Operation
Command Formats
The GPI-16 Plus/RJ may be configured to use either the PIP or AT1616 (input only)
serial format. The PIP serial format (default) is listed below and requires the use of
the unit ID to request input status (polling) or with a unit ID of zero (non-polling)
the GPI-16 Plus/RJ will send a serial status string each time an input changes state.
When the unit is restarted (power-up), unit information is issued in either mode.
