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ow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.

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.
