The ATOM one SSM500 can be controlled by a terminal connection. All commands consist
of ASCI characters.

For flexible configuration the ATOM one SSM500 provides 2 terminal interfaces:

no flow control
The ATOM one SSM500 accepts commands in text form and answers with text messages.
Every command is confirmed by "OK" or "FAIL". Errors have to be handled by the user or
host software which is used to control the device.
Depending on the
prompt
setting you get a prompt "=>" after start up. Now you can send
commands to control the device or get status information.
Check the next chapters to get detailed information about available commands and
options.
6.3 General Command Format

the

separated by a single space.
The parameters can have different formats, depending of the command. Supported
