SIS™ Programming and Control

The IPL 250 can be remotely controlled via a host computer, touchpanel, or other

device (such as a control system) attached to a shared network.

The IPL must be conﬁgured before use. As shipped the controller/processor

cannot control any other devices or interact with a touchpanel before being

conﬁgured. Set up the IPL or control it by using Extron Simple Instruction Set

(SIS™) commands or Extron Global Conﬁgurator software (version 3.0 or higher),

via Ethernet LAN connection. See chapter 2 for pin assignments and protocol. For

information on the software and the embedded Web pages, see chapter 3 and refer

to the software’s help ﬁles.

IPL 250 LAN port defaults:

• IPL’s IP address: 192.168.254.254

•gateway’s IP address: 0.0.0.0

•subnet mask: 255.255.0.0

•DHCP: off

Host-to-IPL Communications

SIS commands consist of one or more characters per ﬁeld. No special characters

are required to begin or end a command sequence. When the IPL determines that

a command is valid, it executes the command and sends a response to the host

device. All responses from the IPL 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.

IPL 250-initiated messages

If you are communicating with the IPL via a verbose Telnet connection, when a

local event such as a selection via a touchpanel takes place, the IPL responds by

sending a message to the host. No response is required from the host. The IPL-

initiated messages are listed here).

Vx.xx is the ﬁrmware version number.

Example:

Wed, 29 Jul 2009 14:53:34

The IPL 250 sends the boot and copyright messages when you ﬁrst open a Telnet

connection to the IPL. You can see the day of the week, date, and time if the unit is

connected via Telnet. If you use a Telnet connection, the copyright message, date,

and time may be followed by a password prompt.

Additional messages may be sent by the IPL in response to changes made through

the touchpanel and when scripts are executed during scheduled events.

Password information

The “]Password:” prompt requires a password (administrator level or user level)

followed by a carriage return. The prompt is repeated if the correct password is not

entered.

If the correct password is entered, the unit responds with

“]Login Administrator ]”, “******]Login Administrator]”, or

“]Login User]”, depending on the password entered. If passwords are the same

for both administrator and user, the unit defaults to administrator privileges.
