3.2. Command Mode 
When iWEM-1000 is powered up, the default operation mode is data mode. To enter command mode, send 
escape characters “+++” to iWEM-1000 through the UART port. iWEM-1000 will respond with the 
command prompt characters “>”. The user sets and checks the configuration of iWEM-1000 in command 
mode. The user can use a host controller or a terminal emulator to send ascii commands to iWEM-1000 
UART port to set communication parameters or view them. The response is also in readable ascii format. 
 
When iWEM-1000 in command mode, iWEM-1000 takes defined ascii command sets. To exit command 
mode, send “exit<cr>” to the UART port. iWEM-1000 will respond with “DATA<cr>” and “>” to the 
terminal and switch to data mode. 
 
The UART setting of the host controller or data terminal must match the iWEM-1000 UART setting in 
order to communicate. iWEM-1000 default UART setting is 9600bps, 8 data bits, 1 start/stop bit, and no 
flow control.   
 
The user can use any preferred terminal program like Teraterm, or Hyperterm to connect to the iWEM-1000 
through COM port. Teraterm is recommended because of its popularity and user friendliness. You can go to 
the official Teraterm site to download the latest Teraterm application: 
 
3.3.  Save Updated Configuration 
After the user updates the configuration in command mode, the user must save the new configuration into 
the flash memory. Send “save” command to iWEM-1000 after the new configuration is set. The new 
configuration will be saved into the flash memory. The new setting will take effect after the user reboots 
iWEM-1000. 
 
4. Command 
Interface 
This section describes syntax and commands used in command interface for the user to set and check the 
iWEM-1000 configuration. 
 
4.1. Escape Characters to Enter Command Mode 
In order to get into command from default data mode, the user must send time-guarded escape characters to 
the UART port. The format is: <500ms guard time>+++<500ms guard time>. If the guard time is less 
than 500ms, the escape characters will be discarded and iWEM-1000 will not get into command mode. 
 
4.2. Command Type 
There are three types of commands:
