Introduction to SIS
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. Connect the module to the host computer via RS-232 or an
Ethernet LAN connection.
NOTE:
The following SIS commands are for use with the IPI 201 and 204 models only.
Refer to the
MLC 226 IP Series Installation 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
NOTE:
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 IP address:
0.0.0.0
•
Subnet mask:
255.255.0.0
•
DHCP: off
NOTE:
The IP Intercom (IPI) must be configured before use.
