Using SIS Commands
Simple Instruction Set (SIS) commands provide an alternative way to control and configure
the WindoWall Pro processor. They are issued from a host computer or control system to
the processor by either of the communication protocols described below.
•
•
Host-to-Processor Communications
SIS commands issued from a host consist of one or more characters per command
field. They do not require any special characters to begin or end the command character
sequence. Each processor response to a command ends with a carriage return and line
feed ( ] ), which signals the end of the response character string. A string is one or more
characters.
WindoWall Pro-initiated Messages
When a local event such as an input selection or adjustment takes place, the WindoWall Pro
responds by sending a message to the host. No response is required back from the host.
Examples of processor-initiated messages are listed below (underlined).
•
Serial (RS-232 and RS-422): The WindoWall Pro can support either RS-232 or
RS-422 serial communication protocol and can operate at 9600, 19200, 38400, or
115200 baud rates.
The RS-232/422 port on the WindoWall Pro rear panel can be connected to the serial
port of a host device running the Extron DataViewer utility, to an RS-232 capable PDA,
or a control system. This connection makes software control of the processor possible.
TCP/IP (Ethernet): The rear panel Ethernet connector on the WindoWall Pro can be
connected to an Ethernet LAN or WAN. Communication between the WindoWall Pro
and the controlling device can be via Extron DataViewer or Telnet (a TCP socket using
port 23). You can change the Telnet port number, if necessary, using SIS commands (for
information on connecting via Telnet, see
To access the WindoWall Pro via the Ethernet port, obtain the IP address of the unit
(and the subnet mask and gateway address if needed) from your network administrator.
If the IP address has been changed to an address comprised of words and characters,
you can determine the actual numeric IP address using the ping (ICMP) utility (see
IP Addressing
on page 69 for more details). If the addresses have not been changed,
the factory-specified defaults are:
IP address: 192.168.254.254
•
Subnet mask: 255.255.0.0
•
Gateway address: 0.0.0.0
•
The Ethernet cable must be properly terminated for your application as either a straight-
through cable or a crossover cable (for pin assignments for these cables, see
connector
on page 7).
