xi • RS-232/Remote Control
RS-232/Remote Control, cont’d
The Lanciaxi line doubler’s rear panel RS-232/Remote connector
(figure 6) can be connected to the serial port output of a host
device, such as a computer or control system, or to a remote
contact closure device. Remote communications with the
Lanciaxi are via Extron’s Simple Instruction Set, Extron’s
Windows-based control program, or pin-programmed in the
case of a contact closure device.

Figure 6 — RS-232/Remote connector pinout
The RS-232 protocol of the rear panel RS-232/Remote connector
is 9600 baud, 1 stop bit, no parity, and no flow control. When
the Lanciaxi receives an RS-232 communication, the front panel
Min LED blinks once, then the Max LED blinks. (In Executive
mode, the LEDs are on and do not blink.) The connector has the
following pin assignments:

Host-to-interface communications
SIS commands consist of one or more characters per field. No
special characters are required to begin or end a command
character sequence. When a command is valid, the Lanciaxi
executes the command and sends a response to the host device.
All responses from the Lanciaxi to the host end with a carriage
return and a line feed (CR/LF = ), which signals the end of
the response character string. A string is one or more characters.
