Control Via ET Commands
As default the ETM9900(J) is set to ET Command Mode, ET Commands are specific to ETM
terminals and allow for control, configuration and information requests to be sent to and from the
terminal. In ETM command mode AT commands cannot be sent to the unit.
ET commands can be sent via SMS or from configuration tool when directly connected or via an IP
or CSD connection. It is recommended that more complex settings such as changing messages or
phone numbers are made using the configuration tool.
Common ET commands are shown below, for a full ET command list download the relevant
documents from Docbanq (see page 3).
