Extron electronic Ultra Series, MAV Plus Series Default IP addresses, Establishing a connection

Default IP addresses

To access the CrossPoint or MAV Plus switcher via the LAN port, you need the Extron IP address, and may need the subnet mask and the gateway address. If the IP address has been changed to an address comprised of words and characters, you can determine the actual numeric IP address using the ping (ICMP) utility (see appendix A, “Ethernet Connection”, for more details). If the addresses have not been changed, the factory-specified defaults are:

•	IP address	192.168.254.254
• Gateway address		0.0.0.0
•	Subnet mask	255.255.0.0

Establishing a connection

Establish a network connection to a CrossPoint or MAV Plus switcher as follows: 1. Open a TCP socket to port 23 using the switcher’s IP address.

NIf the local system administrators have not changed the value, the factory- specified default, 192.168.254.254, is the correct value for this field.

The switcher responds with a copyright message including the date, the name of the product, firmware version, part number, and the current date/time.

NIf the switcher is not password-protected, the device is ready to accept SIS commands immediately after it sends the copyright message.

NIf the switcher is password-protected, a password prompt appears below the copyright message.

2. If the switcher is password protected, enter the appropriate administrator or user password.

If the password is accepted, the switcher responds with Login User or Login Administrator.

If the password is not accepted, the Password prompt reappears.

Connection Timeouts

The Ethernet link times out after a designated period of time of no communications. By default, this timeout value is set to 5 minutes but the value can be changed. See the Configure port timeout commands on page 4-25.

NExtron recommends leaving the default timeout at 5 minutes and periodically issuing the Query (Q) command to keep the connection active. If there are long idle periods, Extron recommends disconnecting the socket and reopening the connection when another command must be sent.

Number of connections

A CrossPoint or MAV Plus switcher can have up to 200 simultaneous TCP connections, including all http sockets and Telnet connections. When the connection limit is reached, the switcher accepts no new connections until some have been closed. No error message or indication is given that the connection limit has been reached. To maximize performance of an IP Link device, the number of connections should stay low and unnecessary open sockets should be closed.
