RS-232/REMOTE Control
The Sentosaxi/Lanciaxi include an RS-232 communications
interface which allows it to be controlled from a Host device/
system. RS-232 connector pin assignments and protocol are
shown below.
When RS-232 data is received by the Sentosaxi/Lanciaxi, the front
panel MIN LED will blink once then the MAX LED will blink once to
indicate that RS-232 data is being received. In EXEC mode the
MIN and MAX LEDs are solid ON (see Page 2-5), they don't blink.
A contact closure device may also be used on the RS-232
connector, See "Remote Contact Closure Operation" – Page 3-5.
Host/Sentosaxi xi xi xi xi/Lanciaxi xi xi xi xi Communications
The Sentosaxi/Lanciaxi treats any character that it receives on the
RS-232 port as a possible command but accepts only a limited
number as legal commands. There are no codes required to say
that a command is coming, or that a command has ended. A
simple command may be a single character typed on a keyboard
and does not require any special characters before or after. (i.e. It
is not necessary to press "enter" from the keyboard.) Simple
commands could be from a terminal, or any other Host device.
When the Sentosaxi/Lanciaxi receives a command and determines
that it is valid, it will execute the command and send a response
back to the controlling (Host) device. If the Sentosaxi/Lanciaxi
determines that the command is invalid, an error response will be
returned to the Host. All responses from the Sentosaxi/Lanciaxi to
the Host end with a carriage return and a line feed (CR/LF)
signaling the end of the Response character string (string = one or
more characters).
Using the Command/Response Table
The table on the following page lists those commands which the
Sentosaxi/Lanciaxi recognizes as valid and the responses that will
be returned to the Host. The Description column defines the
Command, the results of executing the Command, or a definition
of the response. An example of each command is shown to the
right of the Command Description column. The error response
format is shown at the bottom of the table. Possible error types
and causes are shown on page 3-3 followed by Sentosaxi/Lanciaxi
initiated messages.
A dot (·) when used in the table represents a space. It is not
displayed.
