IPI 100 and IPI 200 Series • SIS Programming and Control B-2
SIS Programming and Control
The Extron MediaLink IP Intercom 201 and 204 modules can be remotely set up
and controlled via a host computer or other device (such as a control system) by
using the Extron Simple Instruction Set (SIS ™ ) commands, accessed via RS‑232 or an
Ethernet LAN connection.
N The following SIS commands are for use with the IPI 201 and 201 models
only. Refer to the MLC 226 IP Series User’s Manual for IPI 101/104 series SIS
command and control information.
IPI RS-232 protocol:
• 38400 baud
• 8 data bits
• 1 stop bit
• no parity
• no flow control
N
The configuration port requires 38400 baud communication. This is a higher
speed than many other Extron products use. If using HyperTerminal or a
similar application, make sure the PC or control system connected to these ports
is set for 38400 baud.
LAN port defaults:
• IP address:
192.168.254.254
• gateway’s IP address: 0.0.0.0
• subnet mask: 255.255.0.0
• DHCP : off
N The IP Intercom (IPI) must be configured before use.
Host-to-IPI 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 IPI determines that
a command is valid, it executes the command and sends a response to the host
device. All responses from the IPI 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.
IPI-initiated Messages
If you are communicating with the IPI via RS‑232 or via a verbose Telnet connection
when a local event such as a front panel selection or adjustment takes place, the IPI
responds by sending a message to the host. No response is required from the host.
The IPI‑initiated messages are listed here (underlined).

Vx.xx is the firmware version number.
The IPI sends the boot and copyright messages under the following circumstances:
• If the IPI is off and an RS‑232 connection is already set up (the PC is cabled
to the IPI 204 series and a serial terminal emulation program such as
HyperTerminal is open), the connected unit sends these messages via RS‑232
when it is first powered on.
