IPI 201/204 SIS™ Programming and Control
The Extron MediaLink IP Intercom modules can be remotely set up and controlled via a host computer or other device (such as a control system) attached to the LAN port, or the front panel Config port.
NRefer to the MLC 226 IP Series User’s Manual for IPI 101/104 series SIS command and control information.
The IPI can be set up and controlled by using Extron’s Simple Instruction Set (SIS) commands, accessed via
IPI RS-232 protocol:
•38400 baud
•8 data bits
•1 stop bit
•no parity
•no flow control
NThe 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
NThe 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.
