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:
