been received.
• 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 longer then 15 second.
