Switching to Data Mode
24 www.javad.com
DTE must assert DTR signal active (0v level). By falling edge of DTR signal the unit goes to
Maintenance mode and then sends Escape-Acknowledge to DTE („@00<CR><LF>“).
20 ms toggling on CTS control line followed by Escape-Acknowledge response is needed to
acknowledge switching from Data to Maintenance mode and vice versa. In Maintenance Mode,
the unit’s serial port must keep Clear to Send (CTS) line always active (see also “MPORT” on
page 27).
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.

3.2.1. CONNECT
To connect the radio unit through the local maintenance serial port or to establish the link with the
remote 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 3-1:
