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.
