WindoWall Pro Series • Remote Configuration and Control 30

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.

• 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 Connecting as a Telnet Client on page 72).

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

LAN

connector on page 7).

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).

• The WindoWall Pro sends the copyright message when it is first powered on. Vn.n is

the firmware version number, and 60-nnnn-nn is the part number of the processor.

The current date and time are displayed following the copyright message at power up if

the connection is via the Internet. (Www are the first three letters of the day of the week,

for example, Mon or Fri.)
